2. RCJ0311+0507
... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...

3. Search for distant radio galaxies in SAO
... The search for distant objects which can be both galaxies and quasars is one of the most important problems of observational astrphysics, because it allows one to determine cosmological parameters connected with the time of appearence and evolution of stellar systems, large scale structure of the Universe. ... Radio galaxies are important objects to be studied because they are sources of infrared-optical-ultraviolet continuum, emission lines and continual radio emission. ...

5. 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 . ...

... 1.4 Completed WF/PC-2 8592 (Pixel Microlensing of M87) The WF/PC-2 was used to undertake a pixel microlensing study of M87 in order to: 1} probe the lower end of the M87 IMF via star-star lensing, 2} possibly obtain the first evidence of Massive Compact Objects (MACHOs) in the halo of a galaxy other than our own, and 3} search for intracluster MACHOs. ... They are also the only sample of galaxies selected on the basis of their mass rather than their luminosity or surface brightness. ...
