Lensing Without Borders. I. A Blind Comparison of the Amplitude of Galaxy-Galaxy Lensing Between Independent Imaging Surveys
A. Leauthaud, A. Amon, S. Singh +104
Lensing Without Borders is a cross-survey collaboration created to assess the consistency of galaxy-galaxy lensing signals () across different data-sets and to carry out end-to…
Euclid preparation: XVIII. Cosmic Dawn Survey. Spitzer observations of the Euclid deep fields and calibration fields
Andrea Moneti, H. J. McCracken, M. Shuntov +194
We present a new infrared survey covering the three Euclid deep fields and four other Euclid calibration fields using Spitzer's Infrared Array Camera (IRAC). We have combined these…
The dark matter halo masses of elliptical galaxies as a function of observationally robust quantities
Alessandro Sonnenfeld, Crescenzo Tortora, Henk Hoekstra +9
Context. The assembly history of the stellar component of a massive elliptical galaxy is closely related to that of its dark matter halo. Measuring how the properties of galaxies c…
Pure-mode correlation functions for cosmic shear and application to KiDS-1000
Peter Schneider, Marika Asgari, Yasaman Najafi Jozani +10
One probe for systematic effects in gravitational lensing surveys is the presence of so-called B-modes in the cosmic shear two-point correlation functions ξ_\pm(\vt), since lensing…
Euclid preparation: XIX. Impact of magnification on photometric galaxy clustering
F. Lepori, I. Tutusaus, C. Viglione +183
We investigate the importance of lensing magnification for estimates of galaxy clustering and its cross-correlation with shear for the photometric sample of Euclid. Using updated s…
High-quality strong lens candidates in the final Kilo Degree survey footprint
R. Li, N. R. Napolitano, C. Spiniello +16
We present 97 new high-quality strong lensing candidates found in the final , that completed the full area of the Kilo-Degree Survey (Ki…
