Astrophysicists have found the “heartbeat” of a black hole

Astrophysicists talked about the discovery of gamma radiation, which is emitted from the microquasar SS 43. Scientists observe the interaction between such different and distant objects for the first time.

Astronomers have discovered mysterious ultra-bright flares at a distance of 15 thousand light-years from Earth. They become brighter once every 162 days, which is synchronized with the rotation of the black hole, which is part of the SS 43 microquasar. This may mean that there is a connection between these objects. If astronomers succeed in proving this, it will affect the study of other fundamental cosmic processes.

The researchers noted that the design of these flares “defies obvious interpretations and is unexpected based on previously published theoretical models”. In their opinion, “SS 433 will continue to amaze astronomers in the future”.

“Material, before falling into the black hole, accumulates in the accretion disk, like water in a whirlpool above a bathtub drain. But part of this substance does not fall there but shoots in the opposite direction. Perhaps this is the explanation for the origin of these outbreaks”

Previously, scientists observed such processes only for quasars with black holes in the millions of solar masses at their centers; while they throw jets tens of thousands of light-years into space. In the case of SS 433, scientists have recorded for the first time-periodic gamma radiation emitted by a microquasar.

Astronomers already know that SS 433 consists of a giant star, about 30 times the mass of the Sun, and a black hole, 10 to 20 times the mass of the Sun, that sucks the material out of the giant star.

For further conclusions, scientists must build models and make observations. While they are forming a list of theories that will need to be confirmed or refuted.
