Polarization and variability of compact sources measured in Planck time-ordered data
G. Rocha, R. Keskitalo, B. Partridge +4
This paper introduces a new Planck Catalog of Polarized and Variable Compact Sources (PCCS-PV) comprising 153 sources, the majority of which are extragalactic. The data include bot…
The Mass Distribution of the Unusual Merging Cluster Abell 2146 from Strong Lensing
Joseph E. Coleman, Lindsay J. King, Masamune Oguri +11
Abell 2146 consists of two galaxy clusters that have recently collided close to the plane of the sky, and it is unique in showing two large shocks on $\textit{Chandra X-ray Observa…
A Ten Billion Solar Mass Outflow of Molecular Gas Launched by Radio Bubbles in the Abell 1835 Brightest Cluster Galaxy
B. R. McNamara, H. R. Russell, P. E. J. Nulsen +17
We report ALMA Early Science observations of the Abell 1835 brightest cluster galaxy (BCG) in the CO (3-2) and CO (1-0) emission lines. We detect 5E10 solar masses of molecular gas…
Misalignment of the Jet and the Normal to the Dusty Torus in the Broad Absorption Line QSO FIRST\,J155633.8+351758
Cormac Reynolds, Brian Punsly, Christopher O'Dea
We performed VLBA observations of the Broad Absorption Line Quasar FIRST\,J155633.8+351758, "the first radio loud BALQSO". Our observations at 15.3 GHz partially resolved a seconda…
Hubble Space Telescope Observations of Dusty Filaments in Hercules A: Evidence for Entrainment
Christopher P. O'Dea, Stefi A. Baum, Grant R. Tremblay +3
We present U, V, and I-band images of the host galaxy of Hercules A (3C 348) obtained with HST/WFC3/UVIS. We find a network of dusty filaments which are more complex and extended t…
Polarimetry and the High-Energy Emission Mechanisms in Quasar Jets. The Case of PKS 1136-135
Mihai Cara, Eric S. Perlman, Yasunobu Uchiyama +11
Since the discovery of kiloparsec-scale X-ray emission from quasar jets, the physical processes responsible for their high-energy emission have been poorly defined. A number of mec…
Star formation in luminous quasar host galaxies at z=1-2
David J. E. Floyd, James S. Dunlop, Marek J. Kukula +4
We present deep HST/WFPC2, rest-frame U images of 17 ~L* quasars at z=1 and z=2 (V and I bands respectively), designed to explore the host galaxies. We fit the images with simple a…
The nature of the jet-driven outflow in the radio galaxy 3C305
M. J. Hardcastle, F. Massaro, D. E. Harris +6
We present Chandra X-ray and VLA radio observations of the radio galaxy 3C305. The X-ray observations reveal the details of the previously known extended X-ray halo around the radi…
The Relationship Between Beam Power and Radio Power for Classical Double Radio Sources
Ruth A. Daly, Trevor B. Sprinkle, Christopher P. O'Dea +2
Beam power is a fundamental parameter that describes, in part, the state of a supermassive black hole system. Determining the beam powers of powerful classical double radio sources…
Herschel observations of the Centaurus cluster - the dynamics of cold gas in a cool core
Rupal Mittal, Christopher P. O'Dea, Gary Ferland +15
Brightest cluster galaxies (BCGs) in the cores of galaxy clusters have distinctly different properties from other low redshift massive ellipticals. The majority of the BCGs in cool…
Herschel photometry of brightest cluster galaxies in cooling flow clusters
A. C. Edge, J. B. R. Oonk, R. Mittal +24
The dust destruction timescales in the cores of clusters of galaxies are relatively short given their high central gas densities. However, substantial mid-infrared and sub-mm emiss…
Herschel observations of FIR emission lines in brightest cluster galaxies
A. C. Edge, J. B. R. Oonk, R. Mittal +24
The question of how much gas cools in the cores of clusters of galaxies has been the focus of many, multiwavelength studies in the past 30 years. In this letter we present the firs…
Chandra observation of two shock fronts in the merging galaxy cluster Abell 2146
H. R. Russell, J. S. Sanders, A. C. Fabian +5
We present a new Chandra observation of the galaxy cluster Abell 2146 which has revealed a complex merging system with a gas structure that is remarkably similar to the Bullet clus…
Episodic Star Formation Coupled to Reignition of Radio Activity in 3C 236
Grant R. Tremblay, Christopher P. O'Dea, Stefi A. Baum +4
We present Hubble Space Telescope UV and optical imaging of the radio galaxy 3C 236, whose relic 4 Mpc radio jet lobes and inner 2 kpc CSS radio source are evidence of multiple epo…
Hubble Space Telescope Near Infrared Snapshot Survey of 3CR radio source counterparts III: Radio galaxies and quasars in context
David J. E. Floyd, David Axon, Stefi Baum +6
We compare the near-infrared (NIR) H band photometric and morphological properties of low-redshift (z<0.3) 3CR radio galaxies with samples of BL Lac object and quasar host galaxies…
A Detailed Study of the Lobes of Eleven Powerful Radio Galaxies
Ruth A. Daly, Preeti Kharb, Christopher P. O'Dea +5
Radio lobes of a sample of eleven very powerful classical double radio galaxies were studied. Each source was rotated so that the symmetry axis of the source was horizontal, and ve…
