Star formation in hosts of young radio galaxies
A. Labiano, C. P. O'Dea, P. D. Barthel +2
We present near ultraviolet imaging with the Hubble Space Telescope Advanced Camera for Surveys, targeting young radio galaxies (Gigahertz Peaked Spectrum and Compact Steep Spectru…
The Jet and Circumnuclear Environment of 3C 293
David J. E. Floyd, Eric Perlman, J. Patrick Leahy +5
We present the new HST near-infrared polarimetry, broad and narrow-band imaging, and MERLIN 4.5GHz Multi-Frequency Synthesis radio imaging of 3C 293, a unique radio galaxy whose ho…
The Warped Nuclear Disk of Radio Galaxy 3C 449
Grant R. Tremblay, Alice C. Quillen, David J. E. Floyd +11
Among radio galaxies containing nuclear dust disks, the bipolar jet axis is generally observed to be perpendicular to the disk major axis. The FR I radio source 3C 449 is an outlie…
Two Clusters with Radio-quiet Cooling Cores
Megan Donahue, G. Mark Voit, Christopher P. O'Dea +2
Radio lobes inflated by active galactic nuclei at the centers of clusters are a promising candidate for halting condensation in clusters with short central cooling times because th…
Resolving the Shocks in Radio Galaxy Nebulae: HST and Radio Imaging of 3C 171, 3C277.3 and PKS2250-41
Avanti Tilak, Christopher P. O'Dea, Clive Tadhunter +5
We present the results of HST/WFPC2 medium and narrow band imaging and VLA and MERLIN2 radio imaging of three powerful radio galaxies: 3C 171, 3C 277.3, and PKS 2250-41. We obtaine…
HST/STIS Spectroscopy of the Lyman-Alpha Emission Line in the Central Dominant Galaxies in A426, A1795, and A2597: Constraints on Clouds in the Intracluster Medium
S. A. Baum, A. Laor, C. P. O'Dea +2
We report on HST/STIS spectra of the Lyman-alpha emission in the central dominant galaxies in three rich clusters of galaxies. We find evidence for a population of clouds in the in…
