Thermal electron conduction can be an effective heating agent and we examine w

The physical properties of the nebulae are presented, the difficulties posed by the nebulae for the standard cooling flow scenario are discussed, and possible sources for the origin and ionization of the gas are explored. The evidence points to

Finally, we look at the interplay between galaxy morphology and luminosity on one side, and the supercluster environment (local density) on the other. We discuss recent evidences showing that galaxi

By combining data from quasars and low-redshift radio galaxies, it is shown that they can both be consistently described by a single luminosity function and evolution law. Possible expl
