A VLBA Search for a Stimulated Recombination Line from the Accretion Region in NGC1275
R. C. Walker, K. R. Anantharamaiah
The radio source 3C84, in NGC1275, has a two sided structure on parsec scales. The northern feature, presumed to be associated with a jet moving away from the Earth, shows strong e…
Radio-selected Galaxies in Very Rich Clusters at z < 0.25: II. Radio Properties and Analysis
Glenn E. Morrison, Frazer N. Owen
(Abridged) We report on the properties of radio-selected galaxies within 30 very-rich Abell clusters with z < 0.25. These radio data sample the ultra-faint (L(1.4) > 2E22 W/Hz) rad…
Massive Ellipticals at High Redshift: NICMOS Imaging of Z~1 Radio Galaxies
A. W. Zirm, M. Dickinson, A. Dey
We present deep, continuum images of eleven high-redshift (0.811 < z < 1.875) 3CR radio galaxies observed with NICMOS. Our images probe the rest-frame optical light where stars are…
X-ray Spectroscopic Evidence for Intermediate Mass Black Holes: Cool Accretion Disks in Two Ultra--Luminous X-ray Sources
J. M. Miller, G. Fabbiano, M. C. Miller +1
We have analyzed an XMM-Newton observation of the nearby spiral galaxy NGC 1313, which contains two "ultra-luminous" X-ray (ULX) sources. We measure isotropic luminosities of L_X =…
High frequency quasi-periodic oscillations in the black hole X-ray transient XTE J1650-500
Jeroen Homan, Marc Klein-Wolt, Sabrina Rossi +5
We report the detection of high frequency variability in the black hole X-ray transient XTE J1650-500. A quasi-periodic oscillation (QPO) was found at 250 Hz during a transition fr…
Clustered Star Formation in W75 N
D. S. Shepherd, L. Testi, D. P. Stark
We present 2" to 7" resolution 3 mm continuum and CO(J=1-0) line emission and near infrared Ks, H2, and [FeII] images toward the massive star forming region W75 N. The CO emission…
