  • Arecibo 21cm obs. of sources in 5 GMC regions

    We report Arecibo 21cm absorption-emission observations to characterize the physical properties of neutral hydrogen (HI) in the proximity of five giant molecular clouds (GMCs):...
  • GALFA-HI search for local dwarf galaxies

    In recent years, ultrafaint dwarf (UFD) galaxies have been found through systematic searches of large optical surveys. However, the existence of Leo T, a nearby gas-rich dwarf,...
  • Faint radio sources in GOODS-N and -S. I. VLA 5GHz

    We present the first results from the deep and wide 5GHz radio observations of the Great Observatories Origins Deep Survey (GOODS)-North ({sigma}=3.5{mu}Jy/beam, synthesized...
  • LMC and Cen A 1.3-10GHz polarization behavior

    We present a broadband polarization analysis of 36 discrete polarized radio sources over a very broad, densely sampled frequency band. Our sample was selected on the basis of...
  • The population of compact radio sources in ONC

    We present a deep centimeter-wavelength catalog of the Orion Nebula Cluster (ONC), based on a 30hr single-pointing observation with the Karl G. Jansky Very Large Array in its...
  • Parameters of radio sources near Sgr A*

    We present radio images within 30" of Sgr A based on recent VLA observations at 34 GHz with 7.8 {mu}Jy sensitivity and resolution of ~88x46 mas. We report 44 partially resolved...
  • Australia Telescope Low-brightness Survey (ATLBS)

    The Australia Telescope Low-brightness Survey (ATLBS) regions have been mosaic imaged at a radio frequency of 1.4GHz with 6" angular resolution and 72{mu}Jy/beam rms noise. The...
  • SEDs of type I AGN in COSMOS. I. XMM-COSMOS

    The "Cosmic Evolution Survey" (COSMOS) enables the study of the spectral energy distributions (SEDs) of active galactic nuclei (AGNs) because of the deep coverage and rich...
  • FIRST-2MASS dust-reddened QSO spectra

    We present a sample of 120 dust-reddened quasars identified by matching radio sources detected at 1.4GHz in the Faint Images of the Radio Sky at Twenty Centimeters survey...
  • Fermi/LAT AGN at 5GHz

    The parsec-scale radio properties of 232 active galactic nuclei, most of which are blazars, detected by the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space...
  • Spitzer survey of submillimeter galaxies

    We present Spitzer-IRAC and MIPS mid-IR observations of a sample of 76 radio-detected submillimeter-selected galaxies (SMGs) with spectroscopic redshifts, the largest such...
  • The FIRST-2MASS red QSO survey. II.

    We present results on a survey to find extremely dust-reddened Type 1 quasars. Combining the FIRST radio survey, the 2MASS Infrared Survey and the Sloan Digital Sky Survey, we...
  • Extragalactic point sources in WMAP 5-yr maps

    We present the results of an extragalactic point source search using the five-year Wilkinson Microwave Anisotropy Probe (WMAP) 41, 61, and 94GHz (Q, V, and W bands) temperature...
  • Arecibo methanol maser Galactic Plane Survey

    We present the results of an unbiased survey for 6.7GHz methanol masers in the Galactic plane carried out using the 305m Arecibo radio telescope. A total of 18.2deg^2^ was...
  • 90-GHz observations in NGC 1333

    We observed the clustered star forming complex NGC 1333 with the BIMA and FCRAO telescopes in the transitions HCO+(1-0) and N_2_H+(1-0) over an area with resolution ~10"...
  • Radio properties of optically selected quasars

    Approximately one-quarter (256 objects) of the Large Bright Quasar Survey (LBQS, Hewett et al., 1995, Cat. ) has been observed with the VLA at 8.4GHz, resulting in 44 detections...
  • Proper motions and brightness of Cas A

    The results of a multiple-epoch radio study of secular changes in the SNR Cassiopeia A are reported and used to construct a model for the dynamical evolution of diffuse and...
  • Radio structure in z~0.25 radio-quiet QSOs

    We present analysis of a homogeneous, optically selected, volume-limited (0.2<z<0.3) sample of 128 radio-quiet quasi-stellar objects (QSOs) recently observed at 6GHz with...
  • X-band observation of compact radio sources in M17

    We present a catalog of radio sources of the M17 region based on deep X-band radio observations centered at 10GHz obtained with the Jansky Very Large Array in the A...
  • MOJAVE. XIII. New 15GHz observations on 1994-2013

    We present 1625 new 15GHz (2cm) VLBA images of 295 jets associated with active galactic nuclei (AGNs) from the MOJAVE and 2cm VLBA surveys, spanning observations between 1994...
