Eight new black hole binaries in the galaxy

Eight new black hole binaries in the galaxy

Astronomers at the Massachusetts Institute of Technology have discovered eight new black hole binaries in the Milky Way, known before linking satellite data with the new research tool “Echo Machine”, instead of the two systems that emit X-ray echoes. The black hole glows and echoes.

After comparing the echoes across the systems, the team was able to put together an overall picture of how the black hole formed during the cosmic explosion. They first observed that the black hole was subjected to a solid state, which produced a high-energy “photons” halo, and a jet of relative particles fired at almost the speed of light.

At a certain point, the researchers found that the black hole emits a high-energy flash before it can transition to a “soft” low-energy state. These discoveries could help explain how massive black holes in the center of the Milky Way can spit out particles across vast cosmic scales to form a galaxy. According to a study published in The Astrophysical.

“The role of black holes in the evolution of galaxies is a key question in modern astronomical physics,” said Irene Cara, an associate professor of physics at MIT. “Interestingly, black hole binaries appear to be very large, so by understanding the eruptions that occur in these small systems nearby, we can understand how similar eruptions in supermassive black holes affect the galaxies in which they live.”
