The news about gravitational waves are still hot. And amid all this scientific discovery echoes still time to new findings and discoveries. Some amazing discoveries that reveal secrets about one of the most important discoveries in the history of physics. For example, how black holes appear twins? If you remember, these two holes are responsible for gravitational waves detected by LIGO . A strange, exotic and wonderful system that has opened the doors to new advances in physics. And now understand a little better how it might appear.
The sigh of a star
A huge parent star would have generated two black holes dying. The gamma ray signal could be understood as the last “sigh” Star
Now we explain how to observe a black hole. An object that by definition can not expect to “see” in any way. However, during last September Fermi Space Telescope detected gamma-ray burst from a star a split second before LIGO find the signal of gravitational waves. Now, a study led by the Center for Astrophysics Harvard-Smithsonian shows that this outbreak could belong to the star that led the pair of black holes twins. As explained from the center, the progenitor star would have generated the two holes at death. The gamma ray signal could be understood as the last “breath” of the star.
How these black holes were generated twins?
According to experts, when a star dies as we speak, huge and very massive (with a lot of mass) can I collapse due to gravity, increasing its mass to incredible levels, creating a black hole. In the case of black holes star twins probably turned so fast that I think two bodies apart . These masses in turn collapsed as he would have the star itself, creating two black holes between 29 and 36 times the mass of our sun.
His training would begin with two smaller stars, which is another outcome that may result as the progenitor star: creating two stars ‘children’ orbiting with respect the other turning. In the end, mass was such that the star “envelope” collapsed inward , eventually forming two black holes rotating relative to each other, like two “black stars” are treated. This special structure has been crucial to find and characterize gravitational waves.
A “gravity”
signal for the “odd” couple constituted with the features we have observed, twins born black holes had very close to each other, wrapped in the remnants of the star. Researchers predict that the distance between itself should not be greater than, for example, the size of the Earth and appearing within minutes. In the process of absorbing all this star stuff, huge jets relativists generate large mass jets traveling at nearly the speed of light. These are responsible for the “breath” of the star talked. Hence the gamma ray burst detected by the Fermi space telescope arises.
The signal of these gamma rays came 0.4 seconds before the signal of gravitational waves detected by LIGO. Unfortunately, the source was not confirmed by the European gamma-ray telescope INTEGRAL. Normally any detection is contrasted with other results to secure data. In this case, the detection of gamma rays represents more facilities to detect objects like black holes twins watching a new spectrum of information. As the center’s researchers say, although the signal of gamma rays detected by Fermi was false, that does not mean there is no need to keep looking gamma objects rays that can emit susceptible gravitational waves being studied.

Now, yes it would mean that this hypothetical origin of black holes twins should be reviewed . If, however, this signal of gamma rays (or other other similar objects) confirmed will have a new tool that will help us in the hunt for new events and “gravitational” signs , ie, new outbreaks where to find data on the novel (and still mysterious) gravitational waves. As we say, this finding was probably one of the most important in the history of physics. Who knows what doors have opened to discover this pair of black holes twins.
