Updated Constraints on Asteroid-Mass Primordial Black Holes as Dark Matter
Nolan Smyth, Stefano Profumo, Samuel English +3
Microlensing of stars places significant constraints on sub-planetary-mass compact objects, including primordial black holes, as dark matter candidates. As the lens' Einstein radiu…
Uncovering Extremely Metal-Poor Stars in the Milky Way's Ultra-Faint Dwarf Spheroidal Satellite Galaxies
Evan N. Kirby, Joshua D. Simon, Marla Geha +2
We present new metallicity measurements for 298 individual red giant branch stars in eight of the least luminous dwarf spheroidal galaxies (dSphs) in the Milky Way (MW) system. Our…
The DEEP2 Redshift Survey: Lyman Alpha Emitters in the Spectroscopic Database
Marcin Sawicki, Brian C. Lemaux, Puragra Guhathakurta +7
We present the first results of a search for Lyman-alpha emitters (LAEs) in the DEEP2 spectroscopic database that uses a search technique that is different from but complementary t…
Was the Andromeda Stream Produced by a Disk Galaxy?
Mark A. Fardal, Arif Babul, Puragra Guhathakurta +2
The halo region of M31 exhibits a startling level of stellar inhomogeneities, the most prominent of which is the "giant southern stream". Our previous analysis indicates that this…
