We present preliminary results of a XMM-Newton 50 ks observation of the Perseus Cluster that provides an unprecedented view of the central 0.5 Mpc region. The projected gas temperature declines smoothly by a factor of 2 from a maximum value of ~ 7 keV in the outer regions to just above 3 keV at the cluster center. Over this same range, the heavy-element abundance rises slowly from 0.4 to 0.5 solar as the radius decreases from 14' to 5', and then it rises to a peak of almost 0.7 solar at 1.′25… 

XMM-Newton Observation of IC 310 in the Outer Region of the Perseus Cluster of Galaxies

We present results from an XMM-Newton observation of the head-tail radio galaxy IC 310 located in the southwest region of the Perseus cluster. The spectrum is well fitted by an absorbed power-law

Detailed XMM-Newton Observation of the Cluster of Galaxies Abell 1060

We present results from the XMM-Newton observation of the non-cooling flow cluster A1060. Large effective area of XMM-Newton enables us to investigate the nature of this cluster in unprecedented

XMM—Newton observations of the Perseus cluster — II. Evidence for gas motions in the core

The 5–9 keV spectrum of the inner ∼100 kpc of the Perseus cluster measured by XMM–Newton can be well described by an optically thin plasma emission model as predicted by the apec code, without any

XMM-Newton Observations of A133: A Weak Shock Passing through the Cool Core

We use XMM-Newton observations of the cluster of galaxies A133 to study the X-ray spectrum of the intracluster medium (ICM). We find a cold front to the southeast of the cluster core. From the

A Chandra observation of the disturbed cluster core of Abell 2204

We present results from an observation of the luminous cluster of galaxies Abell 2204 using the Chandra X-ray Observatory. We show the core of the cluster has a complex morphological structure, made

XMM-Newton Study of A3562 and Its Immediate Shapley Environs

Using a mosaic of six XMM-Newton observations, we study the hydrodynamic state of A3562, a cluster in the center of the Shapley supercluster. The X-ray image reveals a sharp surface brightness

A deep XMM–Newton study of the hot gaseous halo around NGC 1961

We examine 11 XMM-Newton observations of the giant spiral galaxy NGC 1961, allowing us to study the hot gaseous halo of a spiral galaxy in unprecedented detail. We perform a spatial and a spectral

NuStar View of the Central Region of the Perseus Cluster

Located at the center of the Perseus cluster, 3C 84 is an extremely bright and nearby radio galaxy. Because of the strong diffuse thermal emission from the cluster in X-rays, the detailed properties


We present results from a 140 ks Chandra/ACIS-S observation of the hot gas around the canonical FR I radio galaxy 3C 449. An earlier, shorter 30 ks Chandra observation of the group gas showed an

Non-thermal X-rays, a high-abundance ridge and fossil bubbles in the core of the Perseus cluster of galaxies

Using a deep Chandra observation of the Perseus cluster of galaxies, we find a high-abundance shell 250 arcsec (93 kpc) from the central nucleus. This ridge lies at the edge of the Perseus radio



Evidence for Merging in the Centaurus Cluster

We present a two-dimensional map of the gas temperature distribution in the Centaurus cluster, based on Advanced Satellite for Cosmology and Astrophysics (ASCA) observations derived using a novel

A Moving Cold Front in the Intergalactic Medium of A3667

We present results from a Chandra observation of the central region of the galaxy cluster A3667 with emphasis on the prominent sharp X-ray brightness edge spanning 0.5 Mpc near the cluster core. Our

ROSAT PSPC observations of the outer regions of the Perseus cluster of galaxies

We present an analysis of four off-axis ROSAT Position Sensitive Proportional Counter (PSPC) observations of the Perseus cluster of galaxies (Abell 426). We detect the surface brightness profile to a

Chandra temperature and metallicity maps of the Perseus cluster core

We present temperature and metallicity maps of the Perseus cluster core obtained with the Chandra X-ray Observatory. We find an overall temperature rise from ∼3.0 keV in the core to ∼5.5 keV at 120

Chandra imaging of the X-ray core of Abell 1795

We report the discovery of a 40 arcsec long X-ray filament in th e core of the cluster of galaxies A 1795. The feature coincides with an H�+NII filament found by Cowie et al in the early 1980s and


The NGC 5044 group of galaxies was observed by the ROSAT Position Sensitive Proportional Counter (PSPC) for 30 ks during its reduced pointed phase (1991 July). Due to the relatively cool gas

Temperature Structure in Abell 1367

We study the temperature structure of the rich cluster of galaxies Abell 1367 using two independent methods of correcting for the ASCA point-spread function. The results of the two methods are in

On the Nature of the NGC 1275 System

Subarcsecond images, taken in B, R, and Hα filters, and area spectroscopy obtained with the WIYN 3.5 m telescope provide the basis for an investigation of the unusual structures in the stellar body

Einstein Observatory Images of Clusters of Galaxies

We present the X-ray characteristics of a sample of 368 clusters of galaxies with redshifts less than 0.2 observed with the Einstein Imaging Proportional Counter. For each cluster, we measure the

Nonhydrostatic Gas in the Core of the Relaxed Galaxy Cluster A1795

Chandra data on A1795 reveal a mild edge-shaped discontinuity in the gas density and temperature in the southern sector of the cluster at r = 60 h-1 kpc. The gas inside the edge is 1.3-1.5 times
