    Clusters of galaxies occupy a special place in the hierarchy of cosmic structures. They arise from the collapse of initial perturbations having a typical comoving scale of about 1Cited by: Abstract: The physical origin of the near-ultraviolet MgII emission remains an under-explored domain, contrary to more typical emission lines detected in the spectra of star-forming galaxies. We explore the nebular and physical properties for a sample of galaxies between z drawn from the MUSE Hubble Ultra Deep Survey.

    The Black Eye Galaxy (also called Evil Eye Galaxy and designated Mess M64, or NGC ) is a relatively isolated spiral galaxy located 17 million light years away in the northern constellation of Coma was discovered by Edward Pigott in March , and independently by Johann Elert Bode in April of the same year, as well as by Charles Messier in Constellation: Coma Berenices. The study of galaxies across cosmic time encompasses the main constituents of the universe across 90 percent of its history, from the formation and evolution of structures such as galaxies, clusters of galaxies, and the “cosmic web” of intergalactic matter, to the stars, gas, dust, supermassive black holes, and dark matter of which they are composed.

The Abell clusters have been tabulated with up-to-date information by Struble and Rood (ApJSu and ). The survey of clusters was extended to the southern sky by Abell, Corwin, and Olowin (ApJSu 1; CDS digital version), producing the first reasonably complete all-sky catalog of nearby clusters (some as far away as z.

the clusters in the A complex are most likely in a pre-merger stage, as suggested by the X-ray properties (Gastaldello et al.) and by the properties of the radio galaxies (Lakhchaura et al., Di Gennaro et al.): the radio emission from the BCGs (Brightest Cluster Galaxies) in A and A is typical of very relaxed systems; i.e Cited by: 1.

One other source of X-ray emission in early type galaxies are X-ray binary stars, with 24 sources being detected in the inner area of NGC [6] NGC is home to a large number of globular clusters, with their total number estimated to be ±compared to – in and around the Milky llation: Eridanus.

Each cluster is filled with a large-scale plasma atmosphere, in which primordial matter is mixed with matter that has been processed inside stars. This is a wonderful plasma physics laboratory.

Our diagnostics are the data we obtain from x-ray and radio telescopes. The thermal plasma is a strong x-ray source Cited by: 4.Retrieved abstracts, starting with number Total number selected:
