Chandra observations of RXJ1347.5-1145: the distribution of mass in the most X-ray luminous galaxy cluster known
S. W. Allen, R. W. Schmidt, A. C. Fabian
We present Chandra observations of RXJ1347.5-1145, the most X-ray luminous cluster of galaxies known. We report the discovery of a region of relatively hot, bright X-ray emission,…
The Chandra High Energy Transmission Grating Spectrometer probes the dusty warm absorber in the Seyfert 1 galaxy MCG--6-30-15
J. C. Lee, C. R. Canizares, H. L. Marshall +4
The Chandra HETGS spectra of the Seyfert 1 galaxy MCG--6-30-15 show numerous narrow, unresolved (FWHM < 200 km/s) absorption lines from a wide range of ionization states of N, O, M…
Spatially-resolved X-ray spectroscopy of the core of the Centaurus cluster
J. S. Sanders, A. C. Fabian
We present Chandra data from a 31.7 ks observation of the Centaurus cluster, using the ACIS-S detector. Images of the X-ray emission show a plume-like feature at the centre of the…
Thunderclouds and accretion discs: a model for the spectral and temporal variability of Seyfert 1 galaxies
A. Merloni, A. C. Fabian
X-ray observations of Seyfert 1 galaxies offer the unique possibility of observing spectral variability on timescales comparable to the dynamical time of the inner accretion flow.…
Multi-wavelength observations of serendipitous Chandra sources
P. Gandhi, C. S. Crawford, A. C. Fabian +4
We describe progress in a programme to study a sample of sources typical of those which contribute a large fraction of the hard X-ray background. The sources are selected from the…
Deep Sky Objects and the X-ray Background
A. C. Fabian
Deep observations of the X-ray Sky have now resolved most of the X-ray Background. Obscured active galaxies are a key component. The obscured objects which dominate at fluxes above…
