The growth of the galaxy cluster Abell 85: mergers, shocks, stripping and seeding of clumping [PDF]
, 2014 We present the results of deep Chandra, XMM-Newton and Suzaku observations of the nearby galaxy cluster Abell 85, which is currently undergoing at least two mergers, and in addition shows evidence for gas sloshing which extends out to r ~ 600 kpc. One of

The JWST PEARLS View of the El Gordo Galaxy Cluster and of the Structure It Magnifies
The Astrophysical Journal, 2023 The massive galaxy cluster El Gordo ( z = 0.87) imprints multitudes of gravitationally lensed arcs onto James Webb Space Telescope Near-Infrared Camera (NIRCam) images.

Internal dynamics of the galaxy cluster Abell 545
, 2011 Diffuse radio emission in galaxy clusters, and their connection with cluster mergers, are still debated. We seek to explore the internal dynamics of the radio halo cluster Abell 545.

The reversal of the SF–density relation in a massive, X-ray-selected galaxy cluster at z = 1.58: results from Herschel [PDF]
, 2014 Dusty, star-forming galaxies have a critical role in the formation and evolution of massive galaxies in the Universe. Using deep far-infrared imaging in the range 100-500um obtained with the Herschel telescope, we investigate the dust-obscured star ...

A Formation Mechanism for “Wrong Way” Radio Relics
The Astrophysical Journal Letters, 2023 Radio relics are typically found to be arc-like regions of synchrotron emission in the outskirts of merging galaxy clusters, bowing out from the cluster center.

Alignment and morphology of elliptical galaxies: the influence of the cluster tidal field
, 1994 We investigate two possible effects of the tidal field induced by a spherical cluster on its elliptical galaxy members: the modification of the ellipticity of a spherical galaxy and the isophotal alignment in the cluster radial direction of a misaligned ...

Galactic cannibalism and CDM density profiles [PDF]
, 2004 Using N-body simulations we show that the process of formation of the brightest cluster galaxy through dissipationless galactic cannibalism can affect the inner cluster dark matter density profile.

Hubble Frontier Fields: a high-precision strong-lensing analysis of the massive galaxy cluster Abell 2744 using ∼180 multiple images [PDF]
, 2014 We present a high-precision mass model of galaxy cluster Abell 2744, based on a strong gravitational-lensing analysis of the Hubble Space Telescope Frontier Fields (HFF) imaging data, which now include both Advanced Camera for Surveys and Wide Field ...

Cosmology with Clusters of Galaxies [PDF]
, 2008 In this Chapter I review the role that galaxy clusters play as tools to constrain cosmological parameters. I will concentrate mostly on the application of the mass function of galaxy clusters, while other methods, such as that based on the baryon fraction, are covered by other Chapters of the book.
