We present new radio observations of the binary neutron star merger GW170817 carried out
with the Karl G. Jansky Very large Array (VLA) more than 3 yr after the merger. Our …

Since the gravitational wave event GW170817 and gamma-ray burst GW170817A, there
have been numerous studies constraining the burst properties through analysis of the …

A new component was reported in the X-ray counterpart to the binary neutron star merger
and gravitational-wave event GW170817, exceeding the afterglow emission from an off-axis …

A relativistic electron–positron (e+ e−) pair wind from a rapidly rotating, strongly magnetized
neutron star (NS) would interact with a gamma-ray burst (GRB) external shock and reshape …

We study the broad-band radiation behaviour of a kilonova ejecta-pulsar wind nebula
(PWN) system. In this model, we jointly fit the observations of AT 2017gfo in UV-optical-IR …

Short gamma-ray bursts and their afterglows can be produced during the merger of two
neutron stars. Combined electromagnetic and gravitational wave observations of compact …

The first detection of gravitational waves on 2015 with the Advanced LIGO and Advanced
Virgo interferometers has opened a new observational window in the Universe. The last …

Astrophysical transients are a class of variable sources often associated with some of the
most cataclysmic phenomena in the universe, such as compact object (neutron stars and …
