Strong detection of the CMB lensingxgalaxy weak lensingcross-correlation from ACT-DR4,PlanckLegacy and KiDS-1000
Naomi Clare Robertson, David Alonso, Joachim Harnois-Déraps +48
We measure the cross-correlation between galaxy weak lensing data from the Kilo Degree Survey (KiDS-1000, DR4) and cosmic microwave background (CMB) lensing data from the Atacama C…
The Simons Observatory: gain, bandpass and polarization-angle calibration requirements for B-mode searches
Maximilian H. Abitbol, David Alonso, Sara M. Simon +45
We quantify the calibration requirements for systematic uncertainties for next-generation ground-based observatories targeting the large-angle -mode polarization of the Cosmic M…
Cosmic shear power spectra in practice
Andrina Nicola, Carlos García-García, David Alonso +4
Cosmic shear is one of the most powerful probes of Dark Energy, targeted by several current and future galaxy surveys. Lensing shear, however, is only sampled at the positions of g…
The LSST DESC DC2 Simulated Sky Survey
LSST Dark Energy Science Collaboration, Bela Abolfathi, David Alonso +77
We describe the simulated sky survey underlying the second data challenge (DC2) carried out in preparation for analysis of the Vera C. Rubin Observatory Legacy Survey of Space and…
Cross-correlating radio continuum surveys and CMB lensing: constraining redshift distributions, galaxy bias and cosmology
David Alonso, Emilio Bellini, Catherine Hale +2
We measure the harmonic-space auto-power spectrum of the galaxy overdensity in the LOFAR Two-metre Sky Survey (LoTSS) First Data Release and its cross correlation with the map of t…
CMB-S4: Forecasting Constraints on Primordial Gravitational Waves
S4 Collaboration, Kevork Abazajian, Graeme E. Addison +233
CMB-S4---the next-generation ground-based cosmic microwave background (CMB) experiment---is set to significantly advance the sensitivity of CMB measurements and enhance our underst…
