Author

Abstract

In this paper, we present a set of photometric observations in 15 colors of stars in the Landolt SA95 field with the BATC system. The wavelengths covered by the system range from 300 nm to 1000 nm. Visual magnitudes of the stars studied in the field are from the 10th to 20th mag. The observational methodology and the data reduction procedures are described. The relationships between the BATC intermediate-band system and the Landolt UBVRIbroad band system are obtained. A catalogue of the photometry has been produced which contains the SEDs of 3613 stars.

117. Evolution of the Galaxy Luminosity Function for Redshift and Density Environment at 0.03 < z < 0.5

Author

Abstract

Using the galaxy sample observed by the Beijing-Arizona-Taiwan-Connecticut (BATC) large-field multicolor sky survey and the galaxy data of the Sloan Digital Sky Survey (SDSS) in overlapping fields, we study the dependence of the rest-frame r-band galaxy luminosity function on redshift and on the large-scale environment. The large-scale environment is defined by isodensity contours with density contrast dr/r. The data set is a composite sample of 69,671 galaxies with redshifts 0.03 < z < 0.5 and r < 21.5 mag. The redshift data are composed of three parts: (1) spectroscopic redshifts in SDSS for local and the most luminous galaxies, (2) 20-color photometric redshifts derived from BATC and SDSS, and (3) five-color photometric redshifts in SDSS. We find that the faint-end slope a steepens slightly from -1.21 at z ~ 0.06 to -1.35 at z ~ 0.4, which is the natural consequence of the hierarchical formation of galaxies. The luminosity function also differs with different environments. The value of a changes from -1.21 in underdense regions to -1.37 in overdense regions, and the corresponding M* brightens from -22.26 to -22.64. This suggests that the fraction of faint galaxies is larger in high-density regions than in low-density regions.

Abstract

We present the [O II] (lambda lambda 3729; 3726) luminosity function measured in the redshift range 0.1 < z < 1.65 with unprecedented depth and accuracy. Our measurements are based on medium resolution flux-calibrated spectra of emission line galaxies with the visual and near UV FOcal Reducer and low dispersion Spectrograph (FORS2) for the Very Large Telescope (VLT) of the European Southern Observatory (ESO) and with the SDSS-III/BOSS spectrograph. The FORS2 spectra and the corresponding catalog containing redshifts and line fluxes are released along with this paper. In this work we use a novel method to combine these surveys with GAMA, zCOSMOS, and VVDS, which have di ff erent target selection, producing a consistent weighting scheme to derive the [O II] luminosity function. The [O II] luminosity function is in good agreement with previous independent estimates. The comparison with two stateof- the-art semi-analytical models is good, which is encouraging for the production of mock catalogs of [O II] flux limited surveys. We observe the bright end evolution over 8.5 Gyr: we measure the decrease of log L-* from 42.4 erg/s at redshift 1.44 to 41.2 at redshift 0.165 and we find that the faint end slope flattens when redshift decreases. This measurement confirms the feasibility of the target selection of future baryonic acoustic oscillation surveys aiming at observing [OII] flux limited samples.
