Theories of how galaxies, the fundamental constituents of large-scale structure, form and
evolve have undergone a dramatic paradigm shift in the last few decades. Earlier views …

Observations of the molecular gas in galaxies are vital to understand the evolution and star-
forming histories of galaxies. However, galaxies with molecular gas maps of their whole …

We present ground-based measurements of 126 nearby galaxy centers in 12 CO and 92 in
13 CO in various low-J transitions. More than 60 galaxies were measured in at least four …

HI 21 centimeter observations and I-band CCD surface photometry of spiral galax ADS Classic
is now deprecated. It will be completely retired in October 2019. This page will automatically …

We have used the VLA to image the neutral hydrogen emission from the Seyfert galaxy GC
3227, with angular resolutions ranging from 12 to 60 arcsec. We detect plumes of H i …

Particle hydrodynamics (SPH) simulations are presented of direct collisions between two
model galaxies, most consisting of a rigid halo and a gas disk. Local self-gravity is also …

By combining test-particle and self-consistent techniques, we have developed a method to
rapidly explore the parameter space of galactic encounters. Our method, implemented in an …

We have used the Galaxy Evolution Explorer (GALEX) ultraviolet telescope to study stellar
populations and star formation morphology in a well-defined sample of 42 nearby optically …

We present high spatial resolution X-ray imaging data for the interacting galaxy pair NGC
7714/7715 (Arp 284) from the Chandra X-ray telescope. In addition to the unresolved …

We have used the VLA B and C Arrays to make 21 cm HI observations of the peculiar galaxy
NGC 2782 (Arp 215). These observations are complementary to previously published D …
