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 luminous host galaxy, faint supernova and rapid afterglow rebrightening of GRB 100418A

A. de Ugarte Postigo, C. C. Thoene, K. Bensch +35

Long gamma-ray bursts give us the chance to study both their extreme physics and the star-forming galaxies in which they form. GRB 100418A, at a z = 0.6239, had a bright optical an…

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…

Multiwavelength analysis of three SNe associated with GRBs observed by GROND

F. Olivares E., J. Greiner, P. Schady +14

After the discovery of the first connection between GRBs and SNe almost two decades ago, tens of SN-like rebrightenings have been discovered and about seven solid associations have…

Blazar candidates beyond redshift 4 observed by Swift

T. Sbarrato, G. Ghisellini, G. Tagliaferri +4

We have selected SDSS J222032.50+002537.5 and SDSS J142048.01+120545.9 as best blazar candidates out of a complete sample of extremely radio-loud quasars at z>4, with highly massiv…

GRB 120422A/SN 2012bz: Bridging the Gap between Low- And High-Luminosity GRBs

S. Schulze, D. Malesani, A. Cucchiara +62

At low redshift, a handful of gamma-ray bursts (GRBs) have been discovered with peak luminosities () substantially lower than the average…
