... 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. ...

As the Universe expands, gravity pulls on the Universe, and slows the expansion down over time. As we look to great distances, we are looking back in time. If we can measure how fast the Universe is expanding in the past, and compare it to how fast it is expanding now, we can see the total gravitational effect of all matter in the Universe. Here we plot the distance between two galaxies as a function of time. ... Universes with lots of material . ...

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. ...

Search for the youngest galaxies and the problems of galaxy formation . During 2 last years of work on the search for new galaxies in the phase of first star formation (SF) burst there were carried out spectral observations of 39 blue compact galaxies (BCGs) - candidates to the most metal deficient unevolved galaxies. 23 of them indeed have appeared new metal-poor galaxies with the oxygen abundance (O/H) (as an indicator of chemical evolution) less than 1/10 of the solar value. ...
