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…
Large Language Model-driven Analysis of General Coordinates Network (GCN) Circulars
Vidushi Sharma, Ronit Agarwala, Judith L. Racusin +9
The General Coordinates Network (GCN) is NASA's time-domain and multimessenger alert system. GCN distributes two data products: automated "Notices" and human-generated "Circulars"…
Extremely luminous optical afterglow of an energetic gamma-ray burst GRB 230204B
Rahul Gupta, Judith Racusin, Vladimir Lipunov +47
Robotic telescope networks play an important role in capturing early and bright optical afterglows, providing critical insights into the energetics and emission mechanisms of GRBs.…
Investigating Temporal Features in Swift GRB Afterglows: A Comparative Study of UVOT and XRT Data
Amit K. Ror, S. B. Pandey, S. R. Oates +4
This study presents a statistical analysis of optical light curves (LCs) of 200 UVOT-detected GRBs from 2005 to 2018. We have categorised these LCs based on their distinct morpholo…
Search for the Optical Counterpart of Einstein Probe Discovered Fast X-ray Transients from Lulin Observatory
Amar Aryan, Ting-Wan Chen, Sheng Yang +24
The launch of the Einstein Probe (EP) mission has revolutionized the detection and follow-up observations of fast X-ray transients (FXTs) by providing prompt and timely access to t…
Deciphering the Physical Origin of GRB 240825A: A Long GRB Lacking a Bright Supernova
Rahul Gupta, Judith L. Racusin, R. Sanchez-Ramirez +52
We present a comprehensive multiwavelength analysis of GRB 240825A, a bright gamma-ray burst (GRB) detected by Fermi and Swift, with a prompt duration ( ~ 4 sec in 50-3…
