Searching for Dark Matter Sub-structure with HAWC
A. U. Abeysekara, A. Albert, R. Alfaro +75
Simulations of dark matter show a discrepancy between the expected number of Galactic dark matter sub-halos and how many have been optically observed. Some of these unseen satellit…
Very high energy particle acceleration powered by the jets of the microquasar SS 433
HAWC Collaboration, A. U. Abeysekara, A. Albert +104
SS 433 is a binary system containing a supergiant star that is overflowing its Roche lobe with matter accreting onto a compact object (either a black hole or neutron star). Two jet…
VERITAS and Fermi-LAT observations of new HAWC sources
VERITAS Collaboration, A. U. Abeysekara, A. Archer +280
The HAWC (High Altitude Water Cherenkov) collaboration recently published their 2HWC catalog, listing 39 very high energy (VHE; >100~GeV) gamma-ray sources based on 507 days of obs…
Constraints on Spin-Dependent Dark Matter Scattering with Long-Lived Mediators from TeV Observations of the Sun with HAWC
A. Albert, R. Alfaro, C. Alvarez +91
We analyze the Sun as a source for the indirect detection of dark matter through a search for gamma rays from the solar disk. Capture of dark matter by elastic interactions with th…
First HAWC Observations of the Sun Constrain Steady TeV Gamma-Ray Emission
A. Albert, R. Alfaro, C. Alvarez +92
Steady gamma-ray emission up to at least 200 GeV has been detected from the solar disk in the Fermi-LAT data, with the brightest, hardest emission occurring during solar minimum. T…
An Unexpectedly Small Emission Region Size Inferred from Strong High-Frequency Diffractive Scintillation in GRB 161219B
Kate D. Alexander, Tanmoy Laskar, Edo Berger +8
We present Karl G. Jansky Very Large Array radio observations of the long gamma-ray burst GRB 161219B () spanning GHz. The data exhibit unusual behavior, including…
