Poor galaxy cluster
WebHubble Space Telescope imaging for 26 giant early-type galaxies, all drawn from the MAST archive, is used to carry out photometry of their surrounding globular cluster (GC) systems. Most of these targets are Brightest Cluster Galaxies and their distances range from 24-210 Mpc. The catalogs of photometry, completed with DOLPHOT, are publicly available.

WebMar 2, 2007 · 2 March 2007. The NASA/ESA Hubble Space Telescope, in collaboration with several other ground- and space-based telescopes, has captured a galaxy being ripped apart by a galaxy cluster's gravitational field and harsh environment. The finding sheds light on the mysterious process by which gas-rich spiral-shaped galaxies might evolve into gas-poor ... WebClusters of galaxies are bound, virialized, high overdensity systems of galaxies, held together by the clusters self gravity. Rich clusters contain, by traditional definition ( Abell 1958 ), at least 30 galaxies brighter than m3 + 2 m (where m3 is the magnitude of the third brightest cluster member) within a radius of R 1.5 h-1 Mpc of the ...

We use the similarity of the velocity-dispersion profiles at small radii and the cD-like galaxies' internal velocity dispersions to argue that cD formation is a local phenomenon. imd world competitiveness yearbook 2020 pdfA supercluster is a large group of smaller galaxy clusters or galaxy groups; they are among the largest known structures in the universe. The Milky Way is part of the Local Group galaxy group (which contains more than 54 galaxies), which in turn is part of the Virgo Supercluster, which is part of the Laniakea Supercluster.
