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.

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.

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.
An extremely luminous X-ray outburst at the birth of a supernova

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.

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…
Illuminating gravitational waves: A concordant picture of photons from a neutron star merger

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…
Detectable radio flares following gravitational waves from mergers of binary neutron stars
Results of calculations are presented showing that the interaction of mildly relativistic outflows with the surrounding medium produces radio flares with peak emission at 1.4 gigahertz that persist at detectable (submillijansky) levels for weeks, out to a redshift of 0.1.
