The emission was from the compact merger
Long-term star mergers and merger effects of LIGO/Virgo have been studied in a series of galaxies with long-term GRBs. These galaxies contain stellar populations that appear to have redshifts and stellar population properties that are similar to those of GRBs. This study demonstrates the effects of these mergers on the physical properties of the GRBs’…

A kilo nova after a long-duration gamma-ray burst
Scientists have discovered a kilonova-like star about 1,000 times more massive than the Sun. This star was discovered by observing gravitational waves caused by the merger of two neutron stars, LIGO GW170817 and Virgo GW170817. Researchers said it is one of the last remnants of a dying neutron star, which was destroyed by a “supernova”…

A kilo nova following a burst of high-energy particles.
A study of the electromagnetic counterpart of binary neutron star mergers LIGO/Virgo GW170817 and GRB 1701718A and GRB 211211A has been conducted. The electromagnetic counterpart reflects the observations of GRB 211211A and LIGO/Virgo GW170817. A study of the spectral evolution of GRB X-ray tails has been conducted. In addition, a study of the shape of…
