Delving Deeper into the Tumultuous Lives of Galactic Dwarfs: Modeling Star Formation Histories
Chris Orban, Oleg Y. Gnedin, Daniel R. Weisz +3
The paucity of observed dwarf galaxies in the Local Group relative to the abundance of predicted dark matter halos remains one of the greatest puzzles of the LCDM paradigm. Solving…
Dynamical Evolution of Globular Clusters in Hierarchical Cosmology
Oleg Y. Gnedin, Jose L. Prieto
We probe the evolution of globular clusters that could form in giant molecular clouds within high-redshift galaxies. Numerical simulations demonstrate that the large and dense enou…
Theory of cooling neutron stars versus observations
D. G. Yakovlev, O. Y. Gnedin, A. D. Kaminker +1
We review current state of neutron star cooling theory and discuss the prospects to constrain the equation of state, neutrino emission and superfluid properties of neutron star cor…
Velocity Dispersion Profiles of Seven Dwarf Spheroidal Galaxies
Matthew G. Walker, Mario Mateo, Edward W. Olszewski +4
We present stellar velocity dispersion profiles for seven Milky Way dwarf spheroidal (dSph) satellite galaxies. We have measured 8394 line-of-sight velocities (+/- 2.5 km/s) for 68…
The survival and disruption of CDM micro-haloes: implications for direct and indirect detection experiments
Tobias Goerdt, Oleg Y. Gnedin, Ben Moore +2
If the dark matter particle is a neutralino then the first structures to form are cuspy cold dark matter (CDM) haloes collapsing after redshifts z ~ 100 in the mass range 10^{-6} -…
Dark Matter Halos of Disk Galaxies: Constraints from the Tully-Fisher Relation
Oleg Y. Gnedin, David H. Weinberg, James Pizagno +2
We investigate structural properties of dark matter halos of disk galaxies in LCDM cosmology, using a well-defined sample of 81 disk-dominated galaxies from the SDSS redshift surve…
