Combining strong and weak lensing estimates in the Cosmos field
Felix Arjun Kuhn, Claudio Bruderer, Simon Birrer +2
We present a combined cosmic shear analysis of the modeling of line-of-sight distortions on strongly lensed extended arcs and galaxy shape measurements in the COSMOS field. We deve…
Fast Lightcones for Combined Cosmological Probes
Raphael Sgier, Janis Fluri, Jörg Herbel +4
The combination of different cosmological probes offers stringent tests of the CDM model and enhanced control of systematics. For this purpose, we present an extension of the li…
Cosmological model discrimination with Deep Learning
Jorit Schmelzle, Aurelien Lucchi, Tomasz Kacprzak +4
We demonstrate the potential of Deep Learning methods for measurements of cosmological parameters from density fields, focusing on the extraction of non-Gaussian information. We co…
An Ultra Fast Image Generator (UFig) for wide-field astronomy
Joel Bergé, Lukas Gamper, Alexandre Réfrégier +1
Simulated wide-field images are becoming an important part of observational astronomy, either to prepare for new surveys or to test measurement methods. In order to efficiently exp…
Cosmic shear requirements on the wavelength-dependence of telescope point spread functions
E. S. Cypriano, A. Amara, L. M. Voigt +5
Cosmic shear requires high precision measurement of galaxy shapes in the presence of the observational Point Spread Function (PSF) that smears out the image. The PSF must therefore…
Cosmic Shear Systematics: Software-Hardware Balance
A. Amara, A. Refregier, S. Paulin-Henriksson
Cosmic shear measurements rely on our ability to measure and correct the Point Spread Function (PSF) of the observations. This PSF is measured using stars in the field, which give…
