Journal ArticleDOI
pacerman — I. A new algorithm to calculate Faraday rotation maps
TL;DR: In this paper, the authors proposed PACERMAN (Polarization Angle CorrEcting Rotation Measure ANalysis) algorithm, which solves the nπ-ambiguity problem for a high signal-to-noise region "democratically" and uses this information to assist computations in adjacent low-sensor regions.
Journal ArticleDOI
The Outer Halos of Very Massive Galaxies: BCGs and their DSC in the Magneticum Simulations
TL;DR: In this paper, the authors investigate the buildup of the diffuse stellar component (DSC) around massive galaxies within group and cluster environments, and find that the DSC in almost all cases shows a clear separation from the brightest cluster galaxy (BCG) with regard to its dynamic state.
Journal ArticleDOI
QSO-galaxy correlations induced by weak lensing in arbitrary Friedmann-Lemaître cosmologies
Klaus Dolag,Matthias Bartelmann +1 more
TL;DR: In this paper, the angular cross-correlation function between background QSOs and ground galaxies induced by the weak lensing effect of large-scale structures is calculated for arbitrary Friedmann-Lemfeatre cosmologies.
Journal ArticleDOI
Scaling Relation in Two Situations of Extreme Mergers
Elena Rasia,Pasquale Mazzotta,Pasquale Mazzotta,August E. Evrard,Maxim Markevitch,Klaus Dolag,Massimo Meneghetti +6 more
TL;DR: In this paper, the authors extend previous studies of this apparent paradox using numerical simulations of two extreme merger cases, one is a high Mach number (above 2.5) satellite merger similar to the "bullet cluster" and the other is a merger of nearly equal-mass progenitors.
Journal ArticleDOI
Hydrodynamical simulations of galaxy clusters in dark energy cosmologies: I. general properties
Cristiano De Boni,Klaus Dolag,Stefano Ettori,Lauro Moscardini,Valeria Pettorino,Carlo Baccigalupi +5 more
TL;DR: In this article, the influence of dark energy on structure formation, within five different cosmological models, was investigated, namely, a concordance CDM model, two models with dynamical dark energy, viewed as a quintessence scalar field (using a RP and a SUGRA potential form) and two extended quintessensemble models (EQp and EQn) where the quadratic field interacts non-minimally with gravity (scalar-tensor theories).
