SPT-3G D1: Quadratic-Estimator CMB Lensing Reconstruction and Cosmology

Y. Omori, W. L. K. Wu, Y. Nakato +92

We present a map of the cosmic microwave background (CMB) lensing potential reconstructed from observations taken during the 2019 and 2020 seasons with the third-generation camera…

SPT-3G D1: Foreground-Robust Lensing Templates for Primordial Gravitational Wave Searches

Y. Nakato, W. L. K. Wu, Y. Omori +92

Gravitational lensing of the cosmic microwave background (CMB) generates B-mode polarization that acts as a source of contamination to searches for B modes generated by primordial…

CMB Lensing Reconstruction Using Two Years of Temperature Data from the SPT-3G Summer Survey

K. Levy, S. Raghunathan, F. Guidi +91

We present the first reconstruction of the cosmic microwave background (CMB) lensing potential from the SPT-3G Summer survey using two years of temperature data. The Summer survey…

Cross-correlation of SPT-3G D1 CMB lensing and DES Y3 galaxy lensing

A. Ouellette, Y. Omori, E. Anderes +92

Measurements of the weak lensing of galaxies and of the cosmic microwave background (CMB) provide direct probes of the cosmic matter density field, but the two observables are sens…

SPT-3G D1: Maps of the millimeter-wave sky from 2019 and 2020 observations of the SPT-3G Main field

W. Quan, E. Camphuis, C. Daley +92

Maps of the sky in millimeter wavelengths contain rich information on cosmology through anisotropies of the cosmic microwave background (CMB). Creating multifrequency sky maps of a…

Towards constraining cosmological parameters with SPT-3G observations of 25% of the sky

A. Vitrier, K. Fichman, L. Balkenhol +103

The South Pole Telescope (SPT), using its third-generation camera, SPT-3G, is conducting observations of the cosmic microwave background (CMB) in temperature and polarization acros…

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

Aim. In tomographic cosmic-shear observations, the Bernardeau, Nishimichi, Taruya (BNT) transform allows us to build weak lensing transformed maps for which the contribution from l…
