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…
