CMB lensing imprints of cosmic voids in DESI Legacy Survey DR9 LRGs with photometric redshift calibration
Simone Sartori
The lensing imprint of cosmic voids in the Cosmic Microwave Background (CMB) provides a powerful test of the CDM model. However, recent studies report a "lensing-is-low" tensio…
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…
Kinematic lensing with high-resolution spectroscopic surveys. A unique opportunity for transformative cosmology at high redshifts in the 2040s
Stefano Camera, Martin Kilbinger, Jean-Paul Kneib +10
We present a science case to perform high-redshift cosmic shear surveys for cosmology with next-generation spectroscopic instruments, such as the proposed MegaMapper and Wide-field…
Probing General Relativity on Cosmological Scales in the 2040s
Federico Montano, Samantha J. Rossiter, Chris Addis +18
General relativity is exquisitely tested in strong-field regimes, yet its validity on cosmological scales remains largely unexplored. Upcoming wide and deep large-scale structure s…
Beyond Stage IV: Quasar and Galaxy Clustering and the Fundamental Physics of the 2040s
M. Guidi, M. Moresco, H. K. Herrera-Alcantar +24
Stage IV galaxy surveys (DESI, 4MOST, MOONS, Euclid) are establishing precision constraints on cosmological parameters through baryon acoustic oscillations and redshift-space disto…
The imprint of cosmic voids from the DESI Legacy Survey DR9 LRGs in the Planck 2018 lensing map through spectroscopically calibrated mocks
S. Sartori, P. Vielzeuf, S. Escoffier +31
The cross-correlation of cosmic voids with the lensing convergence () map of the Cosmic Microwave Background (CMB) fluctuations provides a powerful tool to refine our understan…
