Systematic comparison of photoionised plasma codes with application to spectroscopic studies of AGN in X-rays
M. Mehdipour, J. S. Kaastra, T. Kallman
Atomic data and plasma models play a crucial role in the diagnosis and interpretation of astrophysical spectra, thus influencing our understanding of the universe. In this investig…
The complex circumnuclear environment of the broad-line radio galaxy 3C 390.3 revealed by Chandra HETG
F. Tombesi, J. N. Reeves, T. Kallman +6
We present the first high spectral resolution X-ray observation of the broad-line radio galaxy 3C 390.3 obtained with the high energy transmission grating (HETG) spectrometer on bo…
The Quiescent Intracluster Medium in the Core of the Perseus Cluster
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +213
Clusters of galaxies are the most massive gravitationally-bound objects in the Universe and are still forming. They are thus important probes of cosmological parameters and a host…
Hitomi constraints on the 3.5 keV line in the Perseus galaxy cluster
Hitomi Collaboration, Felix A. Aharonian, Hiroki Akamatsu +215
High-resolution X-ray spectroscopy with Hitomi was expected to resolve the origin of the faint unidentified E=3.5 keV emission line reported in several low-resolution studies of va…
On the detectability of CO molecules in the Interstellar Medium via X-ray spectroscopy
Katerine Joachimi, Efraín Gatuzz, Javier A. García +1
We present a study of the detectability of CO molecules in the Galactic interstellar medium using high-resolution X-ray spectra obtained with the XMM-Newton Reflection Grating Spec…
Fe K Profiles from Simulations of Accreting Black Holes
Brooks E. Kinch, Jeremy D. Schnittman, Timothy R. Kallman +1
We present first results from a new technique for the prediction of Fe K profiles directly from general relativistic magnetohydrodynamic (GRMHD) simulations. Data from a GRMHD s…
