Satellite Dwarf Galaxies in a Hierarchical Universe: Infall Histories, Group Preprocessing, and Reionization
Andrew R. Wetzel, Alis J. Deason, Shea Garrison-Kimmel
In the Local Group (LG), almost all satellite dwarf galaxies that are within the virial radius of the Milky Way (MW) and Andromeda (M31) exhibit strong environmental influence. The…
Cosmological Simulations of Decaying Dark Matter: Implications for Small-scale Structure of Dark Matter Halos
Mei-Yu Wang, Annika H. G. Peter, Louis E. Strigari +4
We present a set of N-body simulations of a class of models in which an unstable dark matter particle decays into a stable non-interacting dark matter particle, with decay lifetime…
Running with BICEP2: Implications for Small-Scale Problems in CDM
Shea Garrison-Kimmel, Shunsaku Horiuchi, Kevork N. Abazajian +2
The BICEP2 results, when interpreted as a gravitational wave signal and combined with other CMB data, suggest a roll-off in power towards small scales in the primordial matter powe…
Near-Field Limits on the Role of Faint Galaxies in Cosmic Reionization
Michael Boylan-Kolchin, James S. Bullock, Shea Garrison-Kimmel
Reionizing the Universe with galaxies appears to require significant star formation in low-mass halos at early times, while local dwarf galaxy counts tell us that star formation ha…
Too Big to Fail in the Local Group
Shea Garrison-Kimmel, Michael Boylan-Kolchin, James S. Bullock +1
We compare the dynamical masses of dwarf galaxies in the Local Group (LG) to the predicted masses of halos in the ELVIS suite of CDM simulations, a sample of 48 Galaxy-size host…
