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…
High velocity HI in NGC 6946 and extra-planar gas in NGC 253
Rense Boomsma, Tom Oosterloo, Filippo Fraternali +2
Multi-wavelength observations of nearby spiral galaxies have shown that neutral and ionized gas are present up to a few kpc from the disk and that star formation and supernovae pro…
Stationary fluid models for the extra-planar gas in spiral galaxies
M. Barnabe', L. Ciotti, F. Fraternali +1
We show how to construct families of stationary hydrodynamical configurations that reproduce the observed vertical gradient of the rotation velocity of the extra-planar gas in spir…
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…
The vertical structure and kinematics of HI in spiral galaxies
Renzo Sancisi, Filippo Fraternali, Tom Oosterloo +1
We discuss the distribution and kinematics of neutral hydrogen in the halos of spiral galaxies. We focus in particular on new results obtained for the nearby Sc galaxy NGC 2403 whi…
