subject: From our Galaxy Goes Black Hole [print this page] Haida used the resources of the digital sky survey (Sloan Digital Sky Survey), the database, using X-ray sources. While working on his project student saw that the black hole was visible as clearly as a star when viewed from the X-ray telescope "Chandra".
Black holes are believed to be in the center of most galaxies, and most of them weigh a billion times larger than our Sun. The reason for the motion of a massive black hole in the galaxy, which is half a billion light-years, may be a merger between two smaller black holes, under special conditions. This convergence of two black holes can create what scientists call a negative effect of black hole, which is a consequence of the increase of gravitational waves as a result of the merger.
However, the black hole, which is considered a set of bright X-rays, may also be a bright blue supernova, resulting from the collapse of a star, and the latest discovery does not reflect reality, as reported on the University website.
"We have found even more strange class of X-ray sources - said in a written statement, Hayden. - However, in order to more accurately determine the type of these objects, we need accurate data from the satellite by NASA's Chandra.
Over the past few years, researchers have discovered several similar cases - when the object, which is considered a black hole, came out of its galaxy, but then this would be a mistake to scientists.
In a statement university also said that the Laser Interferometric Space Antenna (LISA), which is being developed by request of NASA and the European Space Agency (ESA) and is scheduled for launch in the next 8-10 years will be able to more accurately measure the gravitational waves from the merger of two black holes. They want to use LISA to detect massive black holes at the centers of galaxies that formed out of two black holes of smaller size.
