The Nature of Blue Cores in Spheroids: a Possible Connection with AGN and Star Formation
Felipe Menanteau, Andre R. Martel, Paolo Tozzi +9
We investigate the physical nature of blue cores in early-type galaxies through the first multi-wavelength analysis of a serendipitously discovered field blue-nucleated spheroid in…
Strong lensing analysis of A1689 from deep ACS images
Keren Sharon, Tom J. Broadhurst, Narciso Benitez +3
ACS observations of massive lensing clusters permit an order of magnitude increase in the numbers of multiply-lensed background galaxies identified behind a given cluster. We have…
Strong Lensing Analysis of A1689 from Deep Advanced Camera Images
Tom Broadhurst, Narciso Benitez, Dan Coe +6
We analyse deep multi-colour Advanced Camera images of the largest known gravitational lens, A1689. Radial and tangential arcs delineate the critical curves in unprecedented detail…
Ultra Compact Dwarf galaxies in Abell 1689: a photometric study with the ACS
S. Mieske, L. Infante, N. Benitez +37
The properties of Ultra Compact Dwarf (UCD) galaxy candidates in Abell 1689 (z=0.183) are investigated, based on deep high resolution ACS images. A UCD candidate has to be unresolv…
