Star formation efficiency in galaxy clusters
T. F. Lagana, G. B. Lima Neto, F. Andrade-Santos +1
The luminous material in clusters of galaxies falls primarily into two forms: the visible galaxies and the X-ray emitting intra-cluster medium. The hot intra-cluster gas is the maj…
An extension of the SHARC survey
C. Adami, M. P. Ulmer, F. Durret +2
We report on our search for distant clusters of galaxies based on optical and X-ray follow up observations of X-ray candidates from the SHARC survey. Based on the assumption that t…
Photo-z for weak lensing tomography from space: the role of optical and near-IR photometry
F. B. Abdalla, A. Amara, P. Capak +3
We study in detail the photometric redshift requirements needed for tomographic weak gravitational lensing in order to measure accurately the Dark Energy equation of state. In part…
Searching High Redshift Large-Scale Structures: Photometry of Four Fields Around Quasar Pairs at z~1
N. V. Boris, L. Sodre, E. S. Cypriano +3
We have studied the photometric properties of four fields around the high-redshift quasar pairs QP1310+0007, QP1355-0032, QP0110-0219, and QP0114-3140 at z ~ 1 with the aim of iden…
The dynamical state of massive galaxy clusters
E. S. Cypriano, L. Sodre, J. -P. Kneib +1
We study the mass distribution of a sample of 24 X-ray bright Abell clusters through weak gravitational lensing. This method is independent of the dynamical state of the galaxy clu…
Velocity dispersion, mass and the luminosity function of the fossil cluster RX J1416.4+2315
Eduardo S. Cypriano, Claudia L. Mendes de Oliveira, Laerte Sodré
We study the properties of the fossil cluster RX J1416.4+2315 through g' and i'-band imaging and spectroscopy of 25 member galaxies. The system is at a mean redshift of 0.137 and h…
