Non-Thermal Pressure due to Gas Motions in the Intracluster Medium: Confronting XRISM/Resolve with TNG-Cluster Simulations
Erwin T. Lau, Naomi Ota, Daisuke Nagai
Intracluster medium (ICM) gas motions probe cluster assembly, feedback, and non-thermal pressure support, but recent XRISM observations reveal velocity dispersions and non-thermal…
The Role of Penetrating Gas Streams in Setting the Dynamical State of Galaxy Clusters
E. Zinger, A. Dekel, Y. Birnboim +2
We utilize cosmological simulations of 16 galaxy clusters at redshifts \zeq{0} and \zeq{0.6} to study the effect of inflowing streams on the properties of the X-ray emitting intrac…
Analytical model for non-thermal pressure in galaxy clusters - III. Removing the hydrostatic mass bias
Xun Shi, Eiichiro Komatsu, Daisuke Nagai +1
Non-thermal pressure in galaxy clusters leads to underestimation of the mass of galaxy clusters based on hydrostatic equilibrium with thermal gas pressure. This occurs even for dyn…
Analytical model for non-thermal pressure in galaxy clusters
Xun Shi, Eiichiro Komatsu
Non-thermal pressure in the intracluster gas has been found ubiquitously in numerical simulations, and observed indirectly. In this paper we develop an analytical model for intracl…
Quantifying properties of ICM inhomogeneities
I. Zhuravleva, E. Churazov, A. Kravtsov +3
We present a new method to identify and characterize the structure of the intracluster medium (ICM) in simulated galaxy clusters. The method uses the median of gas properties, such…
Effect of Helium Sedimentation on X-ray Measurements of Galaxy Clusters
Fang Peng, Daisuke Nagai
The uniformity of the helium-to-hydrogen abundance ratio in X-ray emitting intracluster medium (ICM) is one of the commonly adopted assumptions in X-ray analyses of galaxy clusters…
"The Perfect Slope": A new robust low-scatter X-ray mass indicator for clusters of galaxies
Alexey Vikhlinin, Andrey V. Kravtsov, Daisuke Nagai
This presentation is a Moriond version of our recent paper (Kravtsov, Vikhlinin & Nagai astro-ph/0603205) where we discussed X-ray proxies for the total cluster mass, including the…
A New Robust Low-Scatter X-ray Mass Indicator for Clusters of Galaxies
Andrey V. Kravtsov, Alexey Vikhlinin, Daisuke Nagai
We present comparison of X-ray proxies for the total cluster mass, including the spectral temperature (Tx), gas mass measured within r500 (Mg), and the new proxy, Yx, which is a si…
