"The new exploration of the Universe through gravitational-wave observations"


The experiments to develop gravitational-wave detectors have recently become observatories able to detect transient gravitational-wave signals. This led to ground-breaking discoveries, which started on September 14, 2015, with the first detection of gravitational waves from the coalescence of a binary system of black holes by the Advanced LIGO detectors. Another epochal discovery happened on August 17, 2017, with the first observations of gravitational waves from the inspiral and merger of a binary neutron-star system by the Advanced LIGO and Virgo network, followed 1.7 s later by a weak short gamma-ray burst detected by the Fermi and INTEGRAL satellites. A world-wide observing campaign involving about 100 instruments led to the detection of multi-wavelength electromagnetic signals associated with this event. A new exploration of the most energetic transients in the sky started. The talk will give an overview of the recent gravitational-wave and multi-messenger observations, their astrophysical implications and the prospects for the upcoming years.
