A Complete Spectroscopic Survey of the Milky Way satellite Segue 1: Dark matter content, stellar membership and binary properties from a Bayesian analysis
Gregory D. Martinez, Quinn E. Minor, James Bullock +3
We introduce a comprehensive analysis of multi-epoch stellar line-of-sight velocities to determine the intrinsic velocity dispersion of the ultrafaint satellites of the Milky Way.…
The Herschel-SPIRE Legacy Survey (HSLS): the scientific goals of a shallow and wide submillimeter imaging survey with SPIRE
Asantha Cooray, Steve Eales, Scott Chapman +247
A large sub-mm survey with Herschel will enable many exciting science opportunities, especially in an era of wide-field optical and radio surveys and high resolution cosmic microwa…
A Complete Spectroscopic Survey of the Milky Way Satellite Segue 1: The Darkest Galaxy
Joshua D. Simon, Marla Geha, Quinn E. Minor +9
We present the results of a comprehensive Keck/DEIMOS spectroscopic survey of the ultra-faint Milky Way satellite galaxy Segue 1. We have obtained velocity measurements for 98.2% o…
Sommerfeld Enhancements for Thermal Relic Dark Matter
Jonathan L. Feng, Manoj Kaplinghat, Hai-Bo Yu
The annihilation cross section of thermal relic dark matter determines both its relic density and indirect detection signals. We determine how large indirect signals may be in scen…
Observations of Milky Way Dwarf Spheroidal galaxies with the Fermi-LAT detector and constraints on Dark Matter models
LAT Collaboration, A. A. Abdo, M. Ackermann +160
We report on the observations of 14 dwarf spheroidal galaxies with the Fermi Gamma-Ray Space Telescope taken during the first 11 months of survey mode operations. The Fermi telesco…
Correcting velocity dispersions of dwarf spheroidal galaxies for binary orbital motion
Quinn E. Minor, Greg Martinez, James Bullock +2
We show that measured velocity dispersions of dwarf spheroidal galaxies from about 4 to 10 km/s are unlikely to be inflated by more than 20% due to the orbital motion of binary sta…
