Book Description
One of the most vital observational clues for unraveling the origin of Brightest Cluster Galaxies (BCG) is the observed alignment of the BCGs with their host cluster and its surroundings. We have examined the BCG-cluster alignment effect, using clusters of galaxies detected from the Sloan Digital Sky Survey (SDSS). We find that the BCGs are preferentially aligned with the principal axis of their hosts, to a much higher redshift (z> ̃0.3) than probed by previous studies (z

Investigating the Binggeli Effect
Tracing Cosmic Evolution with Galaxy Clusters
Author: Stefano Borgani
Publisher:
ISBN:
Category : Science
Languages : en
Pages : 528
Book Description
Annotation International astronomers provide an overview of multiwavelength studies of galaxy clusters including optical, X-ray to UV, near- and far-IR, sub-mm, and radio bands. The contributions emphasize two complementary aspects of clusters of galaxies: large-scale views that help trace the structure of the Universe, and enormous astrophysical laboratories that reveal the history of cosmic baryons and the processes of galaxy formation. Borgani and Mezzetti (both astronomy, U. of Trieste, Italy) edit topics including cluster formations of radio loud quasars, mass-to-light ratio of galaxy systems, and Butcher-Oemler effect in high redshift X-ray selected clusters. The volume has no subject index. Annotation (c)2003 Book News, Inc., Portland, OR (booknews.com)

Merging Processes in Galaxy Clusters
Author: L. Feretti
Publisher: Springer Science & Business Media
ISBN: 0306480964
Category : Science
Languages : en
Pages : 329
Book Description
Mergers are the mechanisms by which galaxy clusters are assembled through the hierarchical growth of smaller clusters and groups. Major cluster mergers are the most energetic events in the Universe since the Big Bang. Many of the observed properties of clusters depend on the physics of the merging process. These include substructure, shock, intra cluster plasma temperature and entropy structure, mixing of heavy elements within the intra cluster medium, acceleration of high-energy particles, formation of radio halos and the effects on the galaxy radio emission. This book reviews our current understanding of cluster merging from an observational and theoretical perspective, and is appropriate for both graduate students and researchers in the field.

The Distribution of the Galaxies
Author: William C. Saslaw
Publisher: Cambridge University Press
ISBN: 0521394260
Category : Science
Languages : en
Pages : 524
Book Description
This topical volume examines one of the leading problems in astronomy - how galaxies cluster in our Universe. This book, first published in 2000, describes gravitational theory, computer simulations and observations related to galaxy distribution functions. It embeds distribution functions in a broader astronomical context, including other exciting contemporary topics such as correlation functions, fractals, bound clusters, topology, percolation and minimal spanning trees. Key results are derived and the necessary gravitational physics provided to ensure the book is self-contained. Throughout the book, theory, computer simulation and observation are carefully interwoven and critically compared. The book also shows how future observations can test the theoretical models for the evolution of galaxy clustering at early times in our Universe. This clear and authoritative volume is written at a level suitable for graduate students, and will be of key interest to astronomers, cosmologists, physicists and applied statisticians.
