Cosmological simulations of the intracluster medium [PDF]
Monthly Notices of the Royal Astronomical Society, 2004 We investigate the properties of the intracluster medium (ICM) that forms within N-body/hydrodynamical simulations of galaxy clusters in a \LambdaCDM cosmology. When radiative cooling and a simple model for galactic feedback are included, our clusters have X-ray luminosities and temperatures in good agreement with observed systems, demonstrating the ...

Gravity-selected Cluster Samples: A New Take on the Compton-y–Mass Relation
The Astrophysical JournalWe investigate the scaling relation between the Compton- y parameter and mass in a gravity-selected sample of galaxy clusters, selected based on their gravitational lensing effects on background galaxies. Unlike intracluster medium (ICM)−selected samples,

EE‐FGO: Energy‐Efficient Fuzzy Grey Wolf Optimization for Cluster Head Selection in WSN
Journal of Electrical and Computer Engineering, Volume 2026, Issue 1, 2026.A crucial component of the Internet of Things (IoT) is the wireless sensor network (WSN), which comprises numerous sensor nodes detecting various atmospheric variations such as temperature, pressure and humidity. These sensor nodes rely on internal batteries to power their sensors and communicate data with other nodes within the network.

MHD turbulence in the intracluster medium [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractIn this work we discuss the turbulent evolution of structures in the intracluster medium based on the two fluid approximations: MHD and collisionless plasma under Chew Goldberger Low (CGL) closure. Turbulence excited by galactic motions and gas inflow in intracluster medium will develop in very different ways considering the two fluid ...

Advanced Materials, Volume 37, Issue 48, December 3, 2025.This review examines the critical role of neighboring active motifs in heterogeneous catalysts, emphasizing how their synergistic cooperativity can be rationally designed to modulate catalytic properties. The discussion centers on the modulation of electronic and geometric structures, categorizing the catalytic systems into metal‐acid (Brønsted/Lewis ...

Chemical Evolution Of Galaxies And Intracluster Medium [PDF]
, 2004 In this series of lectures I discuss the basic principles and the modelling of the chemical evolution of galaxies. In particular, I present models for the chemical evolution of the Milky Way galaxy and compare them with the available observational data.

Merger-driven Turbulence and Coherent Transport in the Intracluster Medium
The Astrophysical JournalThe distribution of metals and temperature in the intracluster medium (ICM) provides key insights into galaxy cluster evolution, revealing information about chemical enrichment and heating and cooling processes, respectively.

Galaxy Cluster Outskirts from the Thermal SZ and Non-Thermal Synchrotron Link
Galaxies, 2016 Galaxy cluster merger shocks are the main agent for the thermalization of the intracluster medium and the energization of cosmic ray particles in it. Shock propagation changes the state of the tenuous intracluster plasma, and the corresponding signal ...
