Observations of galactic jellyfish helped find a new feeding method for central monsters. The principle of creating "tentacles" manages to reach the galactic center and feed the internal holes. The picture shows the galaxy JO204, taken by the Very Large Telescope. You see the material coming out of the galaxy to the left. Red is the ionized gaseous hydrogen, and the white areas are the cluster of most stars.
Scientists used the MUSE instrument on the Very Large Telescope to track the gas outflow from the galaxy. They focused on the “jellyfish” forms, which are called so because of the tentacles of the material, stretching for tens of thousands of light years.
Tentacles appear due to depressurization of pressure. Mutual gravity in clusters causes galaxies to fall and collide with a high-density hot gas. Studies have shown that 6 out of 7 galaxies have supermassive black holes that are fed by gas jets. And this is a high figure. Previously, never suspected about the relationship of the pressure drop and the activity of black holes. For many years they doubted their awakening. They are noticeable in all large galaxies, but the glow is noted only in rare cases. Why? Scientists have found a new method of feeding.
It was important to find the missing puzzle, because now it is easier to trace the connection between holes and galaxies. As a result, we will be able to understand the type, quantity and principle of passage through a period of nuclear activity. And “jellyfish” are able to answer these questions.
