The first black hole with intermediate-mass!
Scientists have discovered an intermediate-mass black hole, a missing link that connects black holes with a mass similar to that of the stars and the supermassive that can weigh the equivalent of millions or even billions of stars. This black hole discovered weighs the equivalent of 2,200 stars.
The intermediate-mass black hole has been observed in central star cluster called 47 Tucanae.
The leader of this study, Bulent Kiziltan of the Harvard-Smithsonian Center for Astrophysics (CfA) said:
We want to find intermediate-mass black holes because they are the missing link between stellar-mass and supermassive black holes. They may be the primordial seeds that grew into the monsters we see in the centers of galaxies today.
The 47 Tucanae is 12 billion years old cluster star, located 13,000 light years from Earth. It consists of thousands of stars, and the diameter of the agglomeration is only 120 light years. It also contains 24 pulsars that were essential to the investigation.
The 47 Tucanae has been examined in the past to see if the center of the cluster is a black hole. In most cases, a black hole is discovered by observing X rays coming from material orbiting the hole. This method only works if the black hole consumes the gas nearby. But in this case, the gas is missing in central star cluster. Also, the vast agglomeration center made observing the movements of the stars to be very difficult.
The new study is based on two sets of evidence. The first is the general movement of stars in 47 Tucanae. In an environment so dense, more massive celestial bodies tend to move toward the center of the swarm. This can be an indicator for the presence of a black hole in the middle of stars. Through computer simulations, the team could see after speeds and trajectories of stars, the nature of gravitational forces.
The second set of evidence comes from the pulsar; compact remnants of stars whose radiation can be easily detectable. Also, these objects swarming around the black hole. Being away from the center, indicates the presence of the stellar cluster in the middle. Combined, this evidence suggests the existence of a black hole with a mass of 2,200 stars.
The biggest black holes ever discovered
Scientists at the University of California, Berkeley, announced they had discovered two colossal black holes, located at a distance of 300 million light-years away from Earth, relatively close to the scale of cosmic distances.
A black hole is formed by the collapse of giant stars; is a region where gravity, which reaches enormous attract and retain everything with such force, that even light can not escape.
Experts say that the two newly discovered holes are the largest ever observed, each one 10 billion times larger than our sun. The previous "record" size, belonged to a black hole that was "only" 6 billion times larger than the sun.
The discovery suggests that there are differences in the way that black holes grow, depending on the size of the galaxy in which they find themselves.

It's very interesting post!!
Exchellent job again thank you for sharing :)
Glad you like it @djsonic! Thanks a lot!
Just to add a few pieces of information: the uncertainty on the intermediate black hole mass is still large. It lies actually between 700 and 3700 solar masses (and not the mass of any star, as could be guess from your post :p).
You may also want to add to our source this one that is the official scientific publication :D
Thanks for writing on this btw!
Thank you very much for the correction and for the comment. I don't really have time to add to your source and I don't know what to add. Feel free to add what do you want, is not a problem.
Or should I add your source to my post? Let me know. Thanks again @lemouth.
You can simply add a "source4" at the end of your post. Would be enough I guess :)
Done! I have added at the end of the post!
