The z=0.0912 and z=0.2212 Damped Lyman Alpha Galaxies Along the Sight-Line Toward the Quasar OI 363
D. A. Turnshek, S. Rao, D. Nestor +4
New optical and infrared observations along the sight-line toward the quasar OI 363 (0738+313) are presented and discussed. Excluding systems which lack confirming UV spectroscopic…
HI 21cm absoprtion in two low redshift damped Ly-alpha systems
W. Lane, A. Smette, F. Briggs +3
We report the discovery of two low redshift HI 21cm absorbers, one at z = 0.2212 towards the z_{em} = 0.630 quasar OI 363 (B0738+313), and the other at z = 0.3127 towards PKS B1127…
Deep 1.4 GHZ Follow Up of the Steep Spectrum Radio Halo in Abell 521
D. Dallacasa, G. Brunetti, S. Giacintucci +6
In a recent paper we reported on the discovery of a radio halo with very steep spectrum in the merging galaxy cluster Abell 521 through observations with the Giant Metrewave Radio…
A low-frequency radio halo associated with a cluster of galaxies
G. Brunetti, S. Giacintucci, R. Cassano +7
Clusters of galaxies are the largest gravitationally bound objects in the Universe, containing about 10^15 solar masses of hot (10^8 K) gas, galaxies and dark matter in a typical v…
Low-frequency study of two giant radio galaxies: 3C35 and 3C223
E. Orrù, M. Murgia, L. Feretti +5
Radio galaxies with a projected linear size > 1 Mpc are classified as giant radio sources. According to the current interpretation these are old sources which have evolved in a low…
Damped Lyman-Alpha Galaxies
D. Turnshek, S. Rao, W. Lane +4
Some results from an imaging program to identify low-redshift (0.09<z<1.63) damped Lyman-alpha (DLA) galaxies are presented. The standard paradigm that was widely accepted a decade…
Thermal and Non-thermal Plasmas in the Galaxy Cluster 3C 129
H. Krawczynski, D. E. Harris, R. Grossman +3
We describe new Chandra spectroscopy data of the cluster which harbors the prototypical "head tail" radio galaxy 3C 129 and the weaker radio galaxy 3C 129.1. We combined the Chandr…
First Light for the First Station of the Long Wavelength Array
G. B. Taylor, S. W. Ellingson, N. E. Kassim +32
The first station of the Long Wavelength Array (LWA1) was completed in April 2011 and is currently performing observations resulting from its first call for proposals in addition t…
