Suzaku Observations of the Radio Galaxy 3C 33 (2009)
Evans, Daniel A., Reeves, James N., Hardcastle, Martin J., Kraft, Ralph P., Lee, Julia C., Virani, Shanil N.
We present results from a new 100-ks Suzaku observation of the nearby radio galaxy 3C 33, and investigate the nature of absorption, reflection, and jet production in this source. We model the 2-70...
Luminosity functions of LMXBs in Centaurus A: globular clusters versus the field (2009)
Voss, Rasmus, Gilfanov, Marat, Sivakoff, Gregory R., Kraft, Ralph P., Jordan, Andres, Raychaudhury, Somak, ...
GMRT study of X-shaped radio sources (2008)
Lal, Dharam Vir, Rao, A. Pramesh, Hardcastle, Martin J., Cheung, C. C., Bhatnagar, Sanjay, Kraft, Ralph P., ...
Context. The nature of X-shaped sources is a matter of considerable debate in the literature: it has even been proposed that they provide evidence for black-hole-mergers/spin-reorientation, and...
"Normal" FRII Radio Galaxies as a Probe of the Nature of X-Shaped Radio Sources (2008)
Lal, Dharam Vir, Hardcastle, Martin J., Kraft, Ralph P.
We present a multiwavelength radio study of a sample of nearby Fanaroff-Riley class II (FRII) radio galaxies, matched with the sample of known X-shaped radio sources in size, morphological properties...
XMM-Newton Observations of the Nuclei of the Radio Galaxies 3C 305, DA 240, and 4C 73.08 (2008)
Evans, Daniel A., Hardcastle, Martin J., Lee, Julia C., Kraft, Ralph P., Worrall, Diana M., Birkinshaw, Mark, ...
We present new XMM-Newton EPIC observations of the nuclei of the nearby radio galaxies 3C 305, DA 240, and 4C 73.08, and investigate the origin of their nuclear X-ray emission. The nuclei of the...
A Transient Black-Hole Low-Mass X-Ray Binary Candidate in Centaurus A (2008)
Sivakoff, Gregory R., Kraft, Ralph P., Jordán, Andrés, Juett, Adrienne M., Evans, Daniel A., Forman, William R., ...
We report the discovery of a bright transient X-ray source, CXOU J132518.2-430304, towards Centaurus A (Cen A) using six new Chandra X-Ray Observatory observations in 2007 March--May. Between 2003...
Globular Clusters and X-ray Point Sources in Centaurus A (NGC 5128) (2008)
Woodley, Kristin A., Raychaudhury, Somak, Kraft, Ralph P., Harris, William E., Jordan, Andres, Whitaker, Katherine E., ...
We detect 353 X-ray point sources, mostly low-mass X-ray binaries (LMXBs), in four Chandra observations of Centaurus A (NGC 5128), the nearest giant early-type galaxy, and correlate this point source...
A Radio Through X-ray Study of the Jet/Companion-Galaxy Interaction in 3C 321 (2007)
Evans, Daniel A., Fong, Wen-Fai, Hardcastle, Martin J., Kraft, Ralph P., Lee, Julia C., Worrall, Diana M., ...
We present a multiwavelength study of the nucleus, environment, jets, and hotspots of the nearby FRII radio galaxy 3C 321, using new and archival data from MERLIN, the VLA, Spitzer, HST, and Chandra....
Low-Mass X-ray Binaries and Globular Clusters in Centaurus A (2007)
Jordan, Andres, Sivakoff, Gregory R., McLaughlin, Dean E., Blakeslee, John P., Evans, Daniel A., Kraft, Ralph P., ...
We present results of Hubble Space Telescope and Chandra X-ray Observatory observations of globular clusters (GCs) and low-mass X-ray binaries (LMXBs) in the central regions of Centaurus A. Out of...
Andrés Jordán, Gregory R. Sivakoff, Dean E. Mclaughlin, John P. Blakeslee, Daniel A. Evans, Ralph P. Kraft, ...
We present results of Hubble Space Telescope and Chandra X-Ray Observatory observations of globular clusters (GCs) and low-mass X-ray binaries (LMXBs) in the central regions of Centaurus A. Out of...
Evans, Daniel A., Lee, Julia C., Kamenetska, Maria, Gallagher, Sarah C., Kraft, Ralph P., Hardcastle, Martin J., ...
We present results from new Chandra and archival HST and VLA imaging observations of the circumnuclear extended emission in the nearby Type 2 Seyfert galaxy NGC 2110. We find resolved soft-band X-ray...
