TL;DR: In this article, the authors present the quantitative rest-frame B morphological evolution and galaxy merger fraction at 0.2 1011 L 2.5% of the merged galaxies are disk galaxies and only 15% are considered major merger candidates.
Journal ArticleDOI
Galaxies at the extremes: ultra-diffuse galaxies in the virgo cluster
Chris Mihos,Patrick R. Durrell,Laura Ferrarese,John J. Feldmeier,Patrick Côté,Eric W. Peng,Paul Harding,Chengze Liu,Stephen D. J. Gwyn,Jean-Charles Cuillandre +9 more
TL;DR: In this paper, the authors reported the discovery of three large ( 1′) extremely low surface brightness (LSB; ) galaxies identified using our deep, wide-field imaging of the Virgo Cluster from the Burrell Schmidt telescope.
Journal ArticleDOI
Cosmic shear analysis with CFHTLS deep data

TL;DR: In this paper, the first cosmic shear measurements obtained from the T0001 release of the Canada-France-Hawaii Telescope Legacy Survey are presented, which covers three uncorrelated patches (D1, D3 and D4) of one square degree each, observed in u*, g, r, i' and z' bands, to a depth of i' = 25.5.
Journal ArticleDOI
The VIRMOS deep imaging survey: II: CFH12K BVRI optical data for the 0226-04 deep field
H. J. McCracken,M. Radovich,E. Bertin,Yannick Mellier,M. Dantel-Fort,O. Le Fevre,Jean-Charles Cuillandre,Stephen D. J. Gwyn,Sylvie Foucaud,G. Zamorani +9 more
TL;DR: In this article, the authors describe the reduction, preparation and reliability of the photometric catalogues which comprise the CFH12K-VIRMOS deep field, and demonstrate their catalogues are free from systematic biases and are complete and reliable down these limits.
