Barry Clark Barish is an American born physicist and Nobel Laureate. He is a Professor of Physics, emeritus at CIT (California Institute of Technology). He is one of the leading experts on gravitational waves.
In 2017, Barish was awarded the Nobel Prize in Physics along with Rainer Weiss and Kip Thorne “for their contributions to the LIGO detector and the observation of gravitational waves
Barry C Barish married to Samoan Barish. They have two children, Stephanie Barish and Kenneth Barish, and three grandchildren, Milo Barish-Chamberlin, Thea Chamberlin, and Ariel Barish.
The initial LIGO detectors reached design sensitivity and set many limits on astrophysical sources. The Advanced LIGO proposal was developed while Barish was a director, and he has continued to play a leading role in LIGO and Advanced LIGO. The first detection of the merger of two 30 solar mass black holes was made on September 14, 2015. This represented the first direct detection of gravitational waves since they were predicted by Einstein in 1916 and the first ever observation of the merger of a pair of black holes. Barish delivered the first presentation on this discovery to a scientific audience at CERN on Feb 11, 2016, simultaneously with the public announcement.
