Machine-Learning Enhanced Photometric Analysis of the Extremely Bright GRB 210822A
Camila Angulo-Valdez, Rosa L. Becerra, Margarita Pereyra +16
We present analytical and numerical models of the bright long GRB 210822A at . The intrinsic extreme brightness exhibited in the optical, which is very similar to other br…
Understanding the Nature of the Optical Emission in Gamma-Ray Bursts: Analysis from TAROT, COATLI, and RATIR Observations
R. L. Becerra, A. Klotz, J. L. Atteia +12
We collected the optical light curve data of 227 gamma-ray bursts (GRBs) observed with the TAROT, COATLI, and RATIR telescopes. These consist of 133 detections and 94 upper limits.…
Deciphering the unusual stellar progenitor of GRB 210704A
R. L. Becerra, E. Troja, A. M. Watson +16
GRB~210704A is a burst of intermediate duration (~s) followed by a fading afterglow and an optical excess that peaked about 7 days after the explosion. Its propert…
A structured jet explains the extreme GRB 221009A
B. O'Connor, E. Troja, G. Ryan +29
Long duration gamma-ray bursts (GRBs) are powerful cosmic explosions, signaling the death of massive stars. Among them, GRB 221009A is by far the brightest burst ever observed. Due…
Limits on the Electromagnetic Counterpart to S190814bv
Alan M. Watson, Nathaniel R. Butler, William H. Lee +11
We derive limits on any electromagnetic counterpart to the compact binary merger S190814bv, whose parameters are consistent with the merger of a black hole and a neutron star. We p…
Reverse Shock Emission Revealed in Early Photometry in the Candidate Short GRB 180418A
Rosa L. Becerra, Simone Dichiara, Alan M. Watson +14
We present observations of the possible short GRB 180418A in -rays, X-rays, and in the optical. Early optical photometry with the TAROT and RATIR instruments show a bright peak…
