A new model for studying activity around quasars

A new model for studying activity around quasars

Artistic interpretation demonstrates ULAS J1120 + 0641 - a distant quasar fueled from a black hole.

The new computer model is able to more accurately explain the diversity of areas of the quasi-emission line — a cloud of red-hot ionized gas concentrated around supermassive black holes in galactic centers.

Now scientists are trying to get more detailed information about the spectral broadband areas that help diagnose the massiveness of black holes. Most modern models consider symmetric lines in the spectral broad emission line of active galactic nuclei. However, the new model concentrates on real lines, which often appear asymmetrical.

The new model is aimed at explaining the entire spectrum of quasars. The black hole's gravity increases the velocity of the gas surrounding the quasars. Because of this, it heats up and clouds the galaxy. People have the wrong impression. They look at the hole and see that it is bright. In reality, it remains dark. But the disks reach so high temperatures that they release radiation in the EM spectrum, including gamma, UV, IR, X-rays and radio waves. Gases move at speeds of thousands of kilometers per second.

Each emission line has its own color, and together they create a whole spiral. The model shows how dust lumps move and merge. The study is important for the scientific world, because it allows a closer look at the emission lines that form the mass of black holes.
