The evolution of dwarf galaxies in the Coma supercluster
galaxies clusters general galaxies clusters individual Coma galaxies dwarf
2010/11/10
We employ spectroscopic and photometric data from SDSS DR7, in a 500 square degree
region, to understand the evolution of dwarf (M+2 galaxies in the Coma
supercluster (z = 0.023). We show...
We develop a technique to investigate the possibility that some of the recently discovered ultra-faint dwarf satellites of the Milky Way might be cusp caustics rather than gravitationally self-bound s...
Groups of dwarf galaxies in the Local supercluster
Cosmology and Extragalactic Astrophysics (astro-ph.CO
2010/12/27
We present a project on study of groups composed of dwarf galaxies only. We selected such structures using HyperLEDA and NED databases with visual inspection on SDSS images and on digital copy of POSS...
How do dwarf galaxies acquire their mass & when do they form their stars?
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
We apply a simple, one-equation, galaxy formation model on top of the halos and subhalos of a high-resolution dark matter cosmological simulation to study how dwarf galaxies acquire their mass and, fo...
