GRB 190114C in the nuclear region of an interacting galaxy -- A detailed host analysis using ALMA, HST and VLT

A. de Ugarte Postigo, C. C. Thöne, S. Martın +28

GRB 190114C is the first GRB for which the detection of very-high energy emission up to the TeV range has been reported. It is still unclear whether environmental properties might…

The late-time radio behavior of GRB afterglows: testing the standard model

Tuomas Kangas, Andrew Fruchter

We examine a sample of 21 gamma-ray burst (GRB) afterglow light curves at radio frequencies, and compare them to the X-ray and/or optical properties of the afterglows and to the pr…

The Case for a High-Redshift Origin of GRB100205A

A. A. Chrimes, A. J. Levan, E. R. Stanway +15

The number of long gamma-ray bursts (GRBs) known to have occurred in the distant Universe (z greater than 5) is small (approx 15), however these events provide a powerful way of pr…

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

G. P. Lamb, N. R. Tanvir, A. J. Levan +31

We report our identification of the optical afterglow and host galaxy of the short-duration gamma-ray burst GRB 160821B. The spectroscopic redshift of the host is , making…

A Surprising Lack of Metallicity Evolution with Redshift in the Long Gamma-Ray Burst Host Galaxy Population

J. F. Graham, P. Schady, A. S. Fruchter

The number of long-duration Gamma Ray Burst (LGRB) host galaxies with measured metallicities and host masses has now grown to over one hundred, allowing us to investigate how the d…
