The central slope of dark matter cores in dwarf galaxies: Simulations vs. THINGS
Galaxies dark matter halos – galaxies cosmological N-body+SPH simulations –galaxies kinematics and dynamics
2010/11/15
We make a direct comparison of the derived dark matter (DM) distributions between hydrody-
namical simulations of dwarf galaxies assuming a CDM cosmology and the observed dwarf galaxies sample from ...
Dwarf galaxies in the nearby Lynx-Cancer void: photometry, colours and ages
Dwarf galaxies photometry colours ages
2010/11/16
The nearby Lynx-Cancer void is a good laboratory to study the effect of very rarefied environment on the evolution of the least massive dwarf galaxies. A recently compiled sample of this void’s galaxi...
Faint dwarf galaxies in the Next Generation Virgo cluster Survey
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/6
The Next Generation Virgo Cluster Survey (NGVS) is a CFHT Large Program that is using the wide field of view capabilities of the MegaCam camera to map the entire Virgo Cluster from its core to virial ...
A census of ultra-compact dwarf galaxies in nearby galaxy clusters
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/5
Ultra-compact dwarf galaxies (UCDs) are predominatly found in the cores of nearby galaxy clusters. Besides the Fornax and Virgo cluster, UCDs have also been confirmed in the twice as distant Hydra I a...
The evolution of stellar structures in dwarf galaxies
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
We present a study of the variation of spatial structure of stellar populations within dwarf galaxies as a function of the population age. We use deep Hubble Space Telescope/Advanced Camera for Survey...
Nuclei of early-type dwarf galaxies: are they progenitors of UCDs?
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
To address the question of whether the so-called ultra compact dwarf galaxies (UCDs) are the remnant nuclei of destroyed early-type dwarf galaxies (dEs), we analyze the stellar population parameters o...
