Astronomers from MIT, in the US, think that they have discovered a clear proof that black holes emit powerful streams of energy when they swallow stars. The MIT researcher Dheeraj Pasham conducted this study with his counterparts from the Johns Hopkins University (JHU) and published the report of the study, yesterday.
The researchers analyzed the data about a supermassive black hole
According to Pasham, the astronomers from MIT and JHU analyzed the radiations emitted by a supermassive black hole when it was swallowing a star.
Besides all, this is very rare observation and astronomers were happy they could’ve recorded it 4 years ago when they used a worldwide telescopes network to capture the emissions of a black hole located at more than 300 million light-years away from the Earth while it was swallowing a star.
Before the recent examinations, scientists believed that X-rays were expelled from the black holes when they absorb stars.
However, during the recent study of that event, the MIT scientists were able to observe something that has gone unnoticed before. Namely, about two weeks after the black hole swallowed the star, powerful streams of energy were released from the black hole following the X-rays emissions.
Black holes emit powerful energy streams when they swallow stars
Pasham considered that these streams following the X-rays emission are particularly caused by the black holes when they absorb stars. In essence, it could be said that the black holes are ingesting the stars.
These energy emissions, according to the recent study, may regulate a galaxy’s development because these streams are containing very powerful energies levels.
“Jets can halt star formation in galaxies if they’re strong enough but not all black holes produce strong enough jets. That’s something we don’t understand,” explained Pasham.
In conclusion, Pasham and his colleagues consider that they have shown that black holes emit powerful streams of energy when they swallow stars. However, the scientists hope to comprehend more these events, eventually.
