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…

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…

Fermi and Swift Observations of GRB 190114C: Tracing the Evolution of High-Energy Emission from Prompt to Afterglow

M. Ajello, M. Arimoto, M. Axelsson +147

We report on the observations of gamma-ray burst (GRB) 190114C by the Fermi Gamma-ray Space Telescope and the Neil Gehrels Swift Observatory. The early-time observations reveal mul…

Fermi observations of the LIGO event GW170104

Melissa Pesce-Rollins, Nicola Omodei, Dan Kocevski +3

We present the \emph{Fermi} Gamma-ray Burst Monitor (GBM) and Large Area Telescope (LAT) observations of the LIGO binary black hole merger (BBH) event GW170104. No candidate electr…

The central engine of GRB 130831A and the energy breakdown of a relativistic explosion

M. De Pasquale, S. R. Oates, J. L. Racusin +37

Gamma-ray bursts (GRBs) are the most luminous explosions in the universe, yet the nature and physical properties of their energy sources are far from understood. Very important clu…

GRB 131014A: a Laboratory to Study the Thermal-Like and Non-Thermal Emissions in Gamma-Ray Bursts, and the new L-E relation

S. Guiriec, R. Mochkovitch, T. Piran +5

Evidence has been accumulated on the existence of a thermal-like component during the prompt phase of GRBs. This component, often associated with the GRB jet's photosphere, is usua…

An External Shock Origin of GRB

J. Michael Burgess, Damien Bégué, Felix Ryde +4

The prompt emission of the long, smooth, and single-pulsed gamma-ray burst, GRB , is analyzed under the guise of an external shock model. First, we fit the -ra…
