Statistics of Gas Density, Velocity, and Magnetic Fields in Cool-core Galaxy Clusters

open access: yesThe Astrophysical Journal
Understanding turbulence within the intracluster medium of galaxy clusters is pivotal for comprehending their evolution and dynamics. Employing 3D magnetohydrodynamic simulations of galaxy cluster mergers, we examine the statistical properties of gas ...

Detection of Extragalactic Magnetic Fields through analysis of Photon Arrival Directions

open access: yes, 2018
The existence of large-scale extragalactic magnetic fields (EGMFs) has been a subject of some debate over the last few decades. Recent work done on the analysis of cascade photons from high energy sources like Blazars (Tashiro and Vachaspati, 2013; Chen ...

A Simple Model of the Radio–Infrared Correlation Depending on Gas Surface Density and Redshift

open access: yesThe Astrophysical Journal
We introduce a simple parametric model of the radio–infrared correlation (i.e., the ratio between the IR luminosity and the 1.4 GHz radio luminosity, q _IR ) by considering the energy loss rate of high-energy cosmic-ray (CR) electrons governed by ...

Gravitational lens systems to probe extragalactic magnetic fields [PDF]

open access: yes, 2007
The faraday rotation measurements of multiply-imaged gravitational lens systems can be effectively used to probe the existence of large-scale ordered magnetic fields in lensing galaxies and galaxy clusters. The available sample of lens systems appears to

Observing Interstellar and Intergalactic Magnetic Fields

open access: yes, 2017
Observational results of interstellar and intergalactic magnetic fields are reviewed, including the fields in supernova remnants and loops, interstellar filaments and clouds, Hii regions and bubbles, the Milky Way and nearby galaxies, galaxy clusters ...
