Elliptical galaxies outside dense clusters are observed to contain small amounts (relative to spiral galaxies) of cold interstellar gas. This
Blue Compact Dwarf and Dwarf Irregular galaxies are generally believed to be unevolved objects, due to their blue colors, compact
An imaging survey of CO(1-0), HCN(1-0), and HCO$^+$(1-0) lines in the centers of nearby Seyfert galaxies has been conducted using
The prominent interacting galaxy pair NGC 4038/9 contains many active star-forming regions and is continuously forming new star clusters. We
We first present a summary of our numerical work on accretion discs in close binary systems. Our recent studies on
We present high dispersion HST GHRS UV spectroscopic observations of 8 HII galaxies covering a wide range of metallicities and
We present new multi-wavelength data for the NGC 4410 galaxy group. This group contains the peculiar radio galaxy NGC 4410A,
Using a sample of 7 barred spirals from the BIMA Survey of Nearby Galaxies (SONG), we compare the molecular gas
We present new J=1-0 12-CO observations along the northern spiral arm of the grand-design spiral galaxy M100 (NGC 4321), and
We review recent observations of molecular gas in nearby galaxies and their implications for the star formation law on large
We present observations of OY Car, obtained with the Anglo-Australian telescope, during a normal outburst in 1991. Two sinusoidal components
In this contribution we present a few selected examples of how the latest generation of space-based instrumentation -- NASA's Chandra
Understanding the star formation process is central to much of modern astrophysics. For several decades it has been thought that
A brief review concludes that there is now good overall agreement between theoretical estimates of the energy associated with the
We have obtained CO(1-0) observations for a sample of 37 interacting galaxy systems, chosen from a parent sample of optically-selected
The preliminary results from a deep emission-line search for warm ionized material in the halos of nearby active and star-forming
