Journal ArticleDOI
Galaxy threshing and the formation of ultracompact dwarf galaxies
TL;DR: In this article, the authors performed numerical simulations on the dynamical evolution of nucleated dwarf galaxies orbiting NGC 1399 and suffering from its strong tidal gravitational field and found that the outer stellar components of a nucleated dwarfs are totally removed.
Journal ArticleDOI

TL;DR: The 2dF Galaxy Redshift Survey (2dFGRS) has obtained spectra for 245591 sources, mainly galaxies, brighter than a nominal extinction-corrected magnitude limit of b_J=19.45 as mentioned in this paper.
Journal ArticleDOI
The dissection of abell 2744: a rich cluster growing through major and minor mergers
TL;DR: In this article, Chandra X-ray data and extensive optical spectroscopy, obtained with AAOmega on the 3.9 m Anglo-Australian Telescope, are used to study the complex merger taking place in the galaxy cluster Abell 2744.
Journal ArticleDOI

Ian Smail,Ian Smail,Alan Dressler,Warrick J. Couch,Richard S. Ellis,Augustus Oemler,Augustus Oemler,Harvey Butcher,Ray M. Sharples +8 more
TL;DR: In this article, the authors presented a catalog of objects detected in deep images of 11 fields in 10 distant clusters obtained using WFPC-2 on board the Hubble Space Telescope.
