MAGNITUDE GAP STATISTICS AND THE CONDITIONAL LUMINOSITY FUNCTION

The Luminosity Function of Magnitude and Proper - Motion Selected Samples

The luminosity function of white dwarfs is a powerful tool for studies of the evolution and formation of the Milky Way. The (theoretical) white dwarf cooling sequence provides a useful indicator of the evolutionary time scales involved in the chronometry and star formation history of the galactic disk, therefore, intrinsically faint (& old) white dwarfs in the immediate solar neighborhood can b...

Conditional Luminosity Function Models of Luminosity-dependent Correlation Functions⋆

Using the conditional luminosity function (CLF) — the luminosity distribution of galaxies in a dark matter halo — as a way to model galaxy statistics, we study how z = 4 Lyman Break Galaxies (LBGs) are distributed in dark matter halos. For this purpose, we measure luminosity-dependent clustering of LBGs in the Subaru/XMMNewton Deep Field by separating a sample of 16,920 galaxies to three magnit...

Differential Density Statistics of Galaxy Distribution and the Luminosity Function

This paper uses data obtained from the galaxy luminosity function (LF) to calculate two types of radial number densities statistics of the galaxy distribution as discussed in Ribeiro (2005), namely the differential density γ and the integral differential density γ. By applying the theory advanced by Ribeiro and Stoeger (2003), which connects the relativistic cosmology number counts with the ast...

The Luminosity Function of Magnitude and Proper-Motion Selected Samples. The case of White-Dwarfs

The luminosity function of white dwarfs is a powerful tool for studies of the evolution and formation of the Milky Way. The (theoretical) white dwarf cooling sequence provides a useful indicator of the evolutionary time scales involved in the chronometry and star formation history of the galactic disk, therefore, intrinsically faint (& old) white dwarfs in the immediate solar neighborhood can b...
