Galaxy Interactions, accretion, minor mergers
R. Sancisi, F. Fraternali (Univ. of Bologna), T. Oosterloo (ASTRON, Dwingeloo)
and T. van der Hulst (Univ. of Groningen) have continued
their study of cold gas accretion in galaxies and have written a review
published in Astron Astrophys Rev (2008) 15:189-223.
They have concluded that there is a mean ``visible" accretion rate of cold gas
in galaxies of at least 0.2 M/yr.
High velocity gas and HI halos of spiral galaxies
R. Boomsma (Univ. of Groningen), T. Oosterloo (ASTRON, Dwingeloo), F. Fraternali (Univ. of Bologna), T. van der Hulst (Univ. of Groningen) and R. Sancisi have completed the study of the vertical structure and kinematics (high-velocity gas and HI holes) of the HI in the spiral galaxy NGC 6946. The results have been presented in a paper (A&A in press, 2008, arXiv/0807.3339B).
