Telescope robots capture optical radiation from a record-high gamma-ray flash

Telescope robots recorded the optical radiation of a record-high gamma-ray flash. A study by scientists from Moscow State University is published in The Astrophysical Journal.

Gamma-ray burst is a very bright transformation of a fast-rotating star into a black hole. With such an outbreak, more energy is released in a few seconds than the sun can produce for its entire existence.

The global robotic network of “Master” telescopes, which was created by scientists at Moscow State University, recorded the optical radiation of the most powerful gamma-ray burst GRB 190114C on January 14, 2019 and measured its polarization. Of the eight network telescopes, two – located in the Canaries and in South Africa – almost instantly saw the light of a dying star.

“We managed to shoot the flash in four polarizing filters. On the whole, a thing unique in the history of optical astronomy happened: two telescopes located in different hemispheres of the planet were simultaneously aimed at one object. We dreamed about this for 17 years. In addition, this object is very short-lived (only a few minutes). This time we observed one of the most interesting gamma-ray bursts of the 21st century”.

Head of the Master network, professor at Moscow State University Vladimir Lipunov.

Since 2015, the “Master” has been constantly connected to the leading physical experiments of the world and responds to sources of gravitational waves, ultrahigh-energy neutrinos, fast radio bursts and gamma-ray bursts.
