Measuring bulk flows of the intracluster medium in the Perseus and Coma galaxy clusters using XMM-Newton
J. S. Sanders, K. Dennerl, H. R. Russell +7
We demonstrate a novel technique for calibrating the energy scale of the XMM EPIC-pn detector, which allows us to measure bulk flows in the intracluster medium (ICM) of the Perseus…
7.1 keV sterile neutrino dark matter constraints from a deep Chandra X-ray observation of the Galactic bulge Limiting Window
F. Hofmann, C. Wegg
Recently an unidentified emission line at 3.55 keV has been detected in X-ray spectra of clusters of galaxies. The line has been discussed as a possible decay signature of 7.1 keV…
The Galactic Centre Chimney
G. Ponti, F. Hofmann, E. Churazov +6
Evidence has increasingly mounted in recent decades that outflows of matter and energy from the central parsecs of our Galaxy have shaped the observed structure of the Milky Way on…
Synthetic simulations of the extragalactic sky seen by eROSITA. I. Pre-launch selection functions from Monte-Carlo simulations
N. Clerc, M. E. Ramos-Ceja, J. Ridl +15
Studies of galaxy clusters provide stringent constraints on models of structure formation. Provided that selection effects are under control, large X-ray surveys are well suited to…
New transient Galactic bulge intermediate polar candidate XMMU J175035.2-293557
F. Hofmann, G. Ponti, F. Haberl +1
For the past decades a rare subclass of cataclysmic variables (CV), with magnetized white dwarfs (WD) as accretors has been studied and called intermediate polars (IP). They have b…
eROSITA cluster cosmology forecasts: cluster temperature substructure bias
F. Hofmann, J. S. Sanders, N. Clerc +6
The eROSITA mission will provide the largest sample of galaxy clusters detected in X-ray to date (one hundred thousand expected). This sample will be used to constrain cosmological…
CHEERS: The chemical evolution RGS sample
J. de Plaa, J. S. Kaastra, N. Werner +17
The chemical yields of supernovae and the metal enrichment of the hot intra-cluster medium (ICM) are not well understood. This paper introduces the CHEmical Enrichment RGS Sample (…
7.1 keV sterile neutrino constraints from X-ray observations of 33 clusters of galaxies with Chandra ACIS
F. Hofmann, J. S. Sanders, K. Nandra +2
Recently an unidentified emission line at 3.55 keV has been detected in X-ray spectra of clusters of galaxies. The line has been discussed as a possible decay signature of 7.1 keV…
A White Paper on keV Sterile Neutrino Dark Matter
R. Adhikari, M. Agostini, N. Anh Ky +133
We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting views and insights from all disciplines involved - cosmology, astrophysics, nuclear, and par…
Thermodynamic perturbations in the X-ray halo of 33 clusters of galaxies observed with Chandra ACIS
F. Hofmann, J. S. Sanders, K. Nandra +2
In high-resolution X-ray observations of the hot plasma in clusters of galaxies significant structures caused by AGN feedback, mergers, and turbulence can be detected. Many cluster…
Feedback, scatter and structure in the core of the PKS 0745-191 galaxy cluster
J. S. Sanders, A. C. Fabian, J. Hlavacek-Larrondo +5
We present Chandra X-ray Observatory observations of the core of the galaxy cluster PKS 0745-191. Its centre shows X-ray cavities caused by AGN feedback and cold fronts with an ass…
X-ray monitoring of classical novae in the central region of M31. III. Autumn and winter 2009/10, 2010/11 and 2011/12
M. Henze, W. Pietsch, F. Haberl +7
[Abridged] Classical novae (CNe) represent the major class of supersoft X-ray sources (SSSs) in the central region of our neighbouring galaxy M31. We performed a dedicated monitori…
X-ray source variability study of the M 31 central field using Chandra HRC-I
F. Hofmann, W. Pietsch, M. Henze +5
[Abridged] The central field of the Andromeda galaxy (M 31) has been monitored, using the Chandra HRC-I detector (about 0.1-10 keV energy range) from 2006 to 2012 with the main aim…
Supersoft X-rays reveal a classical nova in the M 31 globular cluster Bol 126
M. Henze, W. Pietsch, F. Haberl +17
[Abridged] Classical novae (CNe) represent the main class of supersoft X-ray sources (SSSs) in the central region of our neighbouring galaxy M 31. Only three confirmed novae and th…
