Gas accretion in galactic disks
Thijs van der Hulst, Renzo Sancisi
Evidence for the accretion of material in spiral galaxies has grown over the past years and clear signatures can be found in HI observations of galaxies. We describe here new detai…
The extra-planar neutral gas in the edge-on spiral galaxy NGC 891
Filippo Fraternali, Tom Oosterloo, Renzo Sancisi +1
We present neutral hydrogen observations of the nearby edge-on spiral galaxy NGC891 which show extended extra-planar emission up to distances of 15 kpc from the plane. 3D modeling…
Evidence for gas accretion in galactic disks
Thijs van der Hulst, Renzo Sancisi
Studies of the HI in galaxies have clearly shown that subtle details of the HI distribution and kinematics often harbour key information for understanding the structure and evoluti…
The mass distribution in early type disk galaxies
E. Noordermeer, J. M. van der Hulst, R. Sancisi +2
We are studying the mass distribution in a sample of 50 early type spiral galaxies, with morphological type betweens S0 and Sab and absolute magnitudes M_B between -18 and -22; the…
Holes and high velocity HI in NGC 6946
Rense Boomsma, Tom Oosterloo, Thijs van der Hulst +2
We are studying the properties of the holes and the high velocity gas in NGC 6946. Here we present some puzzling results.
High Velocity Gas in the Halos of Spiral Galaxies
Filippo Fraternali, Tom Oosterloo, Rense Boomsma +2
Recent, high sensitivity, HI observations of nearby spiral galaxies show that their thin `cold' disks are surrounded by thick layers (halos) of neutral gas with anomalous kinematic…
