On the gamma-ray emission from the core of the Sagittarius dwarf galaxy

Addy J. Evans, Louis E. Strigari, Oskar Svenborn +5

We use data from the Large Area Telescope onboard the Fermi gamma-ray space telescope (Fermi-LAT) to analyze the faint gamma-ray source located at the center of the Sagittarius (Sg…

Interpretation of Radio Afterglows in the framework of the Standard Fireball and Energy Injection models

Delina Levine, Maria Dainotti, Nissim Fraija +3

Gamma-Ray Bursts (GRBs) are panchromatic, highly energetic transients whose energy emission mechanism is still debated. One of the possible explanations is the standard fireball mo…

The 100-month Swift catalogue of supergiant fast X-ray transients II. SFXT diagnostics from outburst properties

Romano P., Evans P. A., Bozzo E. +9

Supergiant Fast X-ray Transients (SFXT) are High Mass X-ray Binaries displaying X-ray outbursts reaching peak luminosities of 10 erg/s and spend most of their life in more q…

Nucleosynthesis in Outflows from Black Hole-Neutron Star Merger Disks With Full GRRMHD

Sanjana Curtis, Jonah M. Miller, Carla Frohlich +3

Along with binary neutron star mergers, the in-spiral and merger of a black hole and a neutron star is a predicted site of -process nucleosynthesis and associated kilonovae. For…

On the Anti-Correlation between Duration and Redshift in Gamma-ray Bursts

Nicole M. Lloyd-Ronning, Jarrett L. Johnson, Roseanne M. Cheng +4

For gamma-ray bursts (GRBs) with durations greater than two seconds (so-called long GRBs), the intrinsic prompt gamma-ray emission appears, on average, to last longer for bursts at…

The TeV Sun Rises: Discovery of Gamma rays from the Quiescent Sun with HAWC

A. Albert, R. Alfaro, C. Alvarez +89

We report the first detection of a TeV gamma-ray flux from the solar disk (6.3), based on 6.1 years of data from the High Altitude Water Cherenkov (HAWC) observatory. The 0.5--2…
