    GMRT detection of HI 21 cm-line absorption from the peculiar galaxy in Abell 2125

    Using the recently completed Giant Meterwave Radio Telescope, we have detected the HI 21 cm-line absorption from the peculiar galaxy C153 in the galaxy cluster Abell 2125. The HI absorption is at a redshift of...

    Hst Observations of Abell 2125: Radio Emission and the Butcher-Oemler Effect

    We have surveyed more than 40 Abell clusters at redshifts z ≥ 0.2 with the VLA at 20cm down to radio powers of P20cm ~ 1022 W Hz-1. For P20cm > 1023, the radio luminosity function (RLF) is dominated by nuclear/AG...

    Butcher-Oemler Effect and Radio Continuum

    The Abell clusters 2125 and 2645 have been imaged in the radio at 20 cm to the same luminosity limit using the Very Large Array. Both the clusters are very similar in richness and redshift, but Abell 2125 has ...

    Radio Sources in Clusters of Galaxies

    Since the Albuquerque IAU meeting, most of the advances in the understanding of radio sources in clusters has come from combining radio observations with x-ray and optical data. The x-ray images from Einstein and...

    Preliminary Results of the 20-CM VLA Survey of Abell Clusters

    During the past three years, we have been conducting a 20-cm radio frequency continuum survey of Abell clusters using the NRAO VLA. The survey consists of clusters which meet the following criteria:

      A Comparison of the Structures of 3CR Quasars and Blank Field Radio Sources

      The purpose of this communication is to update our knowledge of the radio structural properties of quasars and blank field radio sources (blank field ≡ any radio source without an identification on the Palomar...

      VLBI Observations of M87

      On 1980 February 20 we conducted an 8-station intercontental VLBI experiment in order to study the nucleus and jet of M87 at 1666.6 MHz in right circular polarization. Our array was sensitive to structures fro...

      Redshift Estimates for Distant Radio Galaxies Based on Broadband Photometry

      Calculations modeling the effects of stellar evolution on elliptical galaxies (e.g., Bruzual and Kron 1980, Bruzual 1981) suggest that the shape of the spectral flux distribution should remain almost constant ...
