SPIDER - V. Measuring Systematic Effects in Early-Type Galaxy Stellar Masses from Photometric SED Fitting
Measuring Systematic Effects Early-Type Galaxy Stellar Masses Photometric
2011/10/17
We present robust statistical estimates of the accuracy of early-type galaxy stellar masses derived from spectral energy distribution (SED) fitting as functions of various empirical and theoretical as...
Star Formation Rates and Stellar Masses of H-alpha Selected Star-Forming Galaxies at z=0.84: A Quantification of the Downsizing
Star Formation Rates Stellar Masses H-alpha Selected Star-Forming Galaxies Quantification Downsizing
2011/10/13
In this work we analyze the physical properties of a sample of 153 star forming galaxies at z~0.84, selected by their H-alpha flux with a NB filter. B-band luminosities of the objects are higher than ...
Dynamical versus Stellar Masses of Ultracompact Dwarf Galaxies in the Fornax Cluster
galaxies dwarf – galaxies elliptical and lenticular cD – galaxies evo-lution – galaxies stellar content – galaxies kinematics and dynamics
2010/11/12
The origin of ultracompact dwarf (UCD) galaxies, compact extragalactic stellar sys-tems, is still a puzzle for present galaxy formation models. We present the compre-hensive analysis of high resolutio...
WINGS-SPE II: A catalog of stellar ages and star formation histories, stellar masses and dust extinction values for local clusters galaxies
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
The WIde-field Nearby Galaxy clusters Survey (WINGS) is a project whose primary goal is to study the galaxy populations in clusters in the local universe (z<0.07) and of the influence of environment o...
Entropy Maximization, Cutoff Distribution, and Finite Stellar Masses

2009/9/4
Conventional equilibrium statistical mechanics of open gravitational systems is known to be problematical. We first recall that spherical stars/galaxies acquire unbounded radii, become infinitely mass...
