Scientists monitoring black holes have announced that their laser labs have managed to sense and record strange ripples from a gargantuan collision that occurred in July 2017 when two large holes weighing more than 50-34 times the weight of sun united to produce a single large object that is now 80 times the mass of our sun star. The event occurred around five billion light years away from Earth and researchers from LIGO-VIRGO Collaboration have stated that three previous black hole mergers were missed during initial run- through of the data. The reanalysis of data available has brought the actual number of gravitational wave events to 11 of which 10 were black hole mergers and one was collision between remnants of dense star.
The black hole has emerged now due to data collation from three laser interferometer locations in Washington and Louisiana at United States and one at Pisa in Italy. These super-sensitive instruments listen for gravitational waves that emanate from cosmic events in outer space and recorded them between 2015 and 2017. This colossal data was run through algorithms to detect patterns related to gravitational waves and scientists often keep going back to reassess the data for more accurate results and patterns.
Prof Shane Larson from Northwestern University, a collaboration member of this information wrote on his blog that team members keep sifting through the data and compare it to their astrophysical predictions using super-computer analysis codes. This detailed search has led to the recent discovery of new black hole mergers while the latest discoveries came from data collected between Nov 2016 and August 2017. The hung for gravitational waves is for researchers to keep track of likely number of black holes that can be accommodated within specific volume of space. This data also tells us about probable success of laser laboratories in the future.
