... 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"). ...

... Oleg V. Verkhodanov . ... The last few years have changed our view on the evolution of galaxies: the most distant galaxies (i.e. systems having stellar population) have been found at redshift z=6.68 (Chen H.-W., Lanzetta, K. M., Pascarelle, S. 1999, Nature, 398 , 586) and radio galaxy at z=5.19 (van Breugel W., De Breuck C., Stanford S. A., Stern D., Rottgering H., Miley G. 1999. astro-ph/9904272 ). ...

... 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. ...

Color distribution in the inner part of the galaxy is very non-homogeneous and asymmetric. ... The map of distribution of $Q_{VRI}$ shows the presence of "blue" (in sence of low $Q_{VRI}$) nucleus and rather "red" inner disk with radius $R\sim 3 kpc$. ...

... 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. ...
