Towards precision cosmology with Void x CMB correlations (II): Impact of mock catalogs on the Void x CMB lensing signal
Mar Pérez Sar, Carlos Hernández Monteagudo, András Kovács +2
Gravitational lensing by large-scale structure imprints secondary anisotropies on the Cosmic Microwave Background (CMB) that can be exploited to probe cosmology. In particular, cos…

Biasing from galaxy trough and peak profiles with the DES Y3 redMaGiC galaxies and the weak lensing mass map
Q. Hang, N. Jeffrey, L. Whiteway +83
We measure the correspondence between the distribution of galaxies and matter around troughs and peaks in the projected galaxy density, by comparing \texttt{redMaGiC} galaxies ($0.…

The Gravitational Lensing Imprints of DES Y3 Superstructures on the CMB: A Matched Filtering Approach
Umut Demirbozan, Seshadri Nadathur, Ismael Ferrero +63
Low density cosmic voids gravitationally lens the cosmic microwave background (CMB), leaving a negative imprint on the CMB convergence . This effect provides insight into the…
