A multi-wavelength analysis of a collection of short-duration GRBs observed between 2012-2015
S. B. Pandey, Y. Hu, A. J. Castro-Tirado +71
We investigate the prompt emission and the afterglow properties of short duration gamma-ray burst (sGRB) 130603B and another eight sGRB events during 2012-2015, observed by several…
Photometric Observations of Supernova 2013cq Associated with GRB 130427A
R. L. Becerra, A. M. Watson, W. H. Lee +18
We observed the afterglow of GRB 130427A with the RATIR instrument on the 1.5-m Harold L. Johnson telescope of the Observatorio Astronómico Nacional on Sierra San Pedro Mártir. Our…
ALMA and RATIR observations of GRB131030A
Kuiyun Huang, Yuji Urata, Satoko Takahashi +22
We report on the first open-use based Atacama Large Millimeter/submm Array (ALMA) 345-GHz observation for the late afterglow phase of GRB131030A. The ALMA observation constrained a…
Happy Birthday Swift: Ultra-long GRB141121A and its broad-band Afterglow
A. Cucchiara, P. Veres, A. Corsi +27
We present our extensive observational campaign on the Swift-discovered GRB141121A, al- most ten years after its launch. Our observations covers radio through X-rays, and extends f…
The central engine of GRB 130831A and the energy breakdown of a relativistic explosion
M. De Pasquale, S. R. Oates, J. L. Racusin +37
Gamma-ray bursts (GRBs) are the most luminous explosions in the universe, yet the nature and physical properties of their energy sources are far from understood. Very important clu…
The Energy-Dependence of GRB Minimum Variability Timescales
V. Zach Golkhou, Nathaniel R. Butler, Owen M. Littlejohns
We constrain the minimum variability timescales for 938 GRBs observed by the Fermi/GBM instrument prior to July 11, 2012. The tightest constraints on progenitor radii derived from…
A detailed study of the optical attenuation of gamma-ray bursts in the Swift era
O. M. Littlejohns, N. R. Butler, A. Cucchiara +16
We present optical and near-infrared (NIR) photometry of 28 gamma-ray bursts (GRBs) detected by the \textit{Swift} satellite and rapidly observed by the Reionization and Transients…
Investigating signatures of cosmological time dilation in duration measures of prompt gamma-ray burst light curves
O. M. Littlejohns, N. R. Butler
We study the evolution with redshift of three measures of gamma-ray burst (GRB) duration (, and ) in a fixed rest frame energy band for a samp…
Identifying high-redshift GRBs with RATIR
O. M. Littlejohns, N. R. Butler, A. Cucchiara +16
We present a template fitting algorithm for determining photometric redshifts, , of candidate high-redshift gamma-ray bursts (GRBs). Using afterglow photometry, obtai…
Multiwavelength observations of GRB 110731A: GeV emission from onset to afterglow
LAT Collaboration, GBM Collaboration, Swift Collaboration +2
We report on the multiwavelength observations of the bright, long gamma-ray burst \GRB, by the \Fermi and \Swift observatories, and by the MOA and GROND optical telescopes. The ana…
The origin of the early time optical emission of Swift GRB 080310
O. M. Littlejohns, R. Willingale, P. T. O'Brien +28
We present broadband multi-wavelength observations of GRB 080310 at redshift z = 2.43. This burst was bright and long-lived, and unusual in having extensive optical and near IR fol…
