We present the Allen Telescope Array Twenty-centimeter Survey (ATATS), a multi-epoch (12 visits), 690 deg(2) radio image and catalog at 1.4 GHz. The survey is designed to detect rare, very bright transients as well as to verify the capabilities of th

We present multiple-field imaging simulations that explore the issue of large-scale flux recovery using five current and future millimeter-wavelength interferometers. The simulations show that nonlinear deconvolutions routinely applied to interferome

We present the first results of the BIMA Survey of Nearby Galaxies (BIMA SONG), an imaging survey of the CO J=(1-0) emission in 44 nearby spiral galaxies at a typical resolution of 6". BIMA SONG differs from previous high-resolution CO surveys in tha

We present BIMA observations of the HCN emission from five nearby spiral galaxies. The HCN observations comprise the first high-resolution (5--10\arcsec) survey of dense molecular gas from a sample of normal galaxies, rather than galaxies with prolif

The Pi GHz Sky Survey (PiGSS) is a key project of the Allen Telescope Array. PiGSS is a 3.1 GHz survey of radio continuum emission in the extragalactic sky with an emphasis on synoptic observations that measure the static and time-variable properties

We present observations of the HCN and HCO+ J=1-0 transitions in the center of the nearby spiral galaxy NGC 6946 made with the BIMA and CARMA interferometers. Using the BIMA SONG CO map, we investigate the change in the I_HCN/I_CO and I_ HCO/I_CO int

We discuss the latest results from the BIMA Survey of Nearby Galaxies (BIMA SONG), which was completed in the summer of 1999. By imaging the CO emission in the inner disks of 44 nearby spirals, we are creating a consistent database of information on
