A database can be accessed on the web at http://edd.ifa.hawaii.edu that was developed to promote access to information related to galaxy distances. The database has three functional components. First, tables from many literature sources have been gathered and enhanced with links through a distinct galaxy naming convention. Second, comparisons of results both at the levels of parameters and of t...

Two interacting galaxies and four central galaxies in cooling flow clusters were observed with the Hubble Space Telescope to look for young compact massive star clusters. The two interacting galaxies, NGC 3597 and NGC 6052, show clear evidence for resolved bright blue clusters that are likely to be comparable in mass to Galactic globulars based on their colors and brightnesses. In NGC 3597, the...

We confirm the first detection of the molecular ion H+3 in an extragalactic object, the highly obscured ultraluminous galaxy IRAS 08572+3915 NW. We also have detected absorption lines of the fundamental band of CO in this galaxy. The CO absorption consists of a cold component close to the systemic velocity and warm, highly blueshifted and redshifted components. The warm blueshifted component is...

Using an absorption line from the metastable (J , K) = (3, 3) level of H3 together with other lines of H3 and CO observed along several sightlines, we have discovered a vast amount of high temperature (T ∼ 250 K) and low density (n ∼ 100 cm) gas with a large velocity dispersion in the Central Molecular Zone (CMZ) of the Galaxy, i.e., within 200 pc of the center. Approximately threefourths of th...

We have been investigating ways to restore images of objects obtained with a telescope under anisoplanatic atmospheric conditions. Anisoplanatic means that the point spread function due to atmospheric turbulence is position dependent. We began by looking at extended astronomical objects, such as craters on the moon but have turned our attention to extended objects on the earth’s surface imaged ...

This paper outlines a new applicaton of the technique of drift scanning, for single-dish radio continuum measurements within a radome. A radome scatters varying amounts of ground radiation into the receiver feed for di erent antenna positions, causing di cult-to-cancel total power uctuations as astronomical sources are tracked. Parking the telescope and allowing a source to drift through the be...
