The Hot and Energetic Universe: A White Paper presenting the science theme motivating the Athena+ mission
This White Paper, submitted to the recent ESA call for science themes to define its future large missions, advocates the need for a transformational leap in our understanding of two key questions in…

Azimuthally Resolved X-Ray Spectroscopy to the Edge of the Perseus Cluster
We present the results from extensive, new observations of the Perseus Cluster of galaxies, obtained as a Suzaku Key Project. The 85 pointings analyzed span eight azimuthal directions out to 2…

Turbulent heating in galaxy clusters brightest in X-rays
TLDR
It is found that turbulent heating is sufficient to offset radiative cooling and indeed appears to balance it locally at each radius—it may be the key element in resolving the gas cooling problem in cluster cores and, more universally, in the atmospheres of X-ray-emitting, gas-rich systems on scales from galaxy clusters to groups and elliptical galaxies.

Quantifying properties of ICM inhomogeneities
We present a new method to identify and characterize the structure of the intracluster medium (ICM) in simulated galaxy clusters. The method uses the median of gas properties, such as density and…

A Uniform Contribution of Core-Collapse and Type Ia Supernovae to the Chemical Enrichment Pattern in the Outskirts of the Virgo Cluster
We present the first measurements of the abundances of $\alpha$-elements (Mg, Si, and S) extending out to beyond the virial radius of a cluster of galaxies. Our results, based on Suzaku Key Project…

Constraints on turbulent pressure in the X‐ray haloes of giant elliptical galaxies from resonant scattering
The dense cores of X-ray emitting gaseous halos of large elliptical galaxies with temperatures kT . 0.8 keV show two prominent Fexvii emission features, which provide a sensitive diagnostic tool to…

X-ray surface brightness and gas density fluctuations in the Coma cluster
X-ray surface brightness fluctuations in the core (650 × 650 kpc) region of the Coma cluster observed with XMM-Newton and Chandra are analyzed using a 2D power spectrum approach. The resulting 2D…

Constraints on turbulent pressure in the X-ray halos of giant elliptical galaxies from resonant scattering
Abstract The dense cores of X-ray emitting gaseous halos of large elliptical galaxies with temperatures below about 0.8 keV show two prominent Fe XVII emission features, which provide a sensitive…

Steepening mass profiles, dark matter and environment of X-ray bright elliptical galaxies
We use a new non-parametric Bayesian approach to obtain the most probable mass distributions and circular velocity curves along with their confidence ranges, given deprojected density and temperature…

Hitomi Constraints on the 3.5 keV Line in the Perseus Galaxy Cluster
High-resolution X-ray spectroscopy with Hitomi was expected to resolve the origin of the faint unidentified $E\approx 3.5\,\mathrm{keV}$ emission line reported in several low-resolution studies of…
