We employ an ensemble of 24 hydrodynamic cluster simulations to create spatially and spectrally resolved images of quality comparable to Chandra's expected performance. Emission from simulation mass elements is represented using the XSPEC "MEKAL" program assuming 0.3 solar metallicity and the resulting spectra are fitted with a single-temperature model. Despite significant departures from isothermality in the cluster gas, single-temperature models produce acceptable fits to 20,000 source photon… 

Mismatch between X-Ray and Emission-weighted Temperatures in Galaxy Clusters: Cosmological Implications

The thermal properties of hydrodynamical simulations of galaxy clusters are usually compared to observations by relying on the emission-weighted temperature Tew instead of on the spectroscopic X-ray

Effects of Preheating on X-Ray Scaling Relations in Galaxy Clusters

The failure of purely gravitational and gasdynamical models of X-ray cluster formation to reproduce basic observed properties of the local cluster population suggests the need for one or more

A simulated τCDM cosmology cluster catalogue: the NFW profile and the temperature-mass scaling relations

We have extracted over 400 clusters, covering more than two decades in mass, from three simulations of the tauCDM cosmology. This represents the largest uniform catalogue of simulated clusters ever

The power spectrum amplitude from clusters revisited: σ8 using simulations with pre-heating and cooling

The amplitude of density perturbations, for the currently-favoured ACDM cosmology, is constrained using the observed properties of galaxy clusters. The catalogue used is that of Ikebe et al. The


Using a hydrodynamics plus N-body simulation of galaxy cluster formation within a large volume and mock Chandra X-ray observations, we study the form and evolution of the intrinsic scatter about the


Analyses of cosmological hydrodynamic simulations of galaxy clusters suggest that X-ray masses can be underestimated by 10% to 30%. The largest bias originates by both violation of hydrostatic

Chandra X-Ray Spectroscopy and Imaging of the Galaxy Cluster PKS 0745–191

We present a detailed spectral and spatial analysis of the galaxy cluster PKS 0745-191, using recent observations from the Chandra X-Ray Observatory. The data provide information on the temperature

The effect of formation redshifts on the cluster mass–temperature relation

I employ an ensemble of hydrodynamical simulations and the XSPEC MEKAL emission model to reproduce observable spectral and flux-weighted temperatures for 24 clusters. Each cluster is imaged at 16

Simulating the soft X-ray excess in clusters of galaxies

The detection of an excess of soft X-ray or Extreme Ultraviolet (EUV) radiation, above the thermal contribution from the hot intracluster medium (ICM), has been a controversial subject ever since the



Properties of the Intracluster Medium in an Ensemble of Nearby Galaxy Clusters

We present a systematic analysis of the intracluster medium (ICM) in an X-ray flux limited sample of 45 galaxy clusters. Using archival ROSAT Position-Sensitive Proportional Counter (PSPC) data and

The LX—T relation and intracluster gas fractions of X-ray clusters

We re-examine the X-ray luminosity–temperature relation using a nearly homogeneous data set of 24 clusters selected for statistically accurate temperature measurements and absence of strong cooling

Simulations of X-ray clusters

We present simulations of the formation and evolution of galaxy clusters in the Cold Dark Matter cosmogony. Clusters with a wide range of mass were selected from previous N-body models, and were

The Effects of Clumping and Substructure on Intracluster Medium Mass Measurements

We examine an ensemble of 48 simulated clusters to determine the effects of small-scale density fluctuations and large-scale substructure on X-ray measurements of the intracluster medium (ICM) mass.

A catalog of intracluster gas temperatures

We have searched the Einstein Monitor Proportional Counter (MPC) data base for observations of clusters of galaxies. By coadding the MPC spectra obtained during all pointed observations of clusters

The entropy and energy of intergalactic gas in galaxy clusters

Studies of the X-ray surface brightness profiles of clusters, coupled with theoretical considerations, suggest that the breaking of self-similarity in the hot gas results from an ‘entropy floor’,

Statistical Properties of X-Ray Clusters: Analytic and Numerical Comparisons

We compare the results of Eulerian hydrodynamic simulations of cluster formation against virial scaling relations between four bulk quantities: the cluster mass, the dark matter velocity dispersion,

The LX-T Relation and Temperature Function for Nearby Clusters Revisited

The X-ray luminosity-temperature relation for nearby T ≃ 3.5-10 keV clusters is rederived using new ASCA temperatures and ROSAT luminosities. Both quantities are derived by directly excluding the

Mass estimates of X-ray clusters

We use cosmological gasdynamic simulations to investigate the accuracy of galaxy cluster mass estimates based on X-ray observations. The experiments follow the formation of clusters in different

An X-Ray Size-Temperature Relation for Galaxy Clusters: Observation and Simulation

We show that galaxy clusters conform to a tight relation between X-ray isophotal size RI and emission-weighted intracluster medium (ICM) temperature ⟨TX⟩. The best-fit relation for 41 members of an
