The JCMT Nearby Galaxies Legacy Survey I. Star Forming Molecular Gas in Virgo Cluster Spiral Galaxies

C. D. Wilson, B. E. Warren, F. P. Israel +20

We present large-area maps of the CO J=3-2 emission obtained at the James Clerk Maxwell Telescope for four spiral galaxies in the Virgo Cluster. We combine these data with publishe…

The Globular Cluster Systems in the Coma Ellipticals. IV: WFPC2 Photometry for Five Giant Ellipticals

W. E. Harris, J. J. Kavelaars, D. A. Hanes +2

We analyze photometric data in V and I for the globular cluster (GC) systems in five of the giant ellipticals in the Coma Cluster: NGC 4874, 4881, 4889, 4926, and IC 4051. We find…

Bulge-Disk Decompositions and Structural Bimodality of Ursa Major Cluster Spiral Galaxies

Michael McDonald, Stephane Courteau, R. Brent Tully

We present bulge and disk (B/D) decompositions of existing K'-band surface brightness profiles for 65 Ursa Major cluster spiral galaxies. This improves upon the disk-only fits of T…

LCDM Satellites and HI Companions - The Arecibo ALFA Survey of NGC 2903

J. A. Irwin, G. L. Hoffman, K. Spekkens +11

We have conducted a deep, complete HI survey, using Arecibo/ALFA, of a field centered on the nearby, isolated galaxy, NGC 2903, which is similar to the Milky Way in its properties.…
