Journal ArticleDOI
The 2dF Galaxy Redshift Survey: The blue galaxy fraction and implications for the Butcher-Oemler effect
Roberto De Propris,Matthew Colless,John A. Peacock,Warrick J. Couch,Simon P. Driver,Michael L. Balogh,Ivan K. Baldry,Carlton M. Baugh,Joss Bland-Hawthorn,Terry J. Bridges,Russell D. Cannon,Shaun Cole,Chris A. Collins,Nicholas Cross,Gavin Dalton,Gavin Dalton,George Efstathiou,Richard S. Ellis,Carlos S. Frenk,Karl Glazebrook,Ed Hawkins,Carole Jackson,Ofer Lahav,Ian Lewis,Stuart Lumsden,Stephen J. Maddox,Darren Madgwick,Peder Norberg,Will J. Percival,Bruce A. Peterson,William J. Sutherland,Keith Taylor +31 more
TL;DR: In this paper, the authors derived the fraction of blue galaxies in a sample of clusters at z < 0.11 and the general field at the same redshift and showed that the value of the blue fraction is observed to depend on the luminosity limit adopted, cluster-centric radius and, more generally, local galaxy density, but does not depend on cluster properties.
Journal ArticleDOI
Scaling relations for galaxy clusters
Chiara Marmo,Giovanni Fasano,E. Pignatelli,Bianca M. Poggianti,Daniela Bettoni,C. Halliday,Jesús A. Varela,Mariano Moles,Per Kjaergaard,Warrick J. Couch,Alan Dressler +10 more
TL;DR: In this article, the results of the WINGS survey were used to obtain determinations of optical scaling relations for galaxy clusters, focusing on the Kormendy relation and the fundamental plane.
Journal ArticleDOI
WINGS: a WIde-field nearby Galaxy-cluster survey III. Deep near-infrared photometry of 28 nearby clusters
T. Valentinuzzi,D. Woods,D. Woods,G. Fasano,M. Riello,Mauro D'Onofrio,Jesus Varela,Daniela Bettoni,Antonio Cava,Antonio Cava,Warrick J. Couch,Alan Dressler,Jacopo Fritz,Mariano Moles,A. Omizzolo,Bianca M. Poggianti,Per Kjaergaard +16 more
TL;DR: In this article, the authors presented the near-infrared (J,K) photometric catalogs of 28 clusters of the WINGS sample and described the procedures followed to construct them.
Journal ArticleDOI
A Statistical Comparison of Line Strength Variations in Coma and Cluster Galaxies at z ~ 0.3
Lewis A. Jones,Warrick J. Couch +1 more
TL;DR: In this article, a statistical comparison between spectral line strength variations in Coma galaxies and galaxies in three rich clusters at z = 0.3 is presented, which suggests that galaxies in clusters have been homogenised such that most of the information from the conditions present at their formation has been destroyed.
Journal ArticleDOI
The globular clusters and star formation history of the isolated, quiescent ultra-diffuse galaxy DGSAT I
Steven Janssens,Aaron J. Romanowsky,Roberto Abraham,Jean P. Brodie,Warrick J. Couch,Duncan A. Forbes,Seppo Laine,D. Mart'inez-Delgado,Pieter G. van Dokkum +8 more
TL;DR: In this paper , the isolated, quiescent ultra-diffuse galaxy (UDG) DGSAT I and its globular cluster (GC) system using two orbits of Hubble Space Telescope Advanced Camera for Surveys imaging in the F606W and F814W filters.
