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 . We present the methodology to meas…

Validating galaxy clustering models with Fixed & Paired and Matched-ICs simulations: application to Primordial Non-Gaussianities
Santiago Avila, Adrian G. Adame
The Fix and Pair techniques were designed to generate simulations with reduced variance in the 2-point statistics by modifying the Initial Conditions (ICs). In this paper we show t…
