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…
