21. ASP: Beacons in the Gloom
... In one situation, we can use light from quasars to probe the material between us and them because that light may pass through one or more galaxies or gas clouds on its way to us. The gas inside the galaxies or the intergalactic clouds acts then as a filter, absorbing selected wavelengths from the quasar light. ... Light from a quasar must pass through clouds of gas and even faint galaxies -- each leaving its imprint on the light -- before we receive it here on Earth. ... Gravitational lensing . ...

24. (S-7a) The Black Hole at the Center of our Galaxy
... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

26. Galaxy Evolution: Micr Quasars
... Galaxy Evolution home . ... Micro quasars Publications . ... In the last few years a very similar phenomenon has been observed in some X-ray binaries, binary stellar systems with one gravitationally-compact object (black hole or neutron star) and an "normal" star part of whos atmosphere is captured by the compact object. ... The compact objects (a few solar masses) are much smaller than those inferred in AGN (10 9 solar masses), and the sizes much smaller, so the analogy may not be complete. ...
