Building a cluster: shocks, cavities, and cooling filaments in the group-group merger NGC 6338
Ewan O'Sullivan, Gerrit Schellenberger, D. J. Burke +4
We present deep Chandra, XMM-Newton, Giant Metrewave Radio Telescope and Halpha observations of the group-group merger NGC 6338. X-ray imaging and spectral mapping show that as wel…
Projection effects in galaxy cluster samples: insights from X-ray redshifts
M. E. Ramos-Ceja, F. Pacaud, T. H. Reiprich +3
Up to now, the largest sample of galaxy clusters selected in X-rays comes from the ROSAT All-Sky Survey (RASS). Although there have been many interesting clusters discovered with t…
HICOSMO - Cosmology with a complete sample of galaxy clusters: II. Cosmological results
G. Schellenberger, T. H. Reiprich
The growth of structure in the Universe is tightly correlated with the cosmological parameters. Galaxy clusters as tracers of the large scale structure are the ideal objects to wit…
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…
Reconciling Planck cluster counts and cosmology? Chandra/XMM instrumental calibration and hydrostatic mass bias
Holger Israel, Gerrit Schellenberger, Jukka Nevalainen +2
The mass of galaxy clusters can be inferred from the temperature of their X-ray emitting gas, . Their masses may be underestimated if it is assumed that the gas is…
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…
