IDCS J1426.5+3508: SUNYAEV-ZEL’DOVICH MEASUREMENT OF A MASSIVE INFRARED-SELECTED CLUSTER AT z = 1.75
We report 31 GHz CARMA observations of IDCS J1426.5+3508, an infrared-selected galaxy cluster at z = 1.75. A Sunyaev-Zel'dovich (SZ) decrement is detected toward this cluster, indicating a total massExpand

Strong lensing in the MARENOSTRUM UNIVERSE - I. Biases in the cluster lens population
Context. Strong lensing is one of the most direct probes of mass distribution in the inner regions of galaxy clusters. It can be used to constrain the density profiles and to measure the mass of theExpand

Strong lensing statistics and the power spectrum normalisation
We use semi-analytic modelling of the galaxy-cluster population and its strong lensing efficiency to explore how the expected abundance of large gravitational arcs on the sky depends on σ 8 . OurExpand

IDCS J1426.5+3508: COSMOLOGICAL IMPLICATIONS OF A MASSIVE, STRONG LENSING CLUSTER AT z = 1.75
The galaxy cluster IDCS J1426.5+3508 at z = 1.75 is the most massive galaxy cluster yet discovered at z > 1.4 and the first cluster at this epoch for which the Sunyaev-Zel'Dovich effect has beenExpand

Next Generation Cosmology: Constraints from the Euclid Galaxy Cluster Survey
We study the characteristics of the galaxy cluster samples expected from the European Space Agency's Euclid satellite and forecast constraints on parameters describing a variety of cosmologicalExpand

The strongest gravitational lenses - I. The statistical impact of cluster mergers
For more than a decade now, it has been controversial whether or not the high rate of giant gravitational arcs and the largest observed Einstein radii are consistent with the standard cosmologicalExpand

The effects of baryonic cooling on the concentration–mass relation
I re-examine the relation between virial mass and concentration for groups and clusters of galaxies as measured in a number of recent works. As previously noted by several authors, low-mass clustersExpand

The potential of X-ray cluster surveys to constrain primordial non-Gaussianity
We present forecasts for constraints on deviations from Gaussian distribution of primordial density perturbations from future high‐sensitivity X‐ray surveys of galaxy clusters. Our analysis is basedExpand

A fast method for computing strong-lensing cross sections: application to merging clusters
Astronomy & Astrophysics, submitted Abstract. Strong gravitational lensing by irregular mass distributi ons, such as galaxy clusters, is generally not well quantifie d by cross sections of analyticExpand
