Lensing without mixing: Probing baryonic acoustic oscillations and other scale-dependent features in cosmic shear surveys
David Touzeau, Alexandre Barthelemy, Francis Bernardeau
Weak-gravitational lensing tends to wash out scale- and time-dependent features of the clustering of matter, such as the baryonic acoustic oscillations which appear in the form of…
Cosmic shear nulling as a geometrical cosmological probe: Methodology and sensitivity to cosmological parameters and systematics
David Touzeau, Francis Bernardeau, Karim Benabed +1
Tomographic weak lensing surveys contain intrinsic symmetries that depend solely on the geometric structure of the Universe. These symmetries can be revealed through null tests and…
Novel geometrical test of cosmological expansion from photometric data
David Touzeau, Francis Bernardeau, Karim Benabed +1
Aim. In tomographic cosmic-shear observations, the Bernardeau, Nishimichi, Taruya (BNT) transform allows us to build weak lensing transformed maps for which the contribution from l…
