Failed jet breakout in the metal-poor broad-lined type Ic supernova 2026gzf
Antonio Martin-Carrillo, Christina C. Thöne, James K. Leung +103
A long-standing question in the death of massive stars is the role of relativistic jets. While many gamma-ray bursts and some fast X-ray transients seem to be associated with broad…

We present the results from multi-wavelength observations of a transient discovered during the follow-up of S191213g, a gravitational wave (GW) event reported by the LIGO-Virgo Col…
The interstellar medium in the environment of the supernova-less long-duration GRB 111005A
Aleksandra Leśniewska, M. J. Michałowski, P. Kamphuis +17
Long ( s) gamma ray bursts (GRBs) are associated with explosions of massive stars, although in three instances, supernovae (SNe) have not been detected, despite deep observatio…
A blast from the infant Universe: the very high-z GRB 210905A
A. Rossi, D. D. Frederiks, D. A. Kann +52
We present a detailed follow-up of the very energetic GRB 210905A at a high redshift of z = 6.312 and its luminous X-ray and optical afterglow. We obtained a photometric and spectr…
A multi-wavelength analysis of a collection of short-duration GRBs observed between 2012-2015
S. B. Pandey, Y. Hu, A. J. Castro-Tirado +71
We investigate the prompt emission and the afterglow properties of short duration gamma-ray burst (sGRB) 130603B and another eight sGRB events during 2012-2015, observed by several…
On the nature of the unusual transient AT 2018cow from HI observations of its host galaxy
Michał J. Michałowski, P. Kamphuis, J. Hjorth +23
Unusual stellar explosions represent an opportunity to learn about both stellar and galaxy evolution. Mapping the atomic gas in host galaxies of such transients can lead to an unde…
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…
Relativistic supernova 2009bb exploded close to an atomic gas cloud
Michał J. Michałowski, G. Gentile, T. Kruhler +19
The potential similarity of the powering mechanisms of relativistic SNe and GRBs allowed us to make a prediction that relativistic SNe are born in environments similar to those of…
Molecular gas masses of gamma-ray burst host galaxies
Michał J. Michałowski, A. Karska, J. R. Rizzo +14
We obtained CO(2-1) observations of seven GRB hosts with the APEX and IRAM 30m telescopes. We analysed these data together with all other hosts with previous CO observations. We ob…
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 supermassive black hole coincident with the luminous transient ASASSN-15lh
T. Krühler, M. Fraser, G. Leloudas +11
The progenitors of astronomical transients are linked to a specific stellar population and galactic environment, and observing their host galaxies hence constrains the physical nat…
A kilonova as the electromagnetic counterpart to a gravitational-wave source
S. J. Smartt, T. -W. Chen, A. Jerkstrand +118
Gravitational waves were discovered with the detection of binary black hole mergers and they should also be detectable from lower mass neutron star mergers. These are predicted to…
