Russian Researchers Discover 11 New Active Galactic Nuclei
Scientists in Russia have found 11 new super bright objects called active galactic nuclei (AGNs) in space.
These AGNs are like giant lighthouses, shining with lots of energy from the centers of galaxies where giant black holes live.
The scientists used a special telescope in space to find them.
They found different types of AGNs, like Seyfert galaxies.
These new AGNs are located relatively close to us in space.
Studying these objects helps scientists learn more about how galaxies work and understand the universe better.
One of the AGNs has a strong absorption that is reflected from the galaxy's dusty areas.
Russian researchers discovered 11 new active galactic nuclei (AGNs) using the Spektr-RG X-ray survey.
The AGNs were identified by the ART-XC telescope of the Spektr-RG space observatory.
The newly discovered AGNs are classified as Seyfert galaxies: seven type 1, three type 1.9, and one type 2.
These AGNs are located relatively nearby, at redshifts of 0.028-0.258.
The X-ray luminosities of the sources range from 2 to 300 tredecillion erg/s.
