For unknown reason, the
black hole (BH), located in the center of our Milky Way galaxy, regarding once
a day generates an X-ray flash. Such outbreaks last for several hours, and
their brightness can in some cases exceed the normal brightness of the black
hole, even a hundred times. But in February 2012, astronomers using the X-ray
Observatory "Chandra", recorded the most powerful flare ever observed
on the central black hole in our galaxy known as Sagittarius A *.
The
luminosity of the outbreak, which took place over 26 000 light-years from us,
was 150 times higher than the standard luminosity of the black hole in our
galaxy.
The authors of the new
study, Michael Novak and Frederick C. Baganoff of the Kavli Institute at the
Massachusetts Institute of Technology believe that one of the reasons for this
behavior could be a black hole approximation of it asteroid black hole ripped
apart and swallowed, which was accompanied by the emission of large amounts of
energy. Scientists also believe that in fact the flash Sagittarius A * may be
more frequent than previously thought, and they reserve time on the telescope
"Chandra" for additional observations.
Their work was
presented in the journal The Astrophysical Journal.
