TL;DR: In this paper, the authors used Reflection Grating Spectrometer measurements of turbulent line broadening to place constraints on the propagation velocity of bulk turbulence within the intracluster medium of three clusters and an elliptical galaxy and showed that the upper limit on turbulent velocities when accounting for instrumental broadening is too low to propagate energy radially to the cooling radius of the clusters within the required cooling time.

TL;DR: In this paper, the authors present the results from a new optical/UV/X-ray monitoring campaign of the luminous Seyfert galaxy Fairall 9 using the Swift satellite.

TL;DR: In this article, a 36-ksec observation of the core of the Pleiades open cluster using ACIS-I on the Chandra X-ray Observatory has been conducted.

TL;DR: In this paper, a review of relativistic iron line studies for both accreting stellar mass black holes (i.e., GBHCs), and supermassive black holes is presented, where differences between classes of AGN can be diagnosed using X-ray spectroscopy.

TL;DR: In this paper, the authors present an ASCA observation of the broad-line radio galaxy 3C 111 and claim a marginal detection of a broad iron Kα line which is well explained as being a fluorescent line originating from the central regions of a radiatively efficient accretion disc.
