Black holes are creating havoc in unsuspecting places, according to a new study equipped with NASA’s Chandra X-Ray observatory. Astronomers have found the first pair of super-massive black holes in a spiral galaxy similar to the Milky Way. The most astonishing part for the astronomers is the discovery of first reaching explosives activity due to these giant black holes in these old galaxies.
After researching about them in detail, the astronomers have discovered that the super massive black holes are with masses ranging from millions to billions of times of the sun and are locating at the centre of the galaxy. They have the capacity to guzzle up a large amount of gas and dust that have been taking a shape of a disc around the mass which later falls into the black hole and a large number of particles streams out seeming as cloudy strips. When the matter falls towards these black holes, it glows with such brilliance and they can be seen billions of lights years away. Astronomers named these voracious black holes “quasars”.
After gathering data from 51 quasars which were perceived by Chandra, the group looked at the data more intently and observed that these quasars seemed to produce low carbons emissions at ultraviolet wavelength. This information led them to run assumptions which ceased that there are some quasars which are like hungry beasts that allure ample amount of gas and dust which make a structure like donut instead of the disc around the black hole.
The insatiable quasars acts as a protector to these donuts. They defence these donuts from snooping telescopic eyes. Thus it seems so vague to Chandra. “If a quasar is embedded in a thick donut shaped structure of gas and dust”, said team member Jinfeng Wun. “The donut will absorb much of the radiation produced closer to the black hole and prevent it from striking gas located further out, resulting in weaker ultraviolet atomic emission and x-ray emission”. There have been possibilities shown of the black hole growing at a much faster rate than others.
The good news it’s not devouring in the moment, at least not until the milky way diverges with Andromeda in around 4 billion years.
