Decode the black hole secret in the Milky Way 2 million years ago

Astronomers have found the solution to the birth of "black hole giants" in the universe.

>>>The galaxy's giant black hole "rejects food"

For years astronomers have not yet explained why our Milky Way lies in the middle of a supermassive Black Hole (SMBH) forest. But today, it seems astronomers have solved the mystery of the birth of the "giants" of this galaxy in the early history of the universe.

It is the collision and combination of primordial galaxies , their black holes merged, gradually becoming a super-massive black hole , heavier than the Sun at least 4 million times.

"If we could go back 2 million years and observe them, maybe the situation would be very different - the Milky Way's black hole could be," said study co-author Philip Maloney of the University of Colorado in Boulder. 10 million times brighter, I suppose, anyone hopes that, SMBH can change the brightness on a large scale in such a short time ".

Astronomers had previously suspected an explosion of "hibernating" black holes, but now, they believe, I have found a "fossil imprint" of my last meal "monster." the other "universe .

The research team suspects that a brilliant gas out of the galaxy may be the fossil of the SMBH eruption two million years ago.

The team studied gas strips that wrap around the Milky Way or Magellan flow . From that point on, it is the energy that erupted from SMBH 2 million years ago that caused the flow of hydrogen gas in the flow of Magellan to light up and be ionized , just like the ultraviolet light we see on Earth. This ionization of the Magellan lineage led scientists to discover it two decades ago.

Recently, scientists have just learned evidence of the past eruption of two giant bubbles spewing gamma beams in the center of the Milky Way.

Accordingly, infrared and X-rays saw more small clouds around the Milky Way. Astronomers now believe that many clouds of gas around SMBH can be activated, creating an explosion in the future. However, it will not pose a threat to the Earth.

The study is published in the Astrophysical Journal.
