Euclid Definition Study Report

- R. Laureijs, J. Amiaux, +216 authors E. Zucca
- Physics
- 14 October 2011

Euclid is a space-based survey mission from the European Space Agency designed to understand the origin of the Universe's accelerating expansion. It will use cosmological probes to investigate the… Expand

KiDS-450: cosmological parameter constraints from tomographic weak gravitational lensing

- H. Hildebrandt, M. Viola, +33 authors L. Waerbeke
- Physics
- 16 June 2016

We present cosmological parameter constraints from a tomographic weak gravitational lensing analysis of ~450deg$^2$ of imaging data from the Kilo Degree Survey (KiDS). For a flat $\Lambda$CDM… Expand

Gravitational Lensing: Strong, Weak and Micro

- G. Meylan, P. Jetzer, P. North, P. Schneider, C. Kochanek, J. Wambsganss
- Physics
- 2006

A NEW MEASURE FOR COSMIC SHEAR

- P. Schneider, L. Waerbeke, B. J. Kruse
- Physics
- 15 August 1997

Cosmic shear, i.e. the distortion of images of high-redshift galaxies through the tidal gravitational field of the large-scale matter distribution in the Universe, offers the opportunity to measure… Expand

Detection of (dark) matter concentrations via weak gravitational lensing

- P. Schneider
- Physics
- 10 January 1996

The distortion of images of faint background galaxies by (weak) gravitational lensing can be used to measure the mass distribution of the deflector. The image distortions can be used to define a… Expand

EDisCS - the ESO distant cluster survey. Sample definition and optical photometry

- S. White, D. Clowe, +23 authors D. Zaritsky
- Physics
- 16 August 2005

We present the ESO Distant Cluster Survey (EDisCS), a survey of 20 fields containing distant galaxy clusters with redshifts ranging from 0.4 to almost 1.0. Candidate clusters were chosen from among… Expand

Why your model parameter confidences might be too optimistic - unbiased estimation of the inverse covariance matrix

- J. Hartlap, P. Simon, P. Schneider
- Physics, Mathematics
- 2 August 2006

Aims. The maximum-likelihood method is the standard approach to obtain model fits to observational data and the corresponding confidence regions. We investigate possible sources of bias in the… Expand

Cosmic shear statistics and cosmology

- L. Waerbeke, Y. Mellier, +11 authors B. Fort
- Physics
- 29 January 2001

We report a measurement of cosmic shear correlations using an eective area of 6.5 deg 2 of the VIRMOS deep imaging survey in progress at the Canada-France-Hawaii Telescope. We measured various shear… Expand

Searching for galaxy clusters using the aperture mass statistics in 50 VLT fields

- M. Hetterscheidt, T. Erben, P. Schneider, R. Maoli, L. Waerbeke, Y. Mellier
- Physics
- 28 April 2005

Application of the aperture mass ( M ap -) statistics provides a weak lensing method for the detection of cluster-sized dark matter halos. We present a new aperture filter function and maximise the… Expand

Simulating the escaping atmospheres of hot gas planets in the solar neighborhood

- M. Salz, S. Czesla, P. Schneider, J. Schmitt
- Physics
- 30 November 2015

Absorption of high-energy radiation in planetary thermospheres is believed to lead to the formation of planetary winds. The resulting mass-loss rates can affect the evolution, particularly of small… Expand
