Scientists have discovered 39 gravitational wave events, which they say will further help them understand the universe and explore the number of black holes and neutron stars. The latest event has been added to the 11 confirmed events, bringing the total number of events to 50. According to astrophysicists, this may be due to LIGO (American Laser Interferometer Gravity Wave Observatory) and Virgo (in Italy) Observatory. From April 1st to October 1st, 2019, these 39 things happened.
Scientists proposed GWTC-2, the “Gravitational Wave Transient Catalog 2”, which contains information about the detection of gravitational waves by LIGO and the Virgo Observatory. These waves are the result of events such as large-scale collisions between black holes and neutron stars. Astrophysicists have been observing these waves since 2015, making the latest 39 observations during the first half of the third observation period (called O3a). After LIGO and the Virgo Observatory were upgraded to powerful equipment, O3a will run from April 1st to October 1st, 2019.
According to the official statement, O3a has witnessed some interesting events, such as “the second gravitational wave observation that occurred when it merged with a binary neutron star, the first event with obviously unequal masses, and a very heavy black hole binary star with a total mass of about 150. Multiplied by the mass of the sun.” All these 50 observations have a wealth of information about the history and formation of black holes and neutron stars throughout the universe.
This information will help astrophysicists gain insight into the complexity of our universe. Scientists say that additional gravitational wave detection has also increased their understanding of general relativity. “The second part of O3 (called O3b) is currently being analyzed, which will further expand our growing catalog of gravitational wave transients. After O3, the probe will undergo further engineering improvements to make the fourth observation Increase the astrophysics detection range in time during operation.
