They studied the X-ray spectra — that is the amount of X-rays seen at different energies — of sources within about 12 light years of Sgr A*.The team then selected sources with X-ray spectra similar to those of known X-ray binaries, which have relatively large amounts of low energy X-rays. This discovery could also inform future gravitational wave research.

Scientists will try to directly image Sagittarius A*, the black hole at the center of the Milky Way. This image from NASA's Chandra X-ray Observatory shows the center of our Galaxy, with a supermassive black hole known as Sagittarius A* (Sgr A* for short) in the center.

A study was done with the measured parallaxes and motions of 10 massive regions in the Sagittarius spiral arm of the Milky Way where stars are formed.

Baganoff et al. Other sources with relatively large amounts of high energy X-rays are labeled in white, and are mostly binaries containing white dwarf stars.Hailey and his collaborators concluded that a majority of these dozen X-ray binaries are likely to contain black holes.

Using intermittent observations over several years, Chandra has detected X-ray flares about once a day from Sgr A*. This appearance and nickname are misleading, though: the three-dimensional structure of the Minispiral is The Western Arc (outside the field of view of the image shown in the right) is interpreted as the ionized inner surface of the CND. I do not think so.

This recent analysis using Chandra data is the first observational evidence for such a black hole bounty.A black hole by itself is invisible.

The amount of variability they have shown over timescales of years is different from that expected for X-ray binaries containing neutron stars.Only the brightest X-ray binaries containing black holes are likely to be detectable at the distance of Sgr A*. Sagittarius A*, ook wel bekend als Sgr A*, is een superzwaar zwart gat en een radiobron in het centrum van de Melkweg.Het object bevindt zich in de samengestelde radiobron Sagittarius A op 25.900 lichtjaar van de Zon.Het bevat meer dan 4 miljoen zonsmassa's in een gebied met een radius van minder dan 6,25 lichtuur.

The Eastern Arm and the Bar seem to be two additional large clouds similar to the Northern Arm, although they do not share the same orbital plane. 02.08.12 . National Geographic.

Astronomers have discovered evidence for thousands of black holes located near the center of our Milky Way galaxy using data from Theoretical studies of the dynamics of stars in galaxies have indicated that a large population of stellar mass black holes — as many as 20,000 — could drift inward over the eons and collect around Sgr A*.

Using this method they detected fourteen X-ray binaries within about three light years of Sgr A*. Hailey et al.

Sagittarius A or Sgr A is a complex radio source at the center of the Milky Way which contains a supermassive black hole.It is located in the constellation Sagittarius, and is hidden from view at optical wavelengths by large clouds of cosmic dust in the spiral arms of the Milky Way..
