Warp or lag? The ionized and neutral hydrogen gas in the edge-on dwarf galaxy UGC 1281

Understand

The properties of gas in the halos of galaxies constrain global models of the interstellar medium.

• Kinematical information is of particular interest since it is a clue to the origin of the gas.
• Until now mostly massive galaxies have been investigated for their halo properties.
• Here we report on deep HI and H{\alpha} observations of the edge-on dwarf galaxy UGC 1281 in order to determine the existence of extra-planar gas and the kinematics of this galaxy.
