One of the greatest mysteries of the Software reveals universe is black holes. They are captivating because of how much is unknown, but since gravitational waves caused by the merger of two black holes were detected more than eight years ago, a new window to the universe has opened and scientists have had the possibility of understanding a little about the origins of black holes.
Thanks to the significant advances made by the Posydon code in simulating binary star populations, an international team of scientists led by the University of Geneva and with the participation of the Institute of Space Sciences, the Institute for Space Studies of Catalonia, the University of Northwestern and the University of Florida predicted the existence of binary black holes of 30 solar masses in galaxies similar to the Milky Way, challenging previous theories.
The scientific work has been published by the journal Nature Astronomy and has used this Posydon software for the first time to investigate the merger of binary black holes, providing new insights into the formation mechanisms of black hole mergers in galaxies such as the Milky Way.
But what are stellar-mass black holes?
They are celestial objects that are born from the collapse of stars that have masses up to hundreds of times the mass of our sun. Their gravitational field is so intense that neither matter nor radiation can evade them, making them difficult to detect.
So the detection of waves produced Job Function by the merger of two black holes in 2015 by the Laser Interferometry Gravitational-waves Observatory (LIGO) was a turning point in this matter. According to the team, the two black holes that merged at the origin of the signal were about 30 times the mass of the Sun and were located 1.5 billion light-years away.
But there are still many unanswered
Questions surrounding black holes, such as what mechanisms produce these black holes, whether they are the product of the evolution of two stars, similar to our Sun but significantly more massive, evolving within a binary system, or whether they are the result of black holes in densely populated star clusters meeting by chance. Also still unanswered is whether this could be linked to a more exotic mechanism.
Black holes are still a mystery, but scientists seem determined to solve the mystery and have taken a step further in their work.
Posydon software is helping to provide Thailand Email List more accurate answers and reconcile theoretical predictions with observational data.
Simone Bavera, lead author of the study, said in a statement that “since it is impossible to directly observe the formation of binary black holes when they merge, it is necessary to rely on simulations that reproduce their observational properties,” adding that “we do this by simulating binary star systems from their birth to the formation of binary black hole systems.”
Bavera also highlighted that Posydon’s ability to “delve deeper into the formation and evolution of binary black hole mergers gives us hope for interpreting future observations of gravitational waves.”
Konstantinos , a researcher at the Institute of Space Sciences, said that “it provides a framework for understanding the physics of massive stars, whether isolated or part of a binary system, and their fascinating manifestations, such as X-ray binaries, type Ia supernovae, gamma-ray exposures and more.”
