Search for gravitational-wave signals associated with gamma-ray bursts during the second observing run of Advanced LIGO and Advanced Virgo
B. P. Abbott, R. Abbott, T. D. Abbott +1196
We present the results of targeted searches for gravitational-wave transients associated with gamma-ray bursts during the second observing run of Advanced LIGO and Advanced Virgo,…
Multi-waveform cross-correlation search method for intermediate-duration gravitational waves from gamma-ray bursts
Eric Sowell, Alessandra Corsi, Robert Coyne
Gamma-ray Bursts (GRBs) are flashes of gamma-rays thought to originate from rare forms of massive star collapse (long GRBs), or from mergers of compact binaries (short GRBs) contai…
The late-time afterglow evolution of long gamma-ray bursts GRB 160625B and GRB 160509A
Tuomas Kangas, Andrew S. Fruchter, S. Bradley Cenko +12
We present post-jet-break \textit{HST}, VLA and \textit{Chandra} observations of the afterglow of the long -ray bursts GRB 160625B (between 69 and 209 days) and GRB 160509A (bet…
Short GRB 160821B: a reverse shock, a refreshed shock, and a well-sampled kilonova
