HI Imaging Observations of Superthin Galaxies. II. IC2233 and the Blue Compact Dwarf NGC2537
Lynn D. Matthews, Juan M. Uson
We have used the VLA to image the HI 21-cm line emission in the edge-on Sd galaxy IC2233 and the blue compact dwarf NGC2537. We also present new optical B,R, and H alpha imaging of…
VLA Observations of HI in the Circumstellar Envelopes of Asymptotic Giant Branch Stars
Lynn D. Matthews, Mark J. Reid
(Abridged) We have used the VLA to search for neutral atomic hydrogen in the circumstellar envelopes of five AGB stars. We have detected HI 21-cm emission coincident in both positi…
VLA Observations of HI in the Circumstellar Envelopes of AGB Stars
Lynn D. Matthews, Mark J. Reid
We present the results of a VLA search for HI emission in the circumstellar envelopes of five nearby AGB stars: RS Cnc, IRC+10216, EP Aqr, R Cas, and R Aqr. We have detected emissi…
Clues on the Structure and Composition of Galactic Disks from Studies of "Superthin" Spirals: the Case of UGC3697
Lynn D. Matthews, Juan M. Uson
We summarize results from an HI+optical imaging study of the ``Integral Sign'' galaxy, UGC3697. UGC3697 is a low-mass, Sd spiral that exhibits a ``superthin'' disk morphology despi…
Starbursts and the Evolution of Gas-Rich Galaxies
John S. Gallagher, Christopher J. Conselice, Lynn D. Matthews +1
Moderately luminous starbursts in the nearby universe often occur in disk galaxies that are at most subject to mild external perturbations. An investigation of this type of galaxy…
Properties of `Superthin' Galaxies
L. D. Matthews, W. van Driel, J. S. Gallagher
`Superthins' are a subset of edge-on spiral galaxies exhibiting disks with large axial ratios (a/b>10), extraordinarily small stellar scale heights, and no bulge component. These a…
