The new findings from the LIGO-Virgo team, that includes researchers from the Gravitational Wave group of the University of Birmingham's School of Physics and Astronomy, follows only a few months after the first direct detection of gravitational waves, ripples in the fabric of space-time, and the first observation of a binary black hole merger reported on 11 February 2016.
"Essentially, instead of searching the next section of sky that we would normally, we go off and observe some other area that has a higher probability of containing an optical counterpart of a gravitational wave event," said Eric Christensen, Catalina Sky Survey director and Lunar and Planetary Laboratory senior staff scientist.
Northwestern University's Shane Larson shares discoveries related to gravitational waves during "Songs from the Stellar Graveyard: Probing the Cosmos in Gravitational Waves" at 7 p.m.
The $30 million Advanced LIGO Plus (ALIGO+) project will improve the two existing Laser Interferometer Gravitational wave Observatories (LIGO) in the United States, and will be included as standard in the new LIGO India facility from the mid-2020s.
RIPPLES IN SPACETIME: Einstein, Gravitational Waves, and the Future of Astronomy
SCIENTISTS for the first time have detected both the ripples in space and time known as gravitational waves as well as light produced and emitted during the same cosmic event: the spectacular collision of two neutron stars.

It is already the fifth time LIGO has spotted a gravitational wave. But previously the ripples were from colliding black holes--and black holes don't give off light, making any optical observations of these cataclysms unlikely.
"This discovery ushers in a new era of astronomy where gravitational wave networks and traditional light-based astronomy will work hand-in-hand to uncover some of the universe's most prized secrets," Cardiff University said in a statement.
US scientists Rainer Weiss, Barry Barish and Kip Thorne won the 2017 NobelPrize for Physics for their pioneering role in the detection of gravitational waves, prize organisers said on Tuesday.
The gravitational wave emitted in the process was first detected by LIGO and its origin point was accurately pinpointed immediately.
