Multi-band analyses of the bright GRB 230812B and the associated SN2023pel
T. Hussenot-Desenonges, T. Wouters, N. Guessoum +109
GRB~230812B is a bright and relatively nearby () long gamma-ray burst (GRB) that has generated significant interest in the community and has thus been observed over the en…
A blast from the infant Universe: the very high-z GRB 210905A
A. Rossi, D. D. Frederiks, D. A. Kann +52
We present a detailed follow-up of the very energetic GRB 210905A at a high redshift of z = 6.312 and its luminous X-ray and optical afterglow. We obtained a photometric and spectr…
The Broad-band Counterpart of the Short GRB 200522A at : A Luminous Kilonova or a Collimated Outflow with a Reverse Shock?
W. Fong, T. Laskar, J. Rastinejad +20
We present the discovery of the radio afterglow and near-infrared (NIR) counterpart of the Swift short GRB 200522A, located at a small projected offset of kpc from the…
Evidence for a Bright-Edged Jet in the Optical/NIR Afterglow of GRB 160625B
Robert Strausbaugh, Nathaniel Butler, William H. Lee +2
Using deep and high-cadence gamma-ray burst (GRB) afterglow data from RATIR, we observe a sharp and achromatic light curve break 12.6 days after the GRB, accompanied by an approxim…
RATIR Followup of LIGO/Virgo Gravitational Wave Events
V. Zach Golkhou, Nathaniel R. Butler, Robert Strausbaugh +5
Recently we have witnessed the first multi-messenger detection of colliding neutron stars through Gravitational Waves (GWs) and Electromagnetic (EM) waves (GW170817), thanks to the…
Ionized Reflection Spectra from Accretion Disks Illuminated by X-ray Pulsars
D. R. Ballantyne, J. D. Purvis, R. G. Strausbaugh +1
X-ray reflection signatures are observed around multiple classes of accreting compact objects. Modelling these features yield important constraints on the physics of accretion disk…
