Small Galaxy With A Big, Dark Heart

Supermassive black holes, which weigh millions to billions of times the mass of our Sun, are thought to reside at the heart of most—if not all—galaxies in the Universe. Such animals are characterized by their very heavy mass, their insatiable hunger and their messy table manners. These monsters are mysterious and confusing. But, the mystery became even more disturbing when a monster – moving in the incredible. 17 billion Suns— caught living in the heart of a strange little galaxy that’s almost entirely a black hole!

“That’s not what I was looking for. I expected to see supermassive black holes in supermassive galaxies,” Dr. Remco van den Bosch, astronomer in the Max Planck Institute in Heidelberg, Germany, on November 26, 2012 Science Now. Dr. Van den Bosch is the first author of a paper describing this amazing technology.

In 1915, Albert Einstein Theory of General Relativity prophesied the existence of an object with such a gravitational field that anyone who unfortunately gets too close to its opening mouth will vanish. However, the concept of really The existence of such monsters seemed so far-fetched that Einstein himself rejected the concept – but scientists now know that such animals can and Don’t there is.

A supermassive black hole forms when a supermassive star violently collapses in a bright firework of supernova explosion, signaling the end of its life as a progenitor (burning hydrogen). When a star hole is born, it can increase in size by feeding on its surroundings. Supermassive holes are believed to be born when a star’s mass increases by consuming stars and gas – as well as by merging with other black holes.

Astronomers have known for about a decade that perhaps every large galaxy in the universe has a vicious monster at its heart, kept in an evil secret. It could be a monster at least as big as our entire solar system. Named after the black hole of the Milky Way Galaxy Sagittarius A* (pronounced Sagittarius-a-star), and it is a calm old animal, except when it eats occasionally, and eats a large portion of the gas or star matter which unfortunately floats too close to its stomach. Sagittarius A* It weighs about 4 million times more than our sun.

It is believed that supermassive black holes are subject to normal relativity. That is, the heavier the star that shines in the center of the galaxy, the bigger the fierce beast that lives there. This means that the mass of a flaring galactic nugget is about a thousand times that of a galaxy.

However, the small galaxy, NGC 1277, seems to be marching to the beat of a different drum. The small galaxy, which is about 250 million light-years from our planet, has a giant monster at its heart that makes up 14% of its total mass. Most other galaxies are thought to obey the “standard relativity” beat, and have black holes that account for 0.1% of their total mass.

“This is a very strange galaxy. It is almost entirely a black hole. It may be the first object in a new class of black hole galaxy systems,” said Dr. Karl Gebbardt, a member of the research team, in a statement issued on November 28, 2012. Space.com. Gebbardt is at the University of Texas at Austin.

The study, published in the journal November 29, 2012 characterfound that if this supermassive black hole were at the center of our own solar system, it would swallow up all eight major planets and expand to about 10 times the size of the dwarf planet Pluto and the type of ice that collapses. the cold dark, far from Kuiper belt.

NGC 1277 is a small member of the group of galaxies found in the constellation of Perseus. It also represents a common type of galaxy that resides in clusters. This small galaxy with a large, dark heart is called lenticular galaxy, meaning a stunning cross between a twisted and oblong round galaxy. Spirals is a giant flaming chariot wheel, like the Milky Way, and populated by stars of all ages. Ellipticals they are in the form of giant balls, and the first are the red and old stars. Like an oblong round, NGC 1277 it no longer produces flaring stars, and is mainly hosted by old stars. The youngest star in the small galaxy is 8 billion years old – that is, they twice the age of our old Sun, which is about 4.56 billion years. However, like cute, wheel-shaped twisted, NGC 1277 disc sports that sparkle brightly with bright stars.

“Maybe this thing is a relic from the past,” said Dr. Van den Bosch continued the evaluation on November 28, 2012. Science Now. He went on to explain that the giant pit was burning with fire quasars–the most active galactic nuclei (AGN) ever to inhabit the early Universe — space froze shortly after the Big Bang. Perhaps, he suggested, NGC 1277 shows a phenomenon of arrested evolution, and began its galactic childhood as a supermassive black hole, but failed to trap a burning star. In other words, like Peter Pan, NGC 1277 “didn’t grow up”! Her galactic sister, roaring with her in the Perseus cluster, would have selfishly accepted the stars that allowed the little poor NGC 1277 to become a starry galactic adult.

Image of NGC 1277 The supermassive monster may be larger than the second runner known today, whose mass is calculated (although not confirmed) to be between 6 billion and 37 billion solar-masses. This beast lives in the dark heart of the galaxy Image of NGC 4486Band makes up about 11% of the neck of the central galaxy.

Said Dr. Van den Bosch on November 28, 2012 Space.com but his team found the supermassive black hole during their survey to hunt for “the biggest black holes we’ve ever seen.”

Astronomers carefully studied the light from 700 galaxies, using the Large Light-Gathering Telescope, the Hobby-Eberly Telescopeat the University of Texas at Austin McDonald Observatory. The team found that six of the galaxies tested had stars and other objects flying through them, at a maximum speed of 218 miles per second! The galaxy, like NGC 1277, they are also small — just 9,784 light-years, or less. The team suspected that black holes were responsible for these measurements, and used archival data NGC 1277 from the hon Hubble Space Telescope. That’s how they saw it Image of NGC 1277 big, dark heart.

Dr. Van den Bosch is interested in whether these supermassive black holes formed only in the early Universe, or whether they formed later in its history. Since then. It could be a relic of the star formation and galactic formation at that time,” he commented on November 28, 2012. Space.com.

The team is trying to figure out if NGC 1277 is one of a kind. However, according to astronomer Dr. Chung-Pei Ma of the University of California at Berkeley on November 28, 2012. Science Now: “When you have a really strange system, you can almost always cook up a theory. But if these galaxies form a class of their own, that’s really exciting.”
