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…

Exploring the connection between compact object mergers and fast X-ray transients: The cases of LXT 240402A and EP250207b

R. L. Becerra, Yu-Han Yang, Eleonora Troja +29

The connection between compact object mergers and some extragalactic fast X-ray transients (FXRTs) has long been hypothesized, but never ultimately established. In this work, we in…

The soft X-ray transient EP241021a: A cosmic explosion with a complex off-axis jet and cocoon from a massive progenitor

Giulia Gianfagna, Luigi Piro, Gabriele Bruni +22

X-ray flashes (XRFs) are fast X-ray transients thought to be softer analogs of gamma-ray bursts (GRBs). With its soft X-ray sensitivity, the Einstein Probe (EP) provides a unique o…

Revealing characteristics of dark GRB 150309A: dust extinguished or high-z?

A. J. Castro-Tirado, Rahul Gupta, S. B. Pandey +28

Dark GRBs constitute a significant fraction of the GRB population. In this paper, we present the multiwavelength analysis of an intense two-episodic GRB 150309A observed early on t…

The Burst Observer and Optical Transient Exploring System in the multi-messenger astronomy era

Y. -D. Hu, E. Fernández-García, M. D. Caballero-García +6

The Burst Observer and Optical Transient Exploring System (BOOTES) was first designed as an asset of autonomous telescopes that started to be deployed in 1998, taking 24 years to b…
