Distribution and Evolution of Metals in the Magneticum Simulations

Galaxies, 2017
Metals are ideal tracers of the baryonic cycle within halos. Their composition is a fossil record connecting the evolution of the various stellar components of galaxies to the interaction with the environment by in- and out-flows.

SZ–X-Ray Surface Brightness Fluctuations in the SPT-XMM Clusters

The Astrophysical Journal
The hot plasma in galaxy clusters, the intracluster medium, is expected to be shaped by subsonic turbulent motions, which are key for heating, cooling, and transport mechanisms.

GeV Gamma-ray Flux Upper Limits from Clusters of Galaxies [PDF]

, 2010
The detection of diffuse radio emission associated with clusters of galaxies indicates populations of relativistic leptons infusing the intracluster medium.

The metallicity of the intracluster medium over cosmic time: further evidence for early enrichment [PDF]

, 2017
We use Chandra X-ray data to measure the metallicity of the intracluster medium (ICM) in 245 massive galaxy clusters selected from X-ray and Sunyaev-Zel'dovich (SZ) effect surveys, spanning redshifts 0 < z < 1.2.

Multiscale analysis of turbulence evolution in the density-stratified intracluster medium [PDF]

Monthly notices of the Royal Astronomical Society, 2018
The diffuse hot medium inside clusters of galaxies typically exhibits turbulent motions whose amplitude increases with radius, as revealed by cosmological hydrodynamical simulations. However, its physical origin remains unclear. It could either be due to

IDLB: An SDN‐Based Load‐Balancing Routing Protocol for Autonomous Satellite Constellation Networks

International Journal of Satellite Communications and Networking, Volume 44, Issue 2, Page 109-127, March/April 2026.
ABSTRACT Routing in satellite constellation networks with intersatellite links has become an important aspect to enable broadband Internet access and to integrate into terrestrial networks. However, their dynamic characteristics and large physical size require specifically tailored solutions.

Unveiling the Sources of X-Ray Luminosity in DESI Galaxy Groups: Insights from the SRG/eROSITA All-sky Survey

The Astrophysical Journal
We use the first eROSITA all-sky survey to investigate the contributions of active galactic nuclei (AGN) and extended gas to the total X-ray luminosity ( L _X ) of galaxy groups with different halo masses ( M _h ) at different redshifts.

Deep Synoptic Array Science: Two Fast Radio Burst Sources in Massive Galaxy Clusters

The Astrophysical Journal Letters, 2023
The hot gas that constitutes the intracluster medium (ICM) has been studied at X-ray and millimeter/submillimeter wavelengths (Sunyaev–Zel’dovich effect) for decades.

The ‘FRIENDS for Life’ emotional health programme: Differential impact for those at risk

British Journal of Educational Psychology, Volume 96, Issue 1, Page 152-171, March 2026.
Abstract Background Evidence suggests that FRIENDS, a universal cognitive behavioural programme for schools, can improve children's emotional health, yet debate persists regarding its efficacy with respect to prevention versus treatment, particularly for children at risk of anxiety disorders.
