Moreover, this change in speed is directed toward a compact radio source
, called Sagittarius A*, that lies at the presumed location of the black hole.
In a separate study, researchers have for the first time directly detected infrared emissions from a compact radio source
, Sagittarius A*, which has been identified as a candidate for the black hole thought to lie at our galaxy's center.
Among specific topics are connections between jet parameters and black hole masses in quasars, where accretion disk around black holes end, the x-ray view of compact radio sources
, scientific highlights of the MAGIC collaboration observations of AGN, winds and outflows from supermassive black holes, and a dichotomy in radio jet orientation in elliptical galaxies.
The spectra were taken of previously identified compact radio sources
in the nearby spiral galaxy NGC 6946.
