Radio galaxy populations and the multitracer technique: pushing the limits on primordial non-Gaussianity
We explore the use of different radio galaxy populations as tracers of different mass haloes and therefore, with different bias properties, to constrain primordial non-Gaussianity of the local type.We perform a Fisher matrix analysis based on the predicted auto- and cross-angular power spectra of th...
