Extragalactic Astronomy
Low Surface Brightness Galaxies
I have several very productive collaborations with Lynn Matthews to
study the dust content, observed disk color gradients, and the shape of
rotation curves in LSBs. A detailed study of the galaxy UGC 7321 is
presented in
Matthews & Wood (2002). More recently in
Matthews & Wood (2003), we have studied the high
latitude neutral hydrogen in UGC 7321, and have modeled this emission
with a warped and flared disk plus an extended H I halo in which the
rotational velocity declines with height above the galactic midplane.
