Astronomers discover 'mystery object' in mass gap that could solve Black Holes puzzle
Astronomers found object in the"mass gap", a range between heaviest known neutron star and the lightest known black hole and created gravitational waves.

Scientists have discovered a mysterious astromical object merged with a black hole 780 million light-years away that could solve puzzle about black holes. object that sits right in "mass gap", a range between heaviest kwn neutron star and lightest kwn black hole and created gravitational waves which can be detected on Earth. In study published by American Astromical Society in open-access Astrophysical Journal on June 23, astromers revealed that new key findings of astromical object could help m resolve mystery of mystery behind black holes.
An object, 2.6 times mass of our sun merged with a black hole that was 23 times mass of our sun was found in mysterious gap, where stars h died and engulfed in black holes. Some of mass was blasted out as gravitational waves. object was recorded using gravitational wave detectors deployed by Laser Interferometer Gravitational-Wave Observatory, or LIGO, and Virgo were used to detect event. National Science Foundation's LIGO included two detectors — one in Livingston, Louisiana, and ar in Hanford, Washington. Virgo detector is located in Cascina, Italy.

cosmic merger described in study, an event dubbed GW190814 was going to change how scientists talk about neutron stars and black holes, a professor at University of Wisconsin and co-author Patrick Bry said.
Study’s authors Vicky Kalogera, and Daniel I. Linzer from university of physics and astromy at rthwestern University, said in a statement, “We've been waiting deces to solve this mystery.” "Mergers of a mixed nature — black holes and neutron stars — have been predicted for deces, but this compact object in mass gap is a complete surprise. We are really pushing our kwledge of low-mass compact objects," Kalogera said.

"Even though we can't classify object with conviction, we have seen eir heaviest kwn neutron star or lightest kwn black hole. Eir way, it breaks a record," said Kalogera, who is also director of rthwestern's Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA).

New light on a part of universe
When most massive stars die, y collapse under ir own gravity and leave behind black holes; when stars that are a bit less massive die, y explode in supervas and leave behind dense, de remnants of stars called neutron stars. For deces, astromers have been puzzled by a gap that lies between neutron stars and black holes, California University of Techlogy wrote in a report. Furr, it mentioned, that ripples from gravitational waves detected back on Earth by LIGO and Virgo in August 2019.

executive director of LIGO Laboratory at Caltech, David Reitze said, “Discoveries such as this are puzzles, and force us to scratch our hes a bit.” He ded, “Discerning true nature of this 'mass gap' object will require more observations, but those observations will undoubtedly shine new light on a part of universe that has previously been inaccessible to us."
