A holistic view on ram pressure stripping in the Virgo cluster - The first complete model-based time sequence

, 2009
Based on a comparison of dynamical models with observations of the interstellar gas in 6 Virgo cluster spiral galaxies a first complete ram pressure stripping time sequence has been established.

Resolved magnetic dynamo action in the simulated intracluster medium [PDF]

, 2017
Faraday rotation and synchrotron emission from extragalactic radio sources give evidence for the presence of magnetic fields extending over ˜ Mpc scales. However, the origin of these fields remains elusive.

Observational Predictions for the Survival of Atomic Hydrogen in Simulated Fornax-like Galaxy Clusters

The Astrophysical Journal
The presence of dense, neutral hydrogen clouds in the hot, diffuse intragroup and intracluster (IC) medium is an important clue to the physical processes controlling the survival of cold gas and sheds light on cosmological baryon flows in massive halos ...

Cosmic-Ray Feedback Heating of the Intracluster Medium [PDF]

, 2017
Active galactic nuclei (AGNs) play a central role in solving the decades-old cooling-flow problem. Although there is consensus that AGNs provide the energy to prevent catastrophically large star formation, one major problem remains: How is the AGN energy

Surface Brightness Fluctuations in Two SPT Clusters: A Pilot Study

The Astrophysical Journal
Studies of surface brightness fluctuations in the intracluster medium present an indirect probe of turbulent properties such as the turbulent velocities, injection scales, and the slope of the power spectrum of fluctuations toward smaller scales.

HOW AGN JETS HEAT THE INTRACLUSTER MEDIUM—INSIGHTS FROM HYDRODYNAMIC SIMULATIONS [PDF]

, 2016
Feedback from active galactic nuclei (AGNs) is believed to prevent catastrophic cooling in galaxy clusters. However, how the feedback energy is transformed into heat, and how the AGN jets heat the intracluster medium (ICM) isotropically, still remain ...

Effect of a Spiritual Care Program on Treatment Adherence and Sleep Quality in Hemodialysis Patients: A Cluster‐Randomized Clinical Trial

Health Science Reports, Volume 8, Issue 12, December 2025.
ABSTRACT Background and Aims Declining sleep quality is common among hemodialysis patients, adversely affecting their quality of life and treatment adherence. Improving sleep is a nursing priority, and targeted interventions might be beneficial. This study aimed to evaluate the effect of a spiritual care program on treatment adherence and sleep quality

Buoyancy Instabilities in a Weakly Collisional Intracluster Medium

, 2012
The intracluster medium of galaxy clusters is a weakly collisional, high-beta plasma in which the transport of heat and momentum occurs primarily along magnetic-field lines.

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.

The deep latent position topic model for clustering and representation of networks with textual edges

Scandinavian Journal of Statistics, Volume 52, Issue 4, Page 1975-2013, December 2025.
Abstract Numerical interactions leading to users sharing textual content published by others are naturally represented by a network where the individuals are associated with the nodes and the exchanged texts with the edges. To understand those heterogeneous and complex data structures, clustering nodes into homogeneous groups as well as rendering a ...
