... 633Slee+ Fifty-eight fields near rich clusters of galaxies were surveyed with the Very Large Array using scaled arrays in the B/C and/or C/D configurations at 1.5 GHz and 4.9 GHz. The fields were centered on steep spectrum sources in or near clusters that were earlier surveyed with lower resolution telescopes. ... The columns are : . Column 1 Cluster Field (Z1518 = Zw1518.8+0747) . Column 2 distance of source from cluster centre in Abell radii . ... Column 5 1.5 GHz flux (mJy) . ...

... Programme . ... Abstract: Globular clusters can probe the formation history of galaxies by providing evidence for the chemical evolution and major episodes of star formation in their host galaxies, by examining their kinematic signatures, as well as their structural parameters. ... The giant elliptical NGC 5128 (Centaurus A), at a mere 4 Mpc away, gives us the only opportunity to study in extensive detail the globular cluster system of a recent merger galaxy. ...

The fundamental properties of early-type galaxies in the Coma Cluster S.A.W. Moore et al. University of Durham, U.K. Co-authors: Lucey, J.R.; Colless, M.; Kuntschner, H.; Bower, R.; Davies, R.L. Early-type galaxies in clusters exhibit remarkably tight correlations between their global properties, e.g. the colour- magnitude relation, the Mg2 - relation and the Fundamental Plane. ... In addition, these data provide a baseline for evolutionary studies of distant clusters. ...

Results from 6m telescope observations of globular clusters in dwarf galaxies Sharina M. We consider properties of globular clusters in dwarf galaxies observed with the multi-slit unit of the SCORPIO spectrograph at the SAO 6m telescope. ... Studying GCs in dwarf galaxies at the faintest end of the galaxy luminosity function provides valuable information for a better understanding of galaxy evolution and evolutionary connection between globular clusters and nuclei of galaxies. ...

Astronotes Armagh Planetarium's Stellar Blog! ... Stars . ... Starbursts are short-lived events, stars are forming so quickly that the reservoirs of interstellar gas from which stars are coalescing would be used up on a timescale much shorter than the age of the galaxy . ... Strong stellar winds from giant new stars in the starburst region combine with the blasts of supernovae to push a mighty flood of extremely hot gas, a ?superwind? from the galaxy thousands of light years into intergalactic space. ...

... Our Milky Way galaxy is host to a number of companions. These companions are gravitationally bound to the Milky Way and are stellar systems in their own right. They include a population of about 150 globular clusters (GCs) and some 30 dwarf satellite galaxies (DSGs). ... These DSGs are more extended and diffuse compared to GCs. In fact the larger satellites of the Milky Way (and other galaxies, for that matter) host their own small systems of GCs. ...
