Forecasting local Primordial Non-Gaussianities from UNIONS Lyman-Break Galaxies and Planck CMB lensing
Constantin Payerne, William d'Assignies, Christophe Yèche +4
Local Primordial non-Gaussianities (PNGs), characterized by , provide a powerful window into the physics of inflation. Cross-correlating high-redshift tracer…

Selection of high-redshift Lyman-Break Galaxies from broadband and wide photometric surveys
C. Payerne, W. d'Assignies Doumerg, C. Yèche +44
In this paper, we investigate the possibility of selecting high-redshift Lyman-Break Galaxies (LBG) using current and future broadband wide photometric surveys, such as UNIONS or t…
