Gas Stripping of Dwarf Galaxies in Clusters of Galaxies [PDF]

, 2000
Many clusters of galaxies contain an appreciable amount of hot gas, the intracluster medium. As a consequence, gas will be stripped from galaxies that move through the inter cluster medium, if the ram pressure exceeds the internal gravitational force. We

Detrending Changes the Temporal Dynamics of a Semantic Fluency Task

Frontiers in Aging Neuroscience, 2016
Objective: To study the dynamics of clustering semantic fluency responses and switching between clusters. Methods: We conducted a cross-sectional study of participants (N=60) in a study of patient reported outcomes who were given the Saint Louis ...

The X-Ray Intracluster Medium [PDF]

Symposium - International Astronomical Union, 1996
Clusters of galaxies are the largest aggregates of matter that have decoupled from the universal expansion and have approximately evolved to a proper dynamical equilibrium configuration. While in the optical they are just observed as dense concentrations of galaxies, they are seen in X-rays as continuously connected entities through the emission of the

Nonthermal support for the outer intracluster medium [PDF]

Astronomy & Astrophysics, 2010
We submit that non thermalized support for the outer intracluster medium in relaxed galaxy clusters is provided by turbulence, driven by inflows of intergalactic gas across the virial accretion shocks. We expect this component to increase briskly during the cluster development for z<1/2, due to three factors.

Dust in Clusters of Galaxies

Universe, 2022
The presence of dust in the intracluster medium (ICM) has been a long-standing problem that is still awaiting elucidation. Direct observational diagnostics are rather challenging (though not impossible) either because of a sparse distribution of dust in ...

Rescuing the intracluster medium of NGC 5813

, 2016
We use recent X-ray observations of the intracluster medium (ICM) of the galaxy group NGC 5813 to confront theoretical studies of ICM thermal evolution with the newly derived ICM properties. We argue that the ICM of the cooling flow galaxy group NGC 5813

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.

Heating of the intracluster medium

The Astrophysical Journal, 1990
The gravitational interaction of the system of galaxies and the ICM are treated by fluctuation theory. Fluctuation theory seems to be more adequate to describe the gravitational interaction than local theories used up to now, because gravitation is a long-range force.

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.
