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…
Quasar clustering at redshift 6
J. Greiner, J. Bolmer, R. M. Yates +4
Large-scale surveys over the last years have revealed about 300 QSOs at redshift above 6. Follow-up observations identified surprising properties, such as the very high black hole…
Four GRB-Supernovae at Redshifts between 0.4 and 0.8
S. Klose, S. Schmidl, D. A. Kann +16
Twenty years ago, GRB 980425/SN 1998bw revealed that long Gamma-Ray Bursts (GRBs) are physically associated with broad-lined type Ic supernovae. Since then more than 1000 long GRBs…
The Optical/NIR afterglow of GRB 111209A: Complex yet not Unprecedented
D. A. Kann, P. Schady, F. Olivares E. +24
Afterglows of Gamma-Ray Bursts (GRBs) are simple in the most basic model, but can show many complex features. The ultra-long duration GRB 111209A, one of the longest GRBs ever dete…
Highly Luminous Supernovae associated with Gamma-Ray Bursts I.: GRB 111209A/SN 2011kl in the Context of Stripped-Envelope and Superluminous Supernovae
D. A. Kann, P. Schady, F. E. Olivares +22
GRB 111209A, one of the longest Gamma-Ray Bursts (GRBs) ever observed, is linked to SN 2011kl, the most luminous GRB-Supernova (SN) detected so far, which shows evidence for being…
A very luminous magnetar-powered supernova associated with an ultra-long gamma-ray burst
Jochen Greiner, Paolo A. Mazzali, D. Alexander Kann +29
A new class of ultra-long duration (>10,000 s) gamma-ray bursts has recently been suggested. They may originate in the explosion of stars with much larger radii than normal long ga…
