Optimal constraints on Primordial non-Gaussianity with the eBOSS DR16 quasars in Fourier space

Marina S. Cagliari, Emanuele Castorina, Marco Bonici +1

We present constraints on the amplitude of local Primordial Non-Gaussianities (PNG), $f_{\mathrm{NL}}$, using the quasar sample in the Sloan Digital Sky Survey IV extended Baryon Oscill…
