The ROSAT Brightest Cluster Sample — I. The compilation of the sample and the cluster log N—log S distribution
We present a 90 per cent flux-complete sample of the 201 X-ray-brightest clusters of galaxies in the northern hemisphere (δ ≥ 0°), at high Galactic latitudes (|b| ≥ 20°), with measured redshifts z ≤
The ROSAT Brightest Cluster Sample - IV. The extended sample
We present a low-flux extension of the X-ray-selected ROSAT Brightest Cluster Sample (BCS) published in Paper I of this series. Like the original BCS and employing an identical selection procedure,
A ROSAT study of the cores of clusters of galaxies — I. Cooling flows in an X-ray flux-limited sample
ABSTRA C T This is the first part of a study of the detailed X-ray properties of the cores of nearby clusters. We have used the flux-limited sample of 55 clusters listed by Edge et al., and archival
The relation between accretion rate and jet power in X-ray luminous elliptical galaxies
Using Chandra X-ray observations of nine nearby, X-ray luminous elliptical galaxies with good optical velocity dispersion measurements, we show that a tight correlation exists between the Bondi
The Observed Growth of Massive Galaxy Clusters II: X-ray Scaling Relations
This is the second in a series of papers in which we derive simultaneous constraints on cosmology and X-ray scaling relations using observations of massive, X-ray flux-selected galaxy clusters. The
A very deep Chandra observation of the Perseus cluster: shocks, ripples and conduction
We present the first results from a very deep Chandra X-ray observation of the core of the Perseus cluster of galaxies. A pressure map reveals a clear thick band of high pressure around the inner
Chandra imaging of the complex X-ray core of the Perseus cluster
ABSTRACT We report subarcsec-resolution X-ray imaging of the core ofthe Perseus cluster around thegalaxy NGC1275 with the Chandra X-ray Observatory. The ROSAT-discovered holes asso-ciated with the
A deep Chandra observation of the Perseus cluster: shocks and ripples
We present preliminary results from a deep observation lasting almost 200 ks of the centre of the Perseus cluster of galaxies around NGC 1275. The X-ray surface brightness of the intracluster gas
The ROSAT Brightest Cluster Sample — III. Optical spectra of the central cluster galaxies
We present new spectra of dominant galaxies in X-ray selected clusters of galaxies, which combine with our previously published spectra to form a sample of 256 dominant galaxies in 215 clusters. 177
Chandra X-ray observations of the giant elliptical galaxy M87 resolve the thermal state of the hot interstellar medium into the accretion (Bondi) radius of its central 3 × 109 M☉ black hole. We
