The GROND gamma-ray burst sample. I. Overview and statistics
J. Greiner, T. Krühler, J. Bolmer +17
A dedicated gamma-ray burst (GRB) afterglow observing program was performed between 2007 and 2016 with GROND, a seven-channel optical and near-infrared imager at the 2.2m telescope…
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…
Supernovae SDSS Host Metallicity Catalog and Resulting Metallicity Distributions by SNe Type
John F. Graham
In support of ongoing projects we have compiled a database of supernovae with host metallicities determined from spectroscopy in the Sloan Digital Sky Survey (SDSS) which we are pr…
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…
GRB 151027B - large-amplitude late-time radio variability
J. Greiner, J. Bolmer, M. Wieringa +20
Deriving physical parameters from gamma-ray burst afterglow observations remains a challenge, even now, 20 years after the discovery of afterglows. The main reason for the lack of…
The environment of the SN-less GRB 111005A at z = 0.0133
M. Tanga, T. Krühler, P. Schady +5
The collapsar model has proved highly successful in explaining the properties of long gamma-ray bursts (GRBs), with the most direct confirmation being the detection of a supernova…
