Mapping feedback signatures in 3C 297: A quasar-host merger at Cosmic Noon
Chetna Duggal, Christopher P. O'Dea, Stefi A. Baum +6
We present a study of quasar host galaxy 3C 297 which is home to a powerful bent-jet radio source suggesting vigorous interaction with a dense ISM and/or jet precession. Archival H…
Powerful Radio-Loud Quasars are Triggered by Galaxy Mergers in the Cosmic Bright Ages
Peter Breiding, Marco Chiaberge, Erini Lambrides +14
While supermassive black holes are ubiquitous features of galactic nuclei, only a small minority are observed during episodes of luminous accretion. The physical mechanism(s) drivi…
The puzzling case of the radio-loud QSO 3C 186: a gravitational wave recoiling black hole in a young radio source?
M. Chiaberge, J. C. Ely, E. T. Meyer +14
Context. Radio-loud AGNs with powerful relativistic jets are thought to be associated with rapidly spinning black holes (BHs). BH spin-up may result from a number of processes, inc…
Chandra Observations of 3C Radio Sources with z<0.3 II: completing the snapshot survey
F. Massaro, G. R. Tremblay, D. E. Harris +14
We report on the second round of Chandra observations of the 3C snapshot survey developed to observe the complete sample of 3C radio sources with z<0.3 for 8 ksec each. In the firs…
An optical spectroscopic survey of the 3CR sample of radio galaxies with z<0.3. IV. Discovery of the new spectroscopic class of relic radio galaxies
Alessandro Capetti, Sara Buttiglione, David J. Axon +6
From an optical spectroscopic survey of 3CR radio galaxies with z<0.3, we discovered a new spectroscopic class of powerful radio-loud AGN. The defining characteristics of these gal…
The 1.6 micron near infrared nuclei of 3C radio galaxies: Jets, thermal emission or scattered light?
R. D. Baldi, M. Chiaberge, A. Capetti +6
Using HST NICMOS 2 observations we have measured 1.6-micron near infrared nuclear luminosities of 100 3CR radio galaxies with z<0.3, by modeling and subtracting the extended emissi…
What do HST and Chandra tell us about the jet and the nuclear region of the radio galaxy 3C270?
Marco Chiaberge, Roberto Gilli, F. Duccio Macchetto +2
The HST/STIS ultraviolet image of the FR I radio galaxy 3C270 shows the presence of a jet-like structure emerging from the position of the nucleus. This feature, which represents t…
The nuclei of radio galaxies in the UV: the signature of different emission processes
Marco Chiaberge, F. Duccio Macchetto, William B. Sparks +3
We have studied the nuclei of 28 radio galaxies from the 3CR sample in the UV band. Unresolved nuclei (central compact cores, CCC) are observed in 10 of the 13 FR I, and in 5 of th…
Ultraviolet HST Snapshot Survey of 3CR Radio Source Counterparts at Low Redshift
Mark G. Allen, William B. Sparks, Anton Koekemoer +6
We present ultraviolet images of 27 3CR radio galaxies with redshifts z<0.1 that have been imaged with the Space Telescope Imaging Spectrograph (STIS) on board the Hubble Space Tel…
Filaments and Ionized Gas in the Vicinity of 3C 244.1
Carlos Feinstein, F. Duccio Macchetto, Andre R. Martel +1
We present results of Hubble Space Telescope observations of the radio galaxy 3C 244.1. The broadband F702W (R) and F555W (V) images (WFPC2/PC) show an elliptical galaxy and gaseou…
Optical and Radio Polarimetry of the M87 Jet at 0.2" Resolution
Eric S. Perlman, John A. Biretta, Fang Zhou +2
We discuss optical (HST/WFPC2 F555W) and radio (15 GHz VLA) polarimetry observations of the M87 jet taken during 1994-1995. Many knot regions are very highly polarized ($\sim 40-50…
