X-RAY STUDIES OF THE INTRACLUSTER MEDIUM IN CLUSTERS OF GALAXIES - CHARACTERIZING GALAXY CLUSTERS AS GIANT LABORATORIES [PDF]

open access: yesJournal of The Korean Astronomical Society, 2004
Galaxy clusters as the densest and most prominent regions within the large-scale structure can be used as well characterizable laboratories to study astrophysical processes on the largest scales. X-ray observations provide currently the best way to determine the physical properties of galaxy clusters and the environmental parameters that describe them ...

CHARACTERIZATION OF INTRACLUSTER MEDIUM TEMPERATURE DISTRIBUTIONS OF 62 GALAXY CLUSTERS WITH XMM-NEWTON [PDF]

open access: yesThe Astrophysical Journal, 2013
We measure the intracluster medium (ICM) temperature distributions for 62 galaxy clusters in the HIFLUGCS, an X-ray flux-limited sample, with available X-ray data from XMM-Newton. We search for correlations between the width of the temperature distributions and other cluster properties, including median cluster temperature, luminosity, size, presence ...

Focusing X‐Ray Optics for Astronomy

open access: yesX-Ray Optics and Instrumentation, Volume 2010, Issue 1, 2010., 2010
Focusing X‐ray telescopes have been the most important factor in X‐ray astronomy’s ascent to equality with optical and radio astronomy. They are the prime tool for studying thermal emission from very high temperature regions, non‐thermal synchrotron radiation from very high energy particles in magnetic fields and inverse Compton scattering of lower ...

Simulating galaxy clusters - I. Thermal and chemical properties of the intracluster medium [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2006
We have performed a series of N-body/hydrodynamical (TreeSPH) simulations of clusters and groups of galaxies, selected from cosmological N-body simulations within a $Λ$CDM framework: these objects have been re-simulated at higher resolution to $z$=0, in order to follow also the dynamical, thermal and chemical input on to the ICM from stellar ...

Metal distribution in the intracluster medium: a comprehensive numerical study of twelve galaxy clusters [PDF]

open access: yesAstronomy & Astrophysics, 2014
We present a simulation setup for studying the dynamical and chemical evolution of the intracluster medium (ICM) and analyze a sample of 12 galaxy clusters that are diverse both kinetically (pre-merger, merging, virialized) and in total mass (M vir = 1.17 × 1014 − 1.06 × 1015 M ⊙ ).

The Relationship Between Brightest Cluster Galaxy Star Formation and the Intracluster Medium in CLASH [PDF]

open access: yesThe Astrophysical Journal, 2017
Abstract We study the nature of feedback mechanisms in the 11 CLASH brightest cluster galaxies (BCGs) that exhibit extended ultraviolet and nebular line emission features. We estimate star formation rates (SFRs), dust masses, and starburst durations using a Bayesian photometry-fitting technique that accounts for both stellar and dust ...

Quasi-spiral solution to the mixed intracluster medium and the universal entropy profile of galaxy clusters

open access: yesMonthly Notices of the Royal Astronomical Society, 2023
ABSTRACT Well-resolved galaxy clusters often show a large-scale quasi-spiral structure in deprojected density ρ and temperature T fields, delineated by a tangential discontinuity known as a cold front, superimposed on a universal radial entropy profile with a linear K(r) ∝ Tρ−2/3 ∝ r adiabat.
