WIMPs with Enhanced Annihilation from a Feebly Interacting Unstable Partner
Chance Hoskinson, Pearl Sandick, Barmak Shams Es Haghi
Weakly interacting massive particles (WIMPs) constitute one of the best-motivated dark matter (DM) candidates. In this study, we consider a simple extension of the WIMP paradigm in…
Constraints on the Injection of Radiation in the Early Universe
Melissa Joseph, Jason Kumar, Pearl Sandick
We consider the generic injection of radiation (both dark and electromagnetic) during the epoch between big bang nucleosynthesis (BBN) and recombination. The contribution of the ad…
A likelihood analysis for gamma-ray background models
Chance Hoskinson, Jason Kumar, Pearl Sandick
Indirect searches for dark matter using dwarf spheroidal galaxies are limited by systematic uncertainties in modeling diffuse gamma-ray backgrounds. We present a likelihood-based c…
Clustering with Light (but Massive) Relics
Jason Kumar, Pearl Sandick, Shuting Xu
We consider the effect of Light (but Massive) Relics (LiMRs) on the clustering of matter in the early Universe. We account for the fact that LiMRs which are massive enough may clus…
Can a Breakdown of Hawking Evaporation Open a New Mass Window for Primordial Black Holes as Dark Matter?
Gabriele Montefalcone, Dan Hooper, Katherine Freese +3
Semi-classical Hawking evaporation is expected to break down at some point in a black hole's evolution as the effects of quantum gravity become important. In particular, it has bee…
Indirect Detection of Hot Dark Matter
Jeff A. Dror, Pearl Sandick, Barmak Shams Es Haghi +1
Cosmologically stable, light particles that came into thermal contact with the Standard Model in the early universe may persist today as a form of hot dark matter. For relics with…
