... 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"). ...

GALAXIES IN THE FIELD OF GRB 021004 I.V.Sokolov, Yu.V.Baryshev, T.A.Fatkhullin Results of the B,V,R,I investigations (counts, photometric red shifts, etc.) of the field of size ~ 4\'.3 x 4\'.3 centralized at the host galaxy of GRB 021004 are presented. ... The exposure times were: 3600s (B), 3600s (V), 2700s (R), 1800s (I). Photometric red shifts of these galaxies up to z ~ 3 were determined. Galaxies with a possible broad absorption at 2200A (in the rest frame) were selected. ...

... 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 . ...
