Radioastron made the first map of the active galaxy — quasar

MOSCOW, October 4 — RIA Novosti. Russian space radio telescope "Radioastron" ("Spektr-R") for the first time mapped the active galaxy 0716 +714, was informed by the Astro Space Center of the Lebedev Physical Institute (LPI), Yuri Kovalyov, speaking at a conference at the Institute of Space Research, devoted to the 55th anniversary of the space age.

According to Kovalev, made the first map of the quasar — an active galaxy, the center of which is a supermassive black hole, which are ejected from the jet is very hot matter — jets.

"We first were able to measure the width of the nozzle jet — jet. It was approximately equal to 0.3 parsecs" — said the scientist. The brightness of the jet is two trillion kelvin, he added.

"This is the first image, the first card in the preparation of the project" Radioastron "- said Kovalev.

"In March, we conducted the first experiment on the mapping of the quasar 0716 +714, it is very variable. But at the time of the observations he had" decided "to reduce the power," — said Kovalev.

This summer it was reported that due to the "radio astronomer" astrophysicists could learn the sizes of the compact nucleus of the galaxy 0716 +714.

Quasars are among the brightest objects in the universe. According to one hypothesis, they are galaxies in the initial stage of development in which a supermassive black hole swallows the surrounding material.

Observatory "Radioastronlaunched from the Baikonur cosmodrome in July 2011, was the first in many years, space astrophysical tool created by Russian specialists. The radio telescope is designed to work in conjunction with a global network of ground-based radio telescopes, forming a single ground-space very long baseline interferometry (VLBI) is very high angular resolution — up to seven microseconds.

In November 2011, scientists conducted the first observations in an interferometer — "Radioastron" is paired with Russian telescopes Institute of Applied Astronomy, Ukrainian telescope in Evpatoria, German telescope in Effelsberg (Institute of Radio Astronomy Max Planck Society). In January 2012, "Radioastron" spent observing in conjunction with ground-based radio telescopes at the farthest point of its orbit, creating a virtual telescope with a mirror diameter of a record — 220,000 miles.
