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.
