TeV Solar Gamma Rays From Cosmic-Ray Interactions
Bei Zhou, Kenny C. Y. Ng, John F. Beacom +1
The Sun is a bright source of GeV gamma rays, due to cosmic rays interacting with solar matter and photons. Key aspects of the underlying processes remain mysterious. The emission…
An observer's guide to the (Local Group) dwarf galaxies: predictions for their own dwarf satellite populations
Gregory A. Dooley, Annika H. G. Peter, Tianyi Yang +3
A recent surge in the discovery of new ultrafaint dwarf satellites of the Milky Way has inspired the idea of searching for faint satellites, $10^3\, \mathrm{M_{\odot}} < M_* < 10^6…
Hidden Sector Hydrogen as Dark Matter: Small-scale Structure Formation Predictions and the Importance of Hyperfine Interactions
Kimberly K. Boddy, Manoj Kaplinghat, Anna Kwa +1
We study the atomic physics and the astrophysical implications of a model in which the dark matter is the analog of hydrogen in a secluded sector. The self interactions between dar…
In the Wake of Dark Giants: New Signatures of Dark Matter Self Interactions in Equal Mass Mergers of Galaxy Clusters
Stacy Y. Kim, Annika H. G. Peter, David Wittman
Merging galaxy clusters have been touted as one of the best probes for constraining self-interacting dark matter, but few simulations exist to back up this claim. We simulate equal…
First results from the MADCASH Survey: A Faint Dwarf Galaxy Companion to the Low Mass Spiral Galaxy NGC 2403 at 3.2 Mpc
Jeffrey L. Carlin, David J. Sand, Paul Price +13
We report the discovery of the faintest known dwarf galaxy satellite of an LMC stellar-mass host beyond the Local Group, based on deep imaging with Subaru/Hyper Suprime-Cam. MADCAS…
The connection between the host halo and the satellite galaxies of the Milky Way
Yu Lu, Andrew Benson, Yao-Yuan Mao +5
Many properties of the Milky Way's dark matter halo, including its mass assembly history, concentration, and subhalo population, remain poorly constrained. We explore the connectio…
