Wavelet-Based Techniques for the Gamma-Ray Sky
Samuel D. McDermott, Patrick J. Fox, Ilias Cholis +1
We demonstrate how the image analysis technique of wavelet decomposition can be applied to the gamma-ray sky to separate emission on different angular scales. New structures on sca…
Modulation Effects in Dark Matter-Electron Scattering Experiments
Samuel K. Lee, Mariangela Lisanti, Siddharth Mishra-Sharma +1
One of the next frontiers in dark-matter direct-detection experiments is to explore the MeV to GeV mass regime. Such light dark matter does not carry enough kinetic energy to produ…
Evidence for Unresolved Gamma-Ray Point Sources in the Inner Galaxy
Samuel K. Lee, Mariangela Lisanti, Benjamin R. Safdi +2
We present a new method to characterize unresolved point sources (PSs), generalizing traditional template fits to account for non-Poissonian photon statistics. We apply this method…
Modelling the flux distribution function of the extragalactic gamma-ray background from dark matter annihilation
Michael R. Feyereisen, Shin'ichiro Ando, Samuel K. Lee
The one-point function (i.e., the isotropic flux distribution) is a complementary method to (anisotropic) two-point correlations in searches for a gamma-ray dark matter annihilatio…
