We present a detailed report of the connection between long‐duration gamma‐ray bursts
(GRBs) and their accompanying supernovae (SNe). The discussion presented here places …

In recent years, our understanding of gamma‐ray bursts (GRB) prompt emission has been
revolutionized, due to a combination of new instruments, new analysis methods, and novel …

We present the first extensive radio to γ-ray observations of a fast-rising blue optical
transient, AT 2018cow, over its first∼ 100 days. AT 2018cow rose over a few days to a peak …

In the past decade, several rapidly evolving transients have been discovered whose
timescales and luminosities are not easily explained by traditional supernovae (SNe) …

Well before the afterglow era, Paczynski (1986) noted that “cosmological” distances of GRBs
would imply that the energy release in gamma rays would be comparable to the energy …

The bolometric properties (nickel mass, ejecta mass and kinetic energies) of 61 Ibc
supernovae (SNe), including 20 gamma-ray burst and X-ray flash (GRB/XRF), 19 Ib, 13 Ic …

Context. At low redshift, a handful of gamma-ray bursts (GRBs) have been discovered with
luminosities that are substantially lower (L iso≲ 10 48.5 erg s-1) than the average of more …

We present the spectroscopic and photometric evolution of the nearby (z= 0.059)
spectroscopically confirmed Type Ic supernova, SN 2010bh, associated with the soft, long …

In this work we present spectra of all γ-ray burst (GRB) afterglows that have been promptly
observed with the X-shooter spectrograph until 31/03/2017. In total, we have obtained …

We systematically compare the temporal and spectral properties of 53 supernova (SN)-
associated and 15 kilonova (KN)-associated gamma-ray bursts (GRBs). We find that the …
