PySCo-EFT and ECOSMOG-EFT: a tandem of N-body simulation codes for the Effective Field Theory of Dark Energy
Himanish Ganjoo, Yann Rasera, Emilio Bellini +18
Modified gravity theories constitute viable alternatives to the standard cosmological model for explaining the observed late-time accelerated expansion of the Universe. The Effecti…
Generative modeling of convergence maps based on predicted one-point statistics
Vilasini Tinnaneri Sreekanth, Jean-Luc Starck, Sandrine Codis
Context: Weak gravitational lensing is a key cosmological probe for current and future large-scale surveys. While power spectra are commonly used for analyses, they fail to capture…
Clustering of the extreme: A theoretical description of weak lensing critical points power spectra in the mildly nonlinear regime
Zhengyangguang Gong, Alexandre Barthelemy, Sandrine Codis
In cosmic web analysis, complementary to traditional cosmological probes, the extrema (e.g. peaks and voids) two-point correlation functions (2PCFs) are of particular interest for…
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
In tomographic cosmic-shear observations, the BNT (Bernardeau, Nishimichi, Taruya) transform, Bernardeau et al. (2014), allows to build weak lensing transformed maps for which the…
Theoretical wavelet -norm from one-point PDF prediction
Vilasini Tinnaneri Sreekanth, Sandrine Codis, Alexandre Barthelemy +1
Weak gravitational lensing, resulting from the bending of light due to the presence of matter along the line of sight, is a potent tool for exploring large-scale structures, partic…
