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…
Kinematics of the Ionised Gas in the Spiral Galaxy NGC 2403
Filippo Fraternali, Tom Oosterloo, Renzo Sancisi
We present a study of the kinematics of the ionised gas in the nearby spiral galaxy NGC 2403 using deep long-slit spectra obtained with the 4.2-m William Herschel Telescope. The da…
