Planck Constraint on Relic Primordial Black Holes
Steven Clark, Bhaskar Dutta, Yu Gao +2
We investigate constraints on the abundance of primordial black holes (PBHs) in the mass range 10^{15}-10^{17} g using data from the Cosmic Microwave Background (CMB) and MeV extra…
Probing light mediators at ultra-low threshold energies with coherent elastic neutrino-nucleus scattering
James B. Dent, Bhaskar Dutta, Shu Liao +3
Light neutral mediators, with mass GeV, are common features of extensions to the Standard Model (SM). Current astrophysical and terrestrial experiments have constraine…
Tidal features of classical Milky Way satellites in a CDM universe
M. -Y. Wang, Azadeh Fattahi, Andrew P. Cooper +6
We use the APOSTLE cosmological hydrodynamic simulations to examine the effects of tidal stripping on cold dark matter (CDM) sub haloes that host three of the most luminous Milky W…
Searching for Dark Matter Annihilation in Recently Discovered Milky Way Satellites with Fermi-LAT
The Fermi-LAT, DES Collaborations, A. Albert +70
We search for excess gamma-ray emission coincident with the positions of confirmed and candidate Milky Way satellite galaxies using 6 years of data from the Fermi Large Area Telesc…
Farthest Neighbor: The Distant Milky Way Satellite Eridanus II
T. S. Li, J. D. Simon, A. Drlica-Wagner +56
We present Magellan/IMACS spectroscopy of the recently-discovered Milky Way satellite Eridanus II (Eri II). We identify 28 member stars in Eri II, from which we measure a systemic…
Nearest Neighbor: The Low-Mass Milky Way Satellite Tucana III
J. D. Simon, T. S. Li, A. Drlica-Wagner +56
We present Magellan/IMACS spectroscopy of the recently discovered Milky Way satellite Tucana III (Tuc III). We identify 26 member stars in Tuc III, from which we measure a mean rad…
