Serendipitous discovery of an extended X-ray jet without a radio counterpart in a high-redshift quasar
A. Simionescu, Ł. Stawarz, Y. Ichinohe +6
A recent Chandra observation of the nearby galaxy cluster Abell 585 has led to the discovery of an extended X-ray jet associated with the high-redshift background quasar B3 0727+40…
Suzaku observations of a shock front tracing the western edge of the giant radio halo in the Coma Cluster
Y. Uchida, A. Simionescu, T. Takahashi +5
We present the results of new Suzaku observations of the Coma Cluster, the X-ray brightest, nearby, merging system hosting a well studied, typical giant radio halo. It has been pre…
A Uniform Contribution of Core-Collapse and Type Ia Supernovae to the Chemical Enrichment Pattern in the Outskirts of the Virgo Cluster
A. Simionescu, N. Werner, O. Urban +3
We present the first measurements of the abundances of -elements (Mg, Si, and S) extending out to beyond the virial radius of a cluster of galaxies. Our results, based on Suzaku…
A Very Deep Chandra Observation of the Galaxy Group NGC 5813: AGN Shocks, Feedback, and Outburst History
S. W. Randall, P. E. J. Nulsen, C. Jones +11
We present results from a very deep (650 ks) Chandra X-ray observation of the galaxy group NGC~5813, the deepest Chandra observation of a galaxy group to date. Earlier observations…
Gas Density Fluctuations in the Perseus Cluster: Clumping Factor and Velocity Power Spectrum
I. Zhuravleva, E. Churazov, P. Arevalo +9
X-ray surface brightness fluctuations in the core of the Perseus Cluster are analyzed, using deep observations with the Chandra observatory. The amplitude of gas density fluctuatio…
Collisional excitation of [C II], [O I] and CO in Massive Galaxies
R. E. A. Canning, G. J. Ferland, A. C. Fabian +5
Many massive galaxies at the centres of relaxed galaxy clusters and groups have vast reservoirs of cool (~10,000 K) and cold (~100 K) gas. In many low redshift brightest group and…
