Beyond the galaxy luminosity function
With the advent of large scale surveys (i.e., Legacy Surveys) it is now possible to start looking beyond the galaxy luminosity function (LF) to more detailed statistical representations of the galaxy population, i.e., multivariate distributions. In this review I first summarise the current state-of-play of the B-band global and cluster LFs and then briefly present two promising bivariate distri...
متن کاملEvolution of Galaxy Luminosity Function and Luminosity Function by Density
Using galaxy sample observed by the BATC large-field multi-color sky survey and galaxy data of SDSS in the overlapped fields, we study the dependence of the restframe r-band galaxy luminosity function on redshift and on large-scale environment. The large-scale environment is defined by isodensity contour with density contrast δρ/ρ. The data set is a composite sample of 69,671 galaxies with reds...
متن کاملThe Nearby Optical Galaxy Sample: the Local Galaxy Luminosity Function
In this paper we derive the galaxy luminosity function from the Nearby Optical Galaxy (NOG) sample, which is a nearly complete, magnitude–limited (B ≤14 mag), all–sky sample of nearby optical galaxies (∼6400 galaxies with cz < 5500 km s−1 ). For this local sample, we use galaxy distance estimates based on different peculiar velocity models. Therefore, the derivation of the luminosity function i...
متن کاملThe K - Band Galaxy Luminosity Function 12
We measured the K-band luminosity function using a complete sample of 4192 morphologically-typed 2MASS galaxies with Ks = 20 mag/arcsec 2 isophotal magnitudes 7 < K 20 < 11:25 mag spread over 2:12 str. Early-type (T ?0:5) and late-type (T > ?0:5) galaxies have similarly shaped luminosity functions, for H 0 = 100h km s ?1 Mpc ?1 , such that the late-type galaxies slightly dominate the K-band lum...
