  • A deep radio survey of Abell 2125. I

    We present a description of deep radio, optical, and near-IR observations taken with the VLA, the KPNO 2m telescope, and the KPNO 4m telescope of the region containing the rich...
  • Third VLBA calibrator survey: VCS3

    We present the third extension to the Very Long Baseline Array (VLBA) Calibrator Survey, containing 360 new sources not previously observed with Very Long Baseline...
  • Sgr A* variability at cm wavelengths

    We present the results of a 3.3yr project to monitor the flux density of Sagittarius A at 2.0, 1.3, and 0.7cm with the Very Large Array. Between 2000.5 and 2003.0, 119 epochs of...
  • Second VLBA calibrator survey: VCS2

    This paper presents an extension of the Very Long Baseline Array Calibrator Survey, called VCS2, containing 276 sources. This survey fills in regions of the sky that were not...
  • Chandra Deep Field North survey. XII

    We investigate the relationship between faint X-ray and 1.4GHz radio source populations detected within 3' of the Hubble Deep Field (North) using the 1Ms Chandra (Cat. ) and...
  • 1.4 GHz imaging of the Bootes field

    We present the results from our deep (16x12hr) Westerbork Synthesis Radio Telescope (WSRT) observations of the approximately 7{deg}^2^ Bootes Deep Field, centered at 14h 32min...
  • Radio sources in Abell 2125 and 2645

    The Abell clusters 2125 and 2645 have different radio source populations, despite being very similar in richness (Abell class 4) and redshift (0.25). The number density of radio...
  • New quasar radio detections

    Using the NVSS radio catalog, we have searched for radio emission from 4079 quasars taken from the 1996 version of the Veron-Cetty & Veron [ESO Scientific Report No.X (1996,...
  • The FIRST bright QSO survey

    The FIRST radio survey provides a new resource for constructing a large quasar sample. With source positions accurate to better than 1" and a point source sensitivity limit of...
  • Radio reference frame

    A catalogue is presented based on the radio positions of 436 extragalactic sources distributed over the entire sky. The positional accuracy of the sources is better than 3...
  • Extragalactic IRAS sources

    Extragalactic sources detected at lambda=60um were selected from the IRAS Faint Source Catalog, Version 2 (Cat. II/156) by the criterion S(60um)>=S(12um). They were...
  • Steep spectrum radio spectra sources

    (no description available) Cone search capability for table J/A+AS/91/337/table2 (A list of steep spectrum radio sources)
  • Compact radio sources near l=140, b=0

    (no description available)
  • RATAN-600 7.6 cm catalog of radio sources

    A catalog containing 840 radio sources obtained during the Experiment Cold-80 at 7.6 cm wavelength using RATAN-600 are presented. The completeness of the list in the central...
  • 11cm radio continuum survey. IV.

    We analysed the 11cm Galactic Plane survey carried out with the Effelsberg 100-m telescope for small diameter sources. We present a list of 6483 radio sources with a maximum...
  • 21cm radio continuum survey. I.

    The 21 cm Galactic Plane survey was carried out with the Effelsberg 100-m radio telescope (HPBW = 9.4'). It contains sources from l=357{deg} to l=95.5{deg} and from...
  • Spectral index for B3 radio sources

    Flux density measurements at 4730MHz are presented for a sample of 770 radio sources from the B3 catalogue with density S408>0.35Jy. For 429 of these sources flux density...
  • The 64W part of the WRST Survey

    We present a deep 92cm survey down to 4.5mJy (5{sigma}) carried out with the Westerbork Synthesis Radio Telescope (WSRT) of a field in Lynx, previously observed at three other...
  • The 65W part of the WSRT 21 cm survey in Lynx

    Observations of the field Lynx 3A, obtained at 21cm with 5{sigma} peak flux 85{mu}Jy using the 3-km array of the Westerbork Synthesis Radio Telescope for 16x12h periods during...
  • 22MHz flux densities of radio sources

    table1 is a compilation of the flux densities at 22.25MHz for 395 sources, derived from three or more observations of each source. The source were measured over a period of...
