Time Delay of PKS1830-211 Using Molecular Absorption Lines
T. Wiklind, F. Combes
The use of molecular absorption lines in deriving the timde delay in PKS1830-211 is described, as well as results from a three year monitoring campaign. The time delay and the impl…
Formation of Gaseous Shells
F. Combes, V. Charmandaris
HI observations have revealed in several shell galaxies the presence of gaseous shells slightly displaced from the stellar shells radially, in the outward direction. We propose a m…
Bar-driven Galaxy Evolution and Time-scales to Feed AGN
F. Combes
Recent progress in the understanding of the role of bars and gravitational instabilities in galaxy disks is reviewed. It has been proposed that bars can produce mass transfer towar…
HI Spatial Distribution in the Galaxy NGC 3783
J. A. Garcia-Barreto, F. Combes, B. Koribalski +1
We have mapped the emission from atomic hydrogen at 21 cm from the galaxy NGC 3783 with the Australia Telescope Compact Array. Our main results are: a) the HI morphology is irregul…
Spiral Galaxies and Tracers of Mass Accretion
F. Combes
Can the present dynamics of spiral galaxies tell us something about the merging history, the formation and evolution of disks? Galaxy interactions thicken or destroy disks; the sim…
Bulge Formation
F. Combes
The currently discussed theories of bulge formation are reviewed, including the primordial scenario, where bulges form rapidly and then accrete disks, the secular scenario, where b…
