First Observation of Time Variation in the Solar-Disk Gamma-Ray Flux with Fermi
Kenny C. Y. Ng, John F. Beacom, Annika H. G. Peter +1
The solar disk is a bright gamma-ray source. Surprisingly, its flux is about one order of magnitude higher than predicted. As a first step toward understanding the physical origin…
Dark Matter Velocity Spectroscopy
Eric G. Speckhard, Kenny C. Y. Ng, John F. Beacom +1
Dark matter decays or annihilations that produce line-like spectra may be smoking-gun signals. However, even such distinctive signatures can be mimicked by astrophysical or instrum…
Improved Limits on Sterile Neutrino Dark Matter using Full-Sky Fermi Gamma-Ray Burst Monitor Data
Kenny C. Y. Ng, Shunsaku Horiuchi, Jennifer M. Gaskins +2
A sterile neutrino of ~keV mass is a well motivated dark matter candidate. Its decay generates an X-ray line that offers a unique target for X-ray telescopes. For the first time, w…
Improved limits on sterile neutrino dark matter from full-sky observations by the Fermi-GBM
Shunsaku Horiuchi, Kenny C. Y. Ng, Jennifer M. Gaskins +2
For the first time, we use the Gamma-ray Burst Monitor (GBM) on-board the Fermi satellite to search for sterile neutrino decay lines in the energy range 10-25 keV corresponding to…
