KiDS-Legacy: The consistency test of the large-scale structure with Bernardeau-Nishimichi-Taruya transform
Shiming Gu, Ziang Yan, Ludovic van Waerbeke +10
We perform the first -cut cosmic shear analysis of the KiDS-Legacy survey. This method uses the Bernardeau-Nishimichi-Taruya (BNT) transform to construct weak-lensing kernels th…
The Back-in-time Void Finder: dynamical identification of cosmic voids through optimal transport reconstruction
Simone Sartori, Sofia Contarini, Elena Sarpa +4
Cosmic voids have increasingly emerged as a powerful cosmological probe. However, their large spatial extent and intrinsically underdense environments make their identification hig…
Beyond general relativity: probing gravity with gravitational redshifts
Eleni Tsaprazi, Giorgio F. Lesci, Federico Marulli +7
Despite the success of general relativity (GR), the unexplained nature of dark energy on cosmological scales leaves open the question of whether GR provides a complete description…
Weak-lensing tunnel voids in simulated light cones: A new pipeline to investigate modified gravity and massive neutrinos signatures
Leonardo Maggiore, Sofia Contarini, Carlo Giocoli +1
Cosmic voids offer a unique opportunity to explore modified gravity (MG) models. Their low-density nature and vast extent make them especially sensitive to cosmological scenarios o…
A revisited Correction to the Halo Mass Function for local-type Primordial non-Gaussianity
Luca Fiorino, Sofia Contarini, Federico Marulli +4
We investigate the effect of primordial non-Gaussianities on halo number counts using N-body simulations with different values of . We show how current theore…
