Constraining primordial non-Gaussianity from DESI DR1 quasars and Planck PR4 CMB Lensing
Sofia Chiarenza, Alex Krolewski, Marco Bonici +54
We present the first measurement of local-type primordial non-Gaussianity from the cross-correlation between million spectroscopically confirmed quasars from the first data r…
