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 line-of-sight warp of the spiral galaxy ESO 123-G23
G. Gentile, F. Fraternali, U. Klein +1
We present 3-D modelling of the distribution and kinematics of the neutral hydrogen in the spiral galaxy ESO 123-G23. The optical appearance of this galaxy is an almost perfectly e…
