Abundance and temperature distributions in the hot intra-cluster gas of Abell 4059
François Mernier, Jelle de Plaa, Lorenzo Lovisari +5
Using the EPIC and RGS data from a deep (~200 ks) XMM-Newton observation, we investigate the temperature structure (kT and sigma_T ) and the abundances of 9 elements (O, Ne, Mg, Si…
The radio relic in Abell 2256: overall spectrum and implications for electron acceleration
M. Trasatti, H. Akamatsu, L. Lovisari +5
The galaxy cluster Abell 2256 hosts one of the most intriguing examples in the class of radio relics. It has been found that this radio relic has a rather flat integrated spectrum…
A metal-rich elongated structure in the core of the group NGC4325
T. F Laganá, L. Lovisari, L. Martins +3
We used X-ray 2D spectrally resolved maps to resolve structure in temperature and metal abundance. To perform stellar population analysis we applied the spectral fitting technique…
Scaling Properties of a Complete X-ray Selected Galaxy Group Sample
Lorenzo Lovisari, Thomas Reiprich, Gerrit Schellenberger
Upcoming X-ray surveys like eROSITA require precise calibration between X-ray observables and mass down to the low mass regime to set tight constraints on the fundamental cosmologi…
Extending the relation from clusters to groups-Impact of cool core nature, AGN feedback, and selection effects
V. Bharadwaj, T. H. Reiprich, L. Lovisari +1
We aim to investigate the bolometric relation for galaxy groups, and study the impact of gas cooling, feedback from supermassive black holes, and selection effec…
Metal distribution in the ICM - a comprehensive numerical study of twelve galaxy clusters
Harald Höller, Josef Stöckl, Andrew Benson +4
We present a simulation setup for studying the dynamical and chemical evolution of the intracluster medium (ICM) and analyze a sample of 12 galaxy clusters that are diverse both ki…
Constraining galaxy cluster temperatures and redshifts with eROSITA survey data
Katharina Borm, Thomas H. Reiprich, Irshad Mohammed +1
The nature of dark energy is imprinted in the large-scale structure of the Universe and thus in the mass and redshift distribution of galaxy clusters. The upcoming eROSITA mission…
XMM-Newton and Chandra Cross Calibration Using HIFLUGCS Galaxy Clusters: Systematic Temperature Differences and Cosmological Impact
G. Schellenberger, T. H. Reiprich, L. Lovisari +2
Cosmological constraints from clusters rely on accurate gravitational mass estimates, which strongly depend on cluster gas temperature measurements. Therefore, systematic calibrati…
