Abstract:
We present constraints on the amplitude of local Primordial Non-Gaussianities
(PNG), $f_{\rm NL}$, using the quasar sample in the Sloan Digital Sky Survey IV
extended Baryon Oscillation Spectroscopic Survey Data Release 16. We analyze
the power spectrum monopole, testing for the presence of scale dependent galaxy
bias induced by local PNG. Our analysis makes use of optimal redshift weights
that maximize the response of the quasar sample to the possible presence of non
zero PNG. We find $-4
