What Is L⋆?: Anatomy of the Galaxy Luminosity Function
Using the empirical relations between the central galaxy luminosity and the halo mass, and between the total luminosity of galaxies in a halo and the halo mass, we construct the galaxy luminosity function (LF). To the luminosity of the central galaxy in a halo of a given mass we assign log-normal scatter with the mean and the dispersion of the luminosity directly calibrated against the observat...
متن کاملWhat Is the Cosmic-ray Luminosity of Our Galaxy?
The total cosmic-ray luminosity of the Galaxy is an important constraint on models of cosmic-ray generation. The diffuse high energy γ-ray and radio-synchrotron emissions of the Milky Way are used to derive this luminosity. The result is almost two orders of magnitude larger than the standard estimate, based on the observed isotopic abundances of cosmic ray nuclides. We discuss the plausible in...
متن کاملBeyond 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...
