... 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. ...

... 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"). ...

Our understanding of star formation in galaxies is facilitated by observations, at multiple wavelengths, of emission which traces stellar populations. ... Using optical integral field spectroscopy, my work aims to better understand the local SFR calibrations, which use H-alpha and radio continuum emission, when applied to different regions of a galaxy, as well as to galaxies as a whole. ...

K-band Arcetri Obscured Supernova Search . What is the KAOSS Project? W hat is the KAOSS Project? Some recent surveys aimed at detecting Supernovae (SNe) in the optical have found that starburst galaxies do not show evidence for an enhanced SN rate, with respect to quiescent galaxies (Richmond et al. ... A similar result was obtained by Navasardyan et al. (2001) who looked for SNe in interacting galaxies, finding no evidence for correlations between SN rate and galaxy properties. ...

. In this comparison of actual observations with simulations, the top images show Hubble observations of the density of gas in the central portion of two galaxies. The bottom images are computer simulations that are remarkably similar to the Hubble observations. Knots of star formation in the two galaxies show how gas falling into a galaxy's center is controlled by jets from the central black hole. NASA/ESA/M. Donahue (Michigan State Univ.)/Y.

... It is reasonable to expect a priori that the evolution of events is strongly time dependent, so the star formation history in a galaxy is another important parameter. Therefore, by calculating the evolution of events after a -function like star formation burst,   one gets a Green function for any arbitrary star formation history. ... The source evolution in a galaxy with given star formation rate is thus calculated as . ...
