Ram-pressure feeding of supermassive black holes
The majority of ‘jellyfish’ galaxies, characterized by long ‘tentacles’ of gas, also have active nuclei, indicating that gas is being fed to the central supermassive black hole by ram pressure.

The Impact of Surveys
Since the most ancient times astronomers felt the need to collect and list in atlases and catalogs all the visible objects in the sky. The first stellar catalog known in the western world being the one of Hipp.....

The New Boundaries of the Galaxy Concept
“…Bertoldo demonstrated that even when he was tearing out marble to get rid of what he did not want he must work with rhythmical strokes so that he achieved circular lines around the block. He was never to com...

In Pursuit of High Redshift Galaxies
Some contributions in Chap. 1 have highlighted the impact of the discovery in the 1960s of a handful of radio galaxies and Quasars in the redshift range z ∼ 0.2–0.4. About 40 years later, at the end of t...

EMISSION LINE GALAXIES IN CLUSTERS
At the present epoch, clusters of galaxies are known to be a hostile environment for emission-line galaxies, which are more commonly found in low density regions outside of clusters. In contrast, going to high...

Optical Spectra of Dusty Starbursts
This contribution presents the optical spectral properties of FIR-luminous galaxies, whose distinctive feature is often the simultaneous presence in the spectra of a strong Hδ line in absorption and of emissio...
