The first neutron star merger

A new era, of multi-messenger astronomy (combining gravitational waves, particles, photons), has been born today. LIGO/VIRGO plus 70 teams around the world announced the first detection of colliding neutron stars, which means that a gravitational wave detection (GW170817) triggered the observations using almost everything available (from gamma rays to radio wavelengths) that identify and follow […]

Gravitational waves detected

Today (February 11, 2016), Laser Interferometer Gravitational-Wave Observatory (LIGO) announced the first-ever detection of gravitational waves [1], opening a new era in Astronomy. The signal recorded by LIGO on September 14, 2015, is consistent with a black-hole merger of 36 and 29 solar masses – resulting in a black hole of 62 solar masses. The […]
