Dynamical, physical, and chemical properties of emission-line nebulae in cooling flows
The results are reported of a program of long-slit spectroscopy, narrow-band imaging, and VLA mapping of the optical emission-line gas and nonthermal radio continuum emission associated with the
A sample of 669 ultra steep spectrum radio sources to find high redshift radio galaxies
Since radio sources with Ultra Steep Spectra (USS; . 1:30;S / ) are ecient tracers of high redshift radio galaxies (HzRGs), we have dened three samples of such USS sources using the recently com-
Triggered Star Formation in a Massive Galaxy at z = 3.8: 4C 41.17
We present deep spectropolarimetric observations obtained with the W. M. Keck Telescope of the very high redshift (z=3.79786{plus_minus}0.0024) radio galaxy 4C 41.17. We find that the bright,
The subluminous spectroscopically peculiar type Ia supernova 1991bg in the elliptical galaxy NGC 4374
We present photometric and spectroscopic observations of SN 1991bg, a very peculiar Type Ia supernova located in the outskirts of the E1 galaxy NGC 4374 (M84) in the Virgo cluster. At maximum
Radio continuum imaging of high-redshift radio galaxies
We present sensitive radio continuum observations at high resolution of 37 radio galaxies at z > 2. The observations were made with the Very Large Array (VLA) at 4.7 and 8.2 GHz, with typical
Protoclusters associated with z > 2 radio galaxies - I. Characteristics of high redshift protoclusters
We present the results of a large program conducted with the Very Large Telescope and augmented by observations with the Keck telescope to search for forming clusters of galaxies near powerful radio
The Hy-Redshift Universe: Galaxy Formation and Evolution at High Redshift
Hyron Spinrad's career has spanned several decades, and has stretched from our neighboring planets to the most remote galaxies in the Universe, pausing in between to ''enrich'' our knowledge of the
Deep Westerbork 1.4 GHz imaging of the Bootes field
We present the results from our deep (16 × 12 hr) Westerbork Synthesis Radio Telescope (WSRT) observations of the approximately 7 deg2 Bootes Deep Field, centered at 14h32m0575, 34°16'475 (J2000.0).
Spatially resolved optical images of high-redshift quasi-stellar objects
U and B continuum and Ly-alpha images obtained with the UV-flooded TI2 CCD at the prime focus of the 4-m telescope at KPNO during May and November 1988 are reported for 19 radio-loud high-redshift
