Hydrogen-poor superluminous stellar explosions
TLDR
Observations of a class of luminous supernovae whose properties cannot be explained by any of the following processes: radioactive decay of freshly synthesized elements, explosion shock in the envelope of a supergiant star, and interaction between the debris and slowly moving, hydrogen-rich circumstellar material.
Relativistic ejecta from X-ray flash XRF 060218 and the rate of cosmic explosions
TLDR
Radio and X-ray observations of XRF 060218 (associated with supernova SN 2006aj), the second-nearest GRB identified until now, are reported, showing that this event is a hundred times less energetic but ten times more common than cosmological GRBs.
Superluminal motion of a relativistic jet in the neutron-star merger GW170817
TLDR
Radio observations using very long-baseline interferometry find that the compact radio source associated with GW170817 exhibits superluminal apparent motion between 75 days and 230 days after the merger event, which breaks the degeneracy between the choked- and successful-jet cocoon models.
An extremely luminous X-ray outburst at the birth of a supernova
TLDR
This work reports the serendipitous discovery of a supernova at the time of the explosion, marked by an extremely luminous X-ray outburst, and attributes the outburst to the ‘break-out’ of the supernova shock wave from the progenitor star, and shows that the inferred rate of such events agrees with that of all core-collapse supernovae.
LSST Science Book, Version 2.0
A survey that can cover the sky in optical bands over wide fields to faint magnitudes with a fast cadence will enable many of the exciting science opportunities of the next decade. The Large Synoptic…
Short-hard gamma-ray bursts
Two types of gamma-ray bursts (GRBs) are observed: short-duration hard spectrum GRBs and long-duration soft spectrum GRBs. For many years long GRBs were the focus of intense research while the lack…
Illuminating gravitational waves: A concordant picture of photons from a neutron star merger
TLDR
It is demonstrated that merging neutron stars are a long-sought production site forging heavy elements by r-process nucleosynthesis, which is dissimilar to classical short gamma-ray bursts with ultrarelativistic jets.
The afterglow of GRB 050709 and the nature of the short-hard γ-ray bursts
The final chapter in the long-standing mystery of the γ-ray bursts (GRBs) centres on the origin of the short-hard class of bursts, which are suspected on theoretical grounds to result from the…
The Afterglow, Energetics, and Host Galaxy of the Short-Hard Gamma-Ray Burst 051221a
We present detailed optical, X-ray, and radio observations of the bright afterglow of the short gamma-ray burst 051221a obtained with Gemini, Swift XRT, and the Very Large Array, as well as optical…
Early Supernovae Light Curves Following the Shock Breakout
The first light from a supernova (SN) emerges once the SN shock breaks out of the stellar surface. The first light, typically a UV or X-ray flash, is followed by a broken power-law decay of the…
