Primordial non-Gaussianity with Angular correlation function: Integral constraint and validation for DES

Walter Riquelme, Santiago Avila, Juan Garcia-Bellido +17

Local primordial non-Gaussianity (PNG) is a promising observable of the underlying physics of inflation, characterised by $f_{\mathrm{NL}}^{\mathrm{loc}}$. We present the methodology to meas…
