The mysterious optical afterglow spectrum of GRB140506A at z=0.889
J. P. U. Fynbo, T. Krühler, K. Leighly +40
Context. Gamma-ray burst (GRBs) afterglows probe sightlines to star-forming regions in distant star-forming galaxies. Here we present a study of the peculiar afterglow spectrum of…
Hubble diagrams of relativistic broad-lined type Ic supernovae
Zach Cano, Pall Jakobsson, Oli Pall Geirsson
This paper is a demonstration of how relativistic, broad-lined type Ic supernovae (SNe IcBL) can be used to constrain a value of the Hubble constant in the local universe ()…
Gamma-ray burst supernovae as standardizable candles
Z. Cano
A long-duration gamma-ray burst (GRB) marks the violent end of a massive star. GRBs are rare in the universe, and their progenitor stars are thought to possess unique physical prop…
A Trio of GRB-SNe: GRB 120729A, GRB 130215A / SN 2013ez and GRB 130831A / SN 2013fu
Z. Cano, A. de Ugarte Postigo, A. Pozanenko +62
We present optical and near-infrared (NIR) photometry for three gamma-ray burst supernovae (GRB-SNe): GRB 120729A, GRB 130215A / SN 2013ez and GRB 130831A / SN 2013fu. In the case…
Diversity of GRB energetics vs. SN homogeneity: supernova 2013cq associated with the gamma-ray burst 130427A
A. Melandri, E. Pian, V. D'Elia +26
Long-duration gamma-ray bursts (GRBs) have been found to be associated with broad-lined type-Ic supernovae (SNe), but only a handful of cases have been studied in detail. Prompted…
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…
