D. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    We describe and test the fiducial covariance matrix model for the combined two-point function analysis of the Dark Energy Survey Year 3 (DES-Y3) data set. Using a variety of new ansatzes for covariance modelling and testing, ...

    ABSTRACT We perform an analysis in harmonic space of the Dark Energy Survey Year 1 Data (DES-Y1) galaxy clustering photometric data using products obtained for the real-space analysis. We test our pipeline with ...

    Riquelme, Walter; Avila, Santiago; García-Bellido, Juan; Porredon, Anna; Ferrero, Ismael; Chan, Kwan Chuen; Rosenfeld, Rogerio; Camacho, Hugo; Adame, Adrian G.; Carnero Rosell, Aurelio; Crocce, Martin; De Vicente, Juan; Eifler, Tim; Elvin-Pool, Jack; Fang, Xiao; Krause, Elisabeth; Rodriguez Monroy, Martin; Ross, Ashley J.; Sanchez, Eusebio; Sevilla, Ignacio (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Local primordial non-Gaussianity (PNG) is a promising observable of the underlying physics of inflation, characterized by flocNL⁠. We present the methodology to measure flocNL from the Dark Energy Survey (DES) data using ...
