Astronomers Detect Mini-Supermassive Black Hole
Utilizing NASA’s Chandra X-ray Observatory, researchers have discovered a Mini-Supermassive Black Hole that is more than 200,000 times the mass of the Sun within Mrk 462 which is a dwarf galaxy with only a few hundred of million stars. Comparatively, our Milky Way has a few hundred billion stars. This Mini-Supermassive Black Hole is contained in dust and gas inside the Mrk 462 universe, which lies 110 million light-years away within the constellation referred to as Canes Venatici.
NASA announced in a blog post it’s the first instance it’s been reported that the “obscured” supermassive black hole is discovered in an elusive dwarf galaxy. Astronomers typically discover black holes by searching at the speed of motion of stars in the center of galaxies. However, dwarf galaxies are too tiny and dim for the majority of modern instruments to detect them .A different method used by astronomers to identify dark holes is to look for evidence of gas that has been heated hundreds of millions of degrees, and then glowing in light X-rays while it moves toward a black hole.
Jack Parker of Dartmouth College in Nh, who brought the research with friend Ryan Hickox, also from Dartmouth, stated the Mini-Supermassive Black Hole in Mrk 462 was one of the tiniest available.
Hickox stated that because hidden black holes are harder to spot as compared to those that were exposed, the discovery could signal the existence of many dwarf galaxies that have similarMini-Supermassive Black Hole.The researcher also said that this discovery could aid astronomers in determining the question of how black holes got this massive so early in the universe.
The scientists in this study employed Chandra to study eight dwarf galaxies that had previously offered indications of the growth of black holes and Of the three of them, only Mrk 462 could show the X-ray signatures of an expanding black hole.
What is the smallest supermassive black hole?
The smallest supermassive black hole ever identified is gobbling material at rates similar to its larger cousins, providing insights into how these behemoths evolve. Located at the heart of a dwarf galaxy known as RGG 118, the black hole contains about 50,000 times more mass than the sun.
Is a supermassive black hole rare?
Observational evidence indicates that almost every large galaxy has a supermassive black hole at the galaxy’s center. The Milky Way has a supermassive black hole in its Galactic Center, which corresponds to the location of Sagittarius A*.
What is the closest supermassive black hole to Earth?
Astronomers have found a pair of supermassive black holes that are closer to the Earth than any previously discovered. The duo are 89 million light-years from our planet in the constellation of Aquarius, more than 380 light-years closer than our next closest black hole pair.
