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…

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…

Tools for probing new physics with newly discovered gamma-ray targets
Chance Hoskinson, Jason Kumar, Pearl Sandick
We present a computational tool, TweedleDEE, for empirically modeling diffuse gamma-ray background emission in a 1 degree region of the sky, using publicly available gamma-ray data…
