Mass Accretion and its Effects on the Self-Similarity of Gas Profiles in the Outskirts of Galaxy Clusters
Erwin T. Lau, Daisuke Nagai, Camille Avestruz +2
Galaxy clusters exhibit remarkable self-similar behavior which allows us to establish simple scaling relationships between observable quantities and cluster masses, making galaxy c…
Non-Equilibrium Electrons in the Outskirts of Galaxy Clusters
Camille Avestruz, Daisuke Nagai, Erwin T. Lau +1
The analysis of X-ray and Sunyaev-Zeldovich measurements of the intracluster medium (ICM) assumes that electrons are in thermal equilibrium with ions in the plasma. However, electr…
Temperature Structure of the Intra-Cluster Medium from SPH and AMR simulations
Elena Rasia, Erwin T. Lau, Stefano Borgani +8
Analyses of cosmological hydrodynamic simulations of galaxy clusters suggest that X-ray masses can be underestimated by 10% to 30%. The largest bias originates by both violation of…
The relation between gas density and velocity power spectra in galaxy clusters: qualitative treatment and cosmological simulations
I. Zhuravleva, E. Churazov, A. A. Schekochihin +6
We address the problem of evaluating the power spectrum of the velocity field of the ICM using only information on the plasma density fluctuations, which can be measured today by C…
The relation between gas density and velocity power spectra in galaxy clusters: high-resolution hydrodynamic simulations and the role of conduction
M. Gaspari, E. Churazov, D. Nagai +2
Exploring the ICM power spectrum can help us to probe the physics of galaxy clusters. Using high-resolution 3D plasma simulations, we study the statistics of the velocity field and…
Hydrodynamic Simulation of Non-thermal Pressure Profiles of Galaxy Clusters
Kaylea Nelson, Erwin T. Lau, Daisuke Nagai
Cosmological constraints from X-ray and microwave observations of galaxy clusters are subjected to systematic uncertainties. Non-thermal pressure support due to internal gas motion…
