The Fornax cluster provides an unparalleled opportunity to investigate in detail the formation and evolution of early-type galaxies in a dense environment. We aim at kinematically characterizing photometrically detected globular cluster (GC) candidates in the core of the cluster. We used the VLT/VIMOS spectroscopic data from the FVSS survey in the Fornax cluster, covering one square degree around the central massive galaxy NGC 1399. We confirmed a total of 777 GCs, almost doubling the previously detected GCs, using the same dataset by Pota et al. (2018). Combined with previous literature radial velocity measurements of GCs in Fornax, we compiled the most extensive spectroscopic GC sample of 2341 objects in this environment. We found that red GCs are mostly concentrated around major galaxies, while blue GCs are kinematically irregular and are widely spread throughout the core region of the cluster. The velocity dispersion profiles of blue and red GCs show a quite distinct behaviour. Blue GCs exhibit a sharp increase in the velocity dispersion profile from 250 to 400km/s within 5 arcminutes (29 kpc/1 reff of NGC 1399) from the central galaxy. The velocity dispersion profile of red GCs follows a constant value in between 200-300km/s until 8 arcminutes (46 kpc/1.6reff), and then rises to 350km/s at 10 arcminutes (58 kpc/2 reff). Beyond 10 arcminutes and out to 40 arcminutes (230 kpc/8 reff), blue and red GCs show a constant velocity dispersion of 300+/-50km/s, indicating that both GC populations are tracing the cluster potential. We have kinematically confirmed and characterized the previously photometrically discovered overdensities of intra-cluster GCs. We found that those substructured intra-cluster regions in Fornax are dominated mostly by blue GCs., 22 Pages, 22 Figures. Accepted for publication in Astronomy and Astrophysics

Background: HIV is an important risk factor for the development of tuberculosis. People living with HIV are 21-34 times more likely to develop TB than their uninfected counterparts. Efficient approach for detecting more cases along with shortened duration of infectivity involves a systematic screening of pulmonary TB in settings where high risk groups are concentrated even before the diagnosis HIV infection. Lack of proper screening strategy for HRGs might result in their exclusion from timely intervention which may prove lethal without treatment.Methods: A cross sectional study was carried out in two districts of Chhattisgarh during September-December 2019.Training cum sensitization sessions were conducted for peer educators, outreach workers, counselors and project managers prior to the survey and were trained for systematic screening of pulmonary TB, sputum collection and transportation to GeneXpert®MTB/RIF lab and other relevant data collection for pulmonary TB diagnosis.Results: A total of 3963 HRGs were intended to be included in the study, 3418 were screened with 86.2% compliance rate. Out of all HRGs screened (3418), 81 (2.4%) were found presumptive pulmonary TB, of them 2 (0.05%) were microbiologically confirmed, 5 cases were found with incomplete treatment (all were IDUs). Prevalence of tobacco use, alcohol use, diabetes and hypertension were observed in 5.3% and 7.2%, 1.2% and 1.1 respectively.Conclusions: Although yield for pulmonary TB in this study was not much, the study has demonstrated that active case finding for accessing such a hidden population through existing manpower can assure better acceptability and feasibility in resource poor settings.
