Enrichment of the Hot Intracluster Medium: Observations
Yamaguchi, H.; Simionescu, A.; Kaastra, J. S. +7 more
Four decades ago, the firm detection of an Fe-K emission feature in the X-ray spectrum of the Perseus cluster revealed the presence of iron in its hot intracluster medium (ICM). With more advanced missions successfully launched over the last 20 years, this discovery has been extended to many other metals and to the hot atmospheres of many other ga…
Measuring Black Hole Spin Using X-Ray Reflection Spectroscopy
Reynolds, Christopher S.
I review the current status of X-ray reflection (a.k.a. broad iron line) based black hole spin measurements. This is a powerful technique that allows us to measure robust black hole spins across the mass range, from the stellar-mass black holes in X-ray binaries to the supermassive black holes in active galactic nuclei. After describing the basic …
The Solar Wind Charge-eXchange Contribution to the Local Soft X-ray Background. Model to Data Comparison in the 0.1-1.0 keV Band
Lallement, Rosine; Koutroumpa, Dimitra; Kharchenko, Vasili +1 more
The major sources of the Soft X-ray Background (SXRB), besides distinct structures as supernovae and superbubbles (e.g. Loop I), are: (i) an absorbed extragalactic emission following a power law, (ii) an absorbed thermal component (∼2×106 K) from the galactic disk and halo, (iii) an unabsorbed thermal component, supposedly at 106
Soft X-Ray and Extreme Ultraviolet Excess Emission from Clusters of Galaxies
Kaastra, J. S.; Durret, F.; Werner, N. +2 more
An excess over the extrapolation to the extreme ultraviolet and soft X-ray ranges of the thermal emission from the hot intracluster medium has been detected in a number of clusters of galaxies. We briefly present each of the satellites (EUVE, ROSAT PSPC and BeppoSAX, and presently XMM-Newton, Chandra and Suzaku) and their corresponding instrumenta…
