Early Optical Follow-up of Gamma-Ray Bursts: The Critical Role of Robotic Telescopes
Rahul Gupta, Judith Racusin, Gor Oganesyan +26
Gamma-ray bursts (GRBs) are the most luminous electromagnetic explosions in the Universe, and offer unique laboratories for studying relativistic jets, compact-object formation, pa…
A Universal Physics Defining the Radiation Spectra of Blazars and Gamma-Ray Bursts
Z. Lucas Uhm, Sang-Sung Lee, Bing Zhang +5
Blazars and gamma-ray bursts (GRBs) are both cosmic beacons of extreme energy release powered by relativistic jets. However, they originate from tremendously different environments…
Foundations for Discovery: A Coordinated Fleet Approach to NASA Astrophysics
Regina Caputo, Francesca M. Civano, Knicole D. Colón +15
This white paper presents an analysis of Astro2020 science priorities and NASA's future astrophysics mission architecture, advocating for a coordinated fleet of $1--2B missions, s…
Episode-wise spectro-polarimetry of GRB 220107A: Testing the hypothesis of evolving radiation mechanisms
Rahul Gupta, Rushikesh Sonawane, Shabnam Iyyani +17
We investigate the spectro-polarimetric properties of the long-duration GRB~220107A, which exhibited two distinct emission episodes separated by a 40 s quiescent gap, to test wheth…
