HI clouds in the proximity of M33
M. Grossi, C. Giovanardi, E. Corbelli +5
Neutral hydrogen clouds are found in the Milky Way and Andromeda halo both as large complexes and smaller isolated clouds. Here we present a search for Hi clouds in the halo of M33…
The HI distribution in the outskirts of M33 with the ALFALFA survey
M. Grossi, C. Giovanardi, E. Corbelli
Spiral galaxies appear to be dynamical systems whose disks are still forming at the current epoch and which continue to accrete mass. The presence of extraplanar gas in spirals ind…
Early-type galaxies with neutral hydrogen in the Virgo cluster from the ALFALFA survey
S. di Serego Alighieri, M. Grossi, C. Giovanardi +2
We extend our published work on the neutral hydrogen content of early-type galaxies in the Virgo cluster using the catalogue of detected sources from the ALFALFA survey, by showing…
