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…
Evidence of Energy Injection in the Short and Distant GRB 250221A in a High Density Environment
Camila Angulo-Valdez, Rosa L. Becerra, Ramandeep Gill +29
We present the photometric and spectroscopic analysis of the short-duration GRB 250221A ( s), using a data set from the optical facilities COLIBRÍ, the Harlingt…
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…
On the Efficiency of Producing Gamma-Ray Bursts from Isolated Population III Stars
Gibran Morales-Rivera, Ramandeep Gill, S. Jane Arthur +2
The rate of long-duration gamma-ray bursts (GRBs) from isolated Pop III stars is not well known, as it depends on our poor understanding of their initial mass function (IMF), rotat…
Continued Rapid Radio Brightening of the Tidal Disruption Event AT2018hyz
Yvette Cendes, Edo Berger, Paz Beniamini +15
We present ongoing radio observations of the tidal disruption event (TDE) AT2018hyz, which was first detected in the radio at 972 days after disruption, following multiple non-dete…
The curious case of EP241021a: Unraveling the mystery of its exceptional rebrightening
Malte Busmann, Brendan O'Connor, Julian Sommer +19
Fast X-ray Transients (FXTs) are a rare and poorly understood phenomenon with a variety of possible progenitors. The launch of the Einstein Probe (EP) mission has facilitated a rap…
