‘Dramatic’ black-holes, above all, scholars as a ‘weak’ galaxies, which quickly turn into ‘ravenous’ quasars

Scientists have obtained the first images of a black hole, with the Event Horizon Telescope observations of the center of the galaxy M87.

Astronomers have spotted a “dramatic” black holes and dark matter in six nearby galaxies, which could shed a new light on the galactic evolution.

“We have found that there is a whole new class of active galactic nucleus in a wimpy galaxy, a bright quasar,” said Suvi Gezari, an associate professor of astronomy at the University of Maryland, who led the research, in a statement. “The theory suggests that a quasar will need to take thousands and thousands of years, but our observations suggest that it could happen very quickly.”

A quasar is an active supermassive black hole.

Six of these galaxies are known as low-ionization nuclear emission-line region (LINER) galaxies. The astronomers were surprised to find out that the “kind-hearted” galaxies, there is a sudden change in the “ravenous” quasars.

“Our findings confirm that the LINERs may, in fact, that the host is active, supermassive black holes at their centres,” said Sarah Frederick, a graduate student at the University of Maryland, Department of Astronomy, and the research paper’s lead author, in a statement. “However, each of these six transitions were so sudden and tragic, it tells us that there is something else going on in these galaxies. We would like to know how to make such huge amounts of gas and dust, it can suddenly start to fall into a black hole.”

The astronomers used data from the Zwicky Transient Facility, a sky survey is a project from Caltech, the Palomar Observatory, near San Diego, for the research. The study, which was published in the Astrophysical Journal.

“One of the six objects, we first thought we had perceived as a tidal disruption event, that’s what happens when a star comes too close to a supermassive black hole, and it got torn up,” Frederick said in a statement. “However, we later found it was a previously dormant black hole, it undergoes a transition in which the astronomers call it a ‘changing look’, resulting in the bright quasar. The observations of six transitions, and all in a relatively quiet and LINER galaxies, and it suggests that we have identified an entirely new class of active galactic nucleus.”

Scientists are gaining a range of new insights into black holes and dark matter. In a separate project, and the experts it has recently been announced that a black hole swallowing a neutron star, has likely been detected for the first time.

In another project, researchers released the first-ever image of a black hole, earlier in the year, with the onset of the far-off object down to the smallest detail.
