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…
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…
A long optical plateau in the afterglow of the Extended Emission short GRB 150424A: Evidence for energy injection by a magnetar?
F. Knust, J. Greiner, H. J. van Eerten +14
Short-duration GRBs with extended emission form a subclass of short GRBs, comprising about 15% of the short-duration sample. Afterglow detections of short GRBs are also rare (about…
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…
Soft X-ray absorption excess in gamma-ray burst afterglow spectra: Absorption by turbulent ISM
M. Tanga, P. Schady, A. Gatto +5
Two-thirds of long duration gamma-ray bursts (GRBs) show soft X-ray absorption in excess of the Milky Way. The column densities of metals inferred from UV and optical spectra diffe…
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…
Super-solar metallicity at the position of the ultra-long GRB130925A
P. Schady, T. Kruehler, J. Greiner +17
Over the last decade there has been immense progress in the follow-up of short and long GRBs, resulting in a significant rise in the detection rate of X-ray and optical afterglows,…
Microphysics and dynamics of the Gamma-Ray Burst 121024A
K. Varela, H. van Eerten, J. Greiner +28
Aims. The aim of the study is to constrain the physics of gamma-ray bursts (GRBs) by analysing the multi-wavelength afterglow data set of GRB 121024A that covers the full range fro…
Gamma-Ray Bursts Trace UV Metrics of Star Formation over 3 < z < 5
Jochen Greiner, Derek B. Fox, Patricia Schady +15
We present the first uniform treatment of long duration gamma-ray burst (GRB) host galaxy detections and upper limits over the redshift range 3<z<5, a key epoch for observational a…
GROND coverage of the main peak of Gamma-Ray Burst 130925A
J. Greiner, H. -F. Yu, T. Krühler +23
Prompt or early optical emission in gamma-ray bursts is notoriously difficult to measure, and observations of the dozen cases show a large variety of properties. Yet, such early em…
Simultaneous optical/gamma-ray observations of GRB 121217's prompt emission
J. Elliott, H. -F. Yu, S. Schmidl +20
Since the advent of the Swift satellite it has been possible to obtain precise localisations of GRB positions of sub-arcsec accuracy within seconds, facilitating ground-based robot…
Prompt emission of GRB 121217A from gamma-rays to the NIR
J. Elliott, H. -F. Yu, S. Schmidl +20
The mechanism that causes the prompt-emission episode of gamma-ray bursts (GRBs) is still widely debated despite there being thousands of prompt detections. The favoured internal s…
The Afterglow of GRB 130427A from 1 to 10^16 GHz
D. A. Perley, S. B. Cenko, A. Corsi +31
We present multiwavelength observations of the afterglow of GRB 130427A, the brightest (in total fluence) gamma-ray burst of the past 29 years. Optical spectroscopy from Gemini-Nor…
