TeV Solar Gamma Rays From Cosmic-Ray Interactions
Bei Zhou, Kenny C. Y. Ng, John F. Beacom +1
The Sun is a bright source of GeV gamma rays, due to cosmic rays interacting with solar matter and photons. Key aspects of the underlying processes remain mysterious. The emission…
The ASAS-SN Bright Supernova Catalog II. 2015
T. W. -S. Holoien, J. S. Brown, K. Z. Stanek +41
This manuscript presents information for all supernovae discovered by the All-Sky Automated Survey for SuperNovae (ASAS-SN) during 2015, its second full year of operations. The sam…
Testing decay of astrophysical neutrinos with incomplete information
Mauricio Bustamante, John F. Beacom, Kohta Murase
Neutrinos mix and have mass differences, so decays from one to another must occur. But how fast? The best direct limits on non-radiative decays, based on solar and atmospheric neut…
(Almost) Closing the MSM Sterile Neutrino Dark Matter Window with NuSTAR
Kerstin Perez, Kenny C. Y. Ng, John F. Beacom +3
We use NuSTAR observations of the Galactic Center to search for X-ray lines from the radiative decay of sterile neutrino dark matter. Finding no evidence of unknown lines, we set l…
Echo Technique to Distinguish Flavors of Astrophysical Neutrinos
Shirley Weishi Li, Mauricio Bustamante, John F. Beacom
The flavor composition of high-energy astrophysical neutrinos is a rich observable. However, present analyses cannot effectively distinguish particle showers induced by versu…
The Unexpected, Long-Lasting, UV Rebrightening of the Super-Luminous Supernova ASASSN-15lh
D. Godoy-Rivera, K. Z. Stanek, C. S. Kochanek +11
Given its peak luminosity and early-time spectra, ASASSN-15lh was classified as the most luminous supernova (SN) ever discovered (Dong et al. 2016). Here we report a UV rebrighteni…
