The X-ray emission of 3C 346 and its environment
D. M. Worrall, M. Birkinshaw
We present a detailed spectral and spatial analysis of the X-ray properties of the compact and unusual radio galaxy 3C 346, combining information from ROSAT and ASCA. The dominant…
Tunable-filter imaging of quasar fields at z~1. I. A cluster around MRC B0450-221
Joanne C. Baker, Richard W. Hunstead, Malcolm N. Bremer +3
Using a combination of multicolour broad- and narrow-band imaging techniques and follow-up spectroscopy, we have detected an overdensity of galaxies in the field of quasar MRC B045…
Diffuse Cluster-wide Radio Halos
Haida Liang
We will discuss the properties and origins of halos and relics including estimates of the cluster magnetic fields, and present results for a few recently discovered halos and relic…
The XMM-Newton Serendipitous Survey I. The role of XMM-Newton Survey Science Centre
M. G. Watson
This paper describes the performance of XMM-Newton for serendipitous surveys and summarises the scope and potential of the XMM-Newton Serendipitous Survey. The role of the Survey S…
XMM-Newton observations of M87 and Its X-Ray Halo
H. Boehringer, E. Belsole, J. Kennea +10
We report performance verification observations of the giant elliptical galaxy M87 in the Virgo Cluster with the MOS, pn, and optical monitor instruments on board of XMM-Newton. Wi…
An XMM-Newton study of the sub-structure in M87's halo
E. Belsole, J. L. Sauvageot, H. Bohringer +9
The high signal to noise and good point spread function of XMM have allowed the first detailed study of the interaction between the thermal and radio emitting plasma in the central…
Probing the gravitational potential of a nearby lensing cluster Abell 2104
H. Liang, L. Lemonon, I. Valtchanov +2
The cluster Abell 2104 is one of the lowest redshift clusters (z=0.153) known to have a gravitational lensing arc. We present detailed analysis of the cluster properties such as th…
Infrared Spectra of Cooling Flow Galaxies
W. Jaffe, M. N. Bremer, P. P. van der Werf
We have taken K-band spectra covering 7 cooling flow clusters. The spectra show many of the 1-0S transitions of molecular Hydrogen, as well as some of the higher vibrational transi…
Morphological Number Counts and Redshift Distributions to I = 25 from the Hubble Deep Fields: Constraints on Cosmological Models from Early Type Galaxies
S. Phillipps, S. P. Driver, W. J. Couch +5
We combine magnitude and photometric redshift data on galaxies in the Hubble Deep Fields with morphological classifications in order to separate out the distributions for early typ…
85-GHz BIMA observations of the double-hotspot radio galaxy 3C20
M. J. Hardcastle, L. W. Looney
We present 85-GHz observations of the archetypal double-hotspot radio source 3C20 made with the BIMA millimetre array. The resolution of BIMA allows us to separate the two componen…
The environments of FRII radio sources
M. J. Hardcastle, D. M. Worrall
Using ROSAT observations, we estimate gas pressures in the X-ray-emitting medium surrounding 63 FRII radio galaxies and quasars. We compare these pressures with the internal pressu…
A Powerful Radio Halo in the Hottest Known Cluster of Galaxies 1E0657-56
H. Liang, R. W. Hunstead, M. Birkinshaw +1
We report the detection of a diffuse radio halo source in the hottest known cluster of galaxies 1E0657-56 (RXJ0658-5557). The radio halo has a morphology similar to the X-ray emiss…
The Infrared Jet In 3C66B
D. Tansley, M. Birkinshaw, M. J. Hardcastle +1
We present images of infrared emission from the radio jet in 3C66B. Data at three wavelengths (4.5, 6.75 and 14.5 microns) were obtained using the Infrared Space Observatory. The 6…
Chandra Discovery of a 100 kpc X-ray Jet in PKS 0637--752
D. A. Schwartz, H. L. Marshall, J. E. J. Lovell +18
The quasar PKS 0637-753, the first celestial X-ray target of the Chandra X-ray Observatory, has revealed asymmetric X-ray structure extending from 3 to 12 arcsec west of the quasar…
The Chandra X-ray Observatory Resolves the X-ray Morphology and Spectra of a Jet in PKS 0637-752
G. Chartas, D. M. Worrall, M. Birkinshaw +14
The core-dominated radio-loud quasar PKS 0637-752 (z = 0.654) was the first celestial object observed with the Chandra X-ray Observatory, offering the early surprise of the detecti…
A spectroscopic study of NGC 6251 and its companion galaxies
P. N. Werner, D. M. Worrall, M. Birkinshaw
Measurements of the velocities of galaxies thought to be associated with the giant radio galaxy NGC 6251 confirm the presence of a poor cluster with a systemic redshift of z= 0.024…
