Hunting for Dark Matter and New Physics with GECCO
Adam Coogan, Alexander Moiseev, Logan Morrison +9
We outline the science opportunities in the areas of searches for dark matter and new physics offered by a proposed future MeV gamma-ray telescope, the Galactic Explorer with a Cod…
Hazma Meets HERWIG4DM: Precision Gamma-Ray, Neutrino, and Positron Spectra for Light Dark Matter
Adam Coogan, Logan Morrison, Tilman Plehn +2
We present a new open-source package, Hazma 2, that computes accurate spectra relevant for indirect dark matter searches for photon, neutrino, and positron production from vector-m…
Kinetic recoupling of dark matter
Benjamin V. Lehmann, Logan Morrison, Stefano Profumo +1
We study the possibility that dark matter re-enters kinetic equilibrium with a radiation bath after kinetic decoupling, a scenario we dub kinetic recoupling. This naturally occurs,…
Simulation Based Inference for Efficient Theory Space Sampling: an Application to Supersymmetric Explanations of the Anomalous Muon (g-2)
Logan Morrison, Stefano Profumo, Nolan Smyth +1
For the purpose of minimizing the number of sample model evaluations, we propose and study algorithms that utilize (sequential) versions of likelihood-to-evidence ratio neural esti…
Hazma: A Python Toolkit for Studying Indirect Detection of Sub-GeV Dark Matter
Adam Coogan, Logan Morrison, Stefano Profumo
With several proposed MeV gamma-ray telescopes on the horizon, it is of paramount importance to perform accurate calculations of gamma-ray spectra expected from sub-GeV dark matter…
Precision Gamma-Ray Constraints for Sub-GeV Dark Matter Models
Adam Coogan, Logan Morrison, Stefano Profumo
The indirect detection of dark matter particles with mass below the GeV scale has recently received significant attention. Future space-borne gamma-ray telescopes, including All-Sk…
