... 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. ...

The Las Campanas Redshift Survey observed redshifts for more than 20,000 galaxies in the South and North galactic polar caps. Plotted above is a dot for each galaxy showing its right ascension (RA) and recession velocity (cz). The color of the dot shows which declination stripe (Dec) the galaxy is in. The dots for more distant galaxies are bigger to allow for the fact that only a small fraction of all galaxies are luminous enough to be seen at great distances. ... Tutorial: Part 1 | ...

Abstract -- Abundances of heavy elements decreases with increasing galactocentric distance almost in all disk galaxies. ... To explain this gradient in young objects and in the interstellar gas one has to assume that a typical disk galaxy is an open system, i.e. it expels some synthesized heavy elements into the circumgalactic space and/or accretes intergalactic gas with zero metallicity, with rates of both processes depending on the galactocentric distance. ...
