The continuing formation of early-type galaxies: an HI survey

A deep H I survey of nearby early-type galaxies carried out with the Westerbork Radio Synthesis telescope has shown that, contrary to expectation, neutral hydrogen is a significant constituent of the ISM in this type of objects located in low density environment. The studied galaxies are part of a r...

Description
Summary:A deep H I survey of nearby early-type galaxies carried out with the Westerbork Radio Synthesis telescope has shown that, contrary to expectation, neutral hydrogen is a significant constituent of the ISM in this type of objects located in low density environment. The studied galaxies are part of a representative sample of nearby E and SO for which integral-field spectroscopy using the SAURON spectrograph is available. We present preliminary results on the comparison of the characteristics of the H I with those of the molecular and ionised gas as well as the stellar dynamics and population.
