Euclid Preparation. TBD. Impact of magnification on spectroscopic galaxy clustering

Euclid Collaboration, G. Jelic-Cizmek, F. Sorrenti +226

In this paper we investigate the impact of lensing magnification on the analysis of Euclid's spectroscopic survey, using the multipoles of the 2-point correlation function for gala…

Euclid preparation. XXXIX. The effect of baryons on the Halo Mass Function

Euclid Collaboration, T. Castro, S. Borgani +220

The Euclid photometric survey of galaxy clusters stands as a powerful cosmological tool, with the capacity to significantly propel our understanding of the Universe. Despite being…

COSMOGRAIL XIX: Time delays in 18 strongly lensed quasars from 15 years of optical monitoring

M. Millon, F. Courbin, V. Bonvin +16

We present the results of 15 years of monitoring lensed quasars, which was conducted by the COSMOGRAIL programme at the Leonhard Euler 1.2m Swiss Telescope. The decade-long light c…

COSMOGRAIL XVIII: time delays of the quadruply lensed quasar WFI2033-4723

V. Bonvin, M. Millon, J. H. H. Chan +26

We present new measurements of the time delays of WFI2033-4723. The data sets used in this work include 14 years of data taken at the 1.2m Leonhard Euler Swiss telescope, 13 years…

Euclid Preparation IV. Impact of undetected galaxies on weak-lensing shear measurements

Euclid Collaboration, N. Martinet, T. Schrabback +22

In modern weak-lensing surveys, the common approach to correct for residual systematic biases in the shear is to calibrate shape measurement algorithms using simulations. These sim…

KiDS+VIKING-450: Cosmic shear tomography with optical+infrared data

H. Hildebrandt, F. Köhlinger, J. L. van den Busch +25

We present a tomographic cosmic shear analysis of the Kilo-Degree Survey (KiDS) combined with the VISTA Kilo-Degree Infrared Galaxy Survey (VIKING). This is the first time that a f…
