A milli-Tidal Disruption Event Model for GRB250702B: Main Sequence Star Disrupted by an IMBH
Jonathan Granot, Hagai B. Perets, Ramandeep Gill +2
GRB250702B is the longest GRB recorded so far, with multiple gamma-ray emission episodes spread over a duration exceeding ks and a weaker soft X-ray pre-peak day…
Synchrotron Self-Compton Model of TeV Afterglows in Gamma-Ray Bursts
Edilberto Aguilar-Ruiz, Ramandeep Gill, Paz Beniamini +1
The detection of a very-high-energy TeV spectral component in the afterglow emission of gamma-ray bursts (GRBs) has opened a new probe into the energetics of ultra-relativistic bla…
Comprehensive X-ray Observations of the Exceptional Ultra-long X-ray and Gamma-ray Transient GRB 250702B with Swift, NuSTAR, and Chandra: Insights from the X-ray Afterglow Properties
Brendan O'Connor, Ramandeep Gill, James DeLaunay +22
GRB 250702B is an exceptional transient that produced multiple episodes of luminous gamma-ray radiation lasting for ks, placing it among the class of ultra-long gamma-ray bur…
The redshift distribution of Einstein Probe transients supports their relation to gamma-ray bursts
Brendan O'Connor, Paz Beniamini, Eleonora Troja +9
The launch of the \textit{Einstein Probe} unleashed a new era of high-energy transient discovery in the largely unexplored soft X-ray band. The \textit{Einstein Probe} has detected…
GRB 250702B: Discovery of a Gamma-Ray Burst from a Black Hole Falling into a Star
Eliza Neights, Eric Burns, Chris L. Fryer +52
Gamma-ray bursts are the most luminous electromagnetic events in the universe. Their prompt gamma-ray emission has typical durations between a fraction of a second and several minu…
Optical/infrared observations of the extraordinary GRB 250702B: a highly obscured afterglow in a massive galaxy consistent with multiple possible progenitors
Jonathan Carney, Igor Andreoni, Brendan O'Connor +31
GRB 250702B was the longest gamma-ray burst ever detected, with a duration that challenges standard collapsar models and suggests an exotic progenitor. We collected a rich set of o…
