GALACTIC redshift ,GALAXY spectra ,STAR formation ,HIGH resolution imaging ,STELLAR structure - Abstract
Exploiting the deep high-resolution imaging of all five CANDELS fields, and accurate redshift information provided by 3D-HST, we investigate the relation between structure and stellar populations for a mass-selected sample of 6764 galaxies above 10
10 M☼ , spanning the redshift range 0.5 < z < 2.5. For the first time, we fit two-dimensional models comprising a single Sérsic fit and two-component (i.e., bulge + disk) decompositions not only to the H-band light distributions, but also to the stellar mass maps reconstructed from resolved stellar population modeling. We confirm that the increased bulge prominence among quiescent galaxies, as reported previously based on rest-optical observations, remains in place when considering the distributions of stellar mass. Moreover, we observe an increase of the typical Sérsic index and bulge-to-total ratio (with median B/T reaching 40%-50%) among star-forming galaxies above 1011 M☼ . Given that quenching for these most massive systems is likely to be imminent, our findings suggest that significant bulge growth precedes a departure from the star-forming main sequence. We demonstrate that the bulge mass (and ideally knowledge of the bulge and total mass) is a more reliable predictor of the star-forming versus quiescent state of a galaxy than the total stellar mass. The same trends are predicted by the state-of-the-art, semi-analytic model by Somerville et al. In this model, bulges and black holes grow hand in hand through merging and/or disk instabilities, and feedback from active galactic nuclei shuts off star formation. Further observations will be required to pin down star formation quenching mechanisms, but our results imply that they must be internal to the galaxies and closely associated with bulge growth.

STAR formation ,ACTIVE galactic nuclei ,SHOCK heating ,DARK matter ,STELLAR mass ,GALACTIC bulges - Abstract
The shutdown of star formation in galaxies is generally termed “quenching.” Quenching may occur through a variety of processes, e.g., active galactic nucleus (AGN) feedback, stellar feedback, or the shock heating of gas in the dark matter halo. However, which mechanism(s) is, in fact, responsible for quenching is still in question. This paper addresses quenching by searching for traces of possible quenching processes through their effects on galaxy structural parameters such as stellar mass (M
* ), M* /re , surface stellar mass density (∼M* /r2 e ), and Sérsic index (n). We analyze the rest-frame U – B color correlations versus these structural parameters using a sample of galaxies in the redshift range 0.5 ⩽ z < 0.8 from the DEEP2/AEGIS survey. In addition to global radii, stellar masses, and Sérsic parameters, we also use “bulge” and “disk” photometric measurements from GIM2D fits to HST/ACS V and I images. We assess the tightness of the color relationships by measuring their “overlap regions,” defined as the area in color-parameter space in which red and blue galaxies overlap; the parameter that minimizes these overlap regions is considered to be the most effective color discriminator. We find that Sérsic index (n) has the smallest overlap region among all tested parameters and resembles a step function with a threshold value of n = 2.3. There exists, however, a significant population of outliers with blue colors yet high n values that seem to contradict this behavior; they make up ≈40% of n > 2.3 galaxies. We hypothesize that their Sérsic values may be distorted by bursts of star formation, AGNs, and/or poor fits, leading us to consider central surface stellar mass density, Σ*1 kpc , as an alternative to Sérsic index. Not only does Σ*1 kpc correct the outliers, but it also forms a tight relationship with color, suggesting that the innermost structure of galaxies is most physically linked with quenching. Furthermore, at z ∼ 0.65, the majority of the blue cloud galaxies cannot simply fade onto the red sequence since their GIM2D bulge masses are only half as large on average as the bulge masses of similar red sequence galaxies, thus demonstrating that stellar mass must absolutely increase at the centers of galaxies as they quench. We discuss a two-stage model for quenching in which galaxy star formation rates are controlled by their dark halos while they are still in the blue cloud and a second quenching process sets in later, associated with the central stellar mass buildup. The mass buildup is naturally explained by any non-axisymmetric features in the potential, such as those induced by mergers and/or disk instabilities. However, the identity of the second quenching agent is still unknown. We have placed our data catalog online. [ABSTRACT FROM AUTHOR]- Published

GALACTIC evolution ,GALAXY formation ,STELLAR mass ,GALACTIC dynamics - Abstract
We use HST/WFC3 imaging from the CANDELS Multi-Cycle Treasury Survey, in conjunction with the Sloan Digital Sky Survey, to explore the evolution of galactic structure for galaxies with stellar masses >3 × 10
10 M☼ from z = 2.2 to the present epoch, a time span of 10 Gyr. We explore the relationship between rest-frame optical color, stellar mass, star formation activity, and galaxy structure. We confirm the dramatic increase from z = 2.2 to the present day in the number density of non-star-forming galaxies above 3 × 1010 M☼ reported by others. We further find that the vast majority of these quiescent systems have concentrated light profiles, as parameterized by the Sérsic index, and the population of concentrated galaxies grows similarly rapidly. We examine the joint distribution of star formation activity, Sérsic index, stellar mass, inferred velocity dispersion, and stellar surface density. Quiescence correlates poorly with stellar mass at all z < 2.2. Quiescence correlates well with Sérsic index at all redshifts. Quiescence correlates well with “velocity dispersion” and stellar surface density at z > 1.3, and somewhat less well at lower redshifts. Yet, there is significant scatter between quiescence and galaxy structure: while the vast majority of quiescent galaxies have prominent bulges, many of them have significant disks, and a number of bulge-dominated galaxies have significant star formation. Noting the rarity of quiescent galaxies without prominent bulges, we argue that a prominent bulge (and perhaps, by association, a supermassive black hole) is an important condition for quenching star formation on galactic scales over the last 10 Gyr, in qualitative agreement with the active galactic nucleus feedback paradigm.

We present a study on spectral energy distributions, morphologies, and star formation for an IRAC-selected extremely red object sample in the GOODS Chandra Deep Field-South. This work was enabled by new HST/WFC3 near-IR imaging from the CANDELS survey as well as the deepest available X-ray data from Chandra 4 Ms observations. This sample consists of 133 objects with the 3.6 μm limiting magnitude of [3.6] = 21.5 and is approximately complete for galaxies with M
* > 1011 M☼ at 1.5 ⩽ z ⩽ 2.5. We classify this sample into two types, quiescent and star-forming galaxies (SFGs), in the observed infrared color-color ([3.6]–[24] versus K – [3.6]) diagram. The further morphological study of this sample shows a consistent result with the observed color classification. The classified quiescent galaxies are bulge dominated and SFGs in the sample have disk or irregular morphologies. Our observed infrared color classification is also consistent with the rest-frame color (U – V versus V – J) classification. We also found that quiescent and SFGs are well separated in the nonparametric morphology parameter (Gini versus M20 ) diagram measuring their concentration and clumpiness: quiescent galaxies have a Gini coefficient higher than 0.58 and SFGs have a Gini coefficient lower than 0.58. We argue that the star formation quenching process must lead to or be accompanied by the increasing galaxy concentration. One prominent morphological feature of this sample is that disks are commonly seen in this massive galaxy sample at 1.5 ⩽ z ⩽ 2.5: 30% of quiescent galaxies and 70% of SFGs with M* > 1011 M☼ have disks in their rest-frame optical morphologies. The prevalence of these extended, relatively undisturbed disks challenges the merging scenario as the main mode of massive galaxy formation. [ABSTRACT FROM AUTHOR]- Published

- Abstract
We investigate the stellar structure of massive, quiescent galaxies at z [?] 2, based on Hubble Space Telescope/WFC3 imaging from the Early Release Science program. Our sample of 14 galaxies has stellar masses of M * > 1010.8 M and photometric redshifts of 1.5 < z < 2.5. In agreement with previous work, their half-light radii are <2 kpc, much smaller than equally massive galaxies in the present-day universe. A significant subset of the sample appears highly flattened in projection, which implies, considering viewing angle statistics, that a significant fraction of the galaxies in our sample have pronounced disks. This is corroborated by two-dimensional surface brightness profile fits. We estimate that 65% +- 15% of the population of massive, quiescent z [?] 2 galaxies are disk dominated. The median disk scale length is 1.5 kpc, substantially smaller than the disks of equally massive galaxies in the present-day universe. Our results provide strong observational evidence that the much-discussed ultra-dense high-redshift galaxies should generally be thought of as disk-like stellar systems with the majority of stars formed from gas that had time to settle into a disk.

We report on the host properties of five X-ray-luminous active galactic nuclei (AGN) identified at 3 < z < 5 in the first epoch of imaging from the Cosmic Evolution Early Release Science Survey. Each galaxy has been imaged with the JWST Near-Infrared Camera, which provides rest-frame optical morphologies at these redshifts. We also derive stellar masses and star formation rates for each host by fitting its spectral energy distribution using a combination of galaxy and AGN templates. We find that three of the AGN hosts have spheroidal morphologies, one is a bulge-dominated disk, and one is dominated by pointlike emission. None are found to show strong morphological disturbances that might indicate a recent interaction or merger event. When compared to a sample of mass-matched inactive galaxies, we find that the AGN hosts have morphologies that are less disturbed and more bulge-dominated. Notably, all four of the resolved hosts have rest-frame optical colors consistent with a quenched or poststarburst stellar population. The presence of AGN in passively evolving galaxies at z > 3 is significant because a rapid feedback mechanism is required in most semianalytic models and cosmological simulations to explain the growing population of massive quiescent galaxies observed at these redshifts. Our findings show that AGN can continue to inject energy into these systems after their star formation is curtailed, potentially heating their halos and preventing renewed star formation. Additional observations will be needed to determine what role this feedback may play in helping to quench these systems and/or maintain their quiescent state.

- Abstract
Objectives: Most patients receiving curative-intent surgery for pancreatic cancer will experience cancer recurrence. However, evidence that postoperative surveillance testing improves survival or quality of life is lacking. We evaluated the use and characteristics of surveillance with serial imaging and CA 19-9 tumor marker testing at an NCI-designated comprehensive cancer center., Methods: We conducted a retrospective cohort study of patients who entered surveillance after curative-intent resection of pancreatic adenocarcinoma. We abstracted information from the electronic medical record about oncology office visits, surveillance testing (cross-sectional imaging and CA 19-9 tumor marker testing), and pancreatic cancer recurrence, with follow-up through 2 years after pancreatectomy. We conducted analyses to describe the use of surveillance testing and to characterize the sensitivity and specificity of CA 19-9 tumor marker testing for the identification of cancer recurrence., Results: We identified 90 patients entering surveillance after pancreatectomy. CA 19-9 was the most frequently used surveillance test, followed by CT imaging. Forty-seven patients (52.2%) experienced recurrence within two years of pancreatectomy. Recurrence risk was 58.8% versus 31.8% in patients with elevated versus normal CA 19-9 at diagnosis ( P =0.03). Elevated CA 19-9 at any point during surveillance was significantly associated with 2-year recurrence risk ( P <0.001). Elevated CA 19-9 had a sensitivity of 83% (95% CI 0.72-0.95) and specificity of 87% (0.76-0.98) for identification of recurrence within 2 years of pancreatectomy., Conclusions: CA 19-9 demonstrates clinical validity for identifying recurrence of pancreatic cancer during surveillance. Surveillance approaches with reduced reliance on imaging should be prospectively evaluated., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

- Abstract
Purpose: Cancer survivorship care planning is a recognized yet underutilized aspect of care delivery, and the opportunity for telehealth in cancer survivorship is examined., Methods: We conducted a mixed-methods study in Vermont and New Hampshire to characterize perceptions of rural cancer providers and survivors regarding survivorship transitions in care, consisting of (a) key informant interviews with primary care and oncology clinicians, (b) a broader survey of clinicians, and (c) surveys and focus group discussions with cancer survivors. In these interactions, we also explored the use of a shared telehealth survivorship care planning appointment between oncology clinicians, primary care clinicians, and survivors., Results: Results from surveys and interviews clustered around several themes, namely (1) infrequent care transitioning back to primary care, (2) lack of mental health services, (3) lack of side effect education, (4) low perceived utility of survivorship care plans, (5) clinicians exclusively communicate using the EMR and finding it imperfect, and (6) clinicians and survivors reported conflicting perceptions regarding survivors' access to telehealth options., Conclusions: Our results suggest that telehealth has the potential to augment the delivery of survivorship care planning; however, key technical and logistical concerns need to be addressed, particularly enhanced coordination across clinician scheduling and ensuring payment parity for various telehealth implementation strategies., Implications for Cancer Survivors: Cancer survivorship care planning is a recognized yet underutilized aspect of care delivery. There is an opportunity for the application of telehealth for supportive care in survivorship care planning, which should be a focus of further research., (© 2023.

- Abstract
The provision of spiritual care is referred to in professional practice guidelines and mandated in nurses' ethical codes. Still, a gap exists regarding essential training in spiritual conversation and assessment, leaving some health care providers feeling uncomfortable when assessing spiritual support needs. The purpose of this study was to assess hospice and palliative nurses' and holistic nurses' perceptions of spirituality and spiritual care. It was assumed that the standards of care for hospice and palliative nurses and holistic nurses stipulate that spiritualty is addressed within the framework of their specialties and provide education for spiritual care, thus making these nurses proficient in providing spiritual care. This exploratory, descriptive study utilized a web-based survey to measure perception of spirituality and spiritual care giving using a modified Spirituality and Spiritual Care Rating Scale. A convenience sample was recruited from members of the Hospice and Palliative Nurses Association and the American Holistic Nurses Association (n = 250). Descriptive statistics summarized data as well as qualitative analysis of written narratives. Content analysis of open-ended survey questions was used to identify themes until saturation. This study found that given adequate resources and education, nurses can be positioned to address the spiritual needs of patients and provide appropriate care. This study adds to an emerging body of evidence suggesting that training in spiritual care should be an important component of the foundational nursing curriculum., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2020 by The Hospice and Palliative Nurses Association.

- Abstract
Research has demonstrated that cancer survivors who receive a survivorship care plan (SCP) have better coordinated follow-up care, higher overall satisfaction, and report significantly fewer posttreatment emotional concerns. The Commission on Cancer, a program of the American College of Surgeons, has developed a standard of care in which 100% of eligible patients are to receive an SCP by the end of 2019. Nurse practitioners at a National Cancer Institute (NCI)-designated academic medical center worked to develop a standardized process to deliver SCPs to all eligible patients. The primary objective of the project was to standardize how SCPs were completed and embed them into the electronic medical record (EMR) using a templated note created for the EMR. Through an interdisciplinary steering committee, survivorship priorities were established and aligned with LIVE STRONG and American Society of Clinical Oncology guidelines. In addition, survivorship care planning was identified as an essential service to be provided by all cancer disease management groups (DMG) at the cancer center. A cancer SCP subcommittee was formed to explore methods to expand the delivery of SCPs and standardize the SCP process. Prior to this project, SCPs were being done by less than 10% of the providers and only for a few diagnoses, and no standardized method of documentation existed prior to this quality improvement initiative. The standardization of the SCP has increased both participation of other DMGs as well as increased the rate of completion to 34%. We believe that continuous reassessment and process improvement will help us reach the Commission on Cancer goal of providing SCPs to all eligible patients., Competing Interests: The authors have no conflicts of interest to disclose., (© 2019 Harborside™.)
