Assembly bias and local Primordial non-Gaussianity from DESI DR1 Quasars
E. Fondi, L. Verde, E. Chaussidon +40
The analysis of the large-scale clustering of quasars (QSO) observed by the Dark Energy Spectroscopic Instrument (DESI) represents a promising avenue for constraining local Primord…

: Accurate non-Gaussian initial conditions with arbitrary bispectrum for N-body simulations
Emanuele Fondi, Licia Verde, Marco Baldi +3
Primordial non-Gaussianity is predicted by various inflationary models, and N-body simulations are a crucial tool for studying its imprints on large-scale structure. In this work,…

Wonderings on Wiggly Bispectra: Non-linear Evolution and Reconstruction of Oscillations in the Squeezed Bispectrum
Samuel Goldstein, Oliver H. E. Philcox, Emanuele Fondi +1
Oscillations in the primordial bispectrum are sourced by a range of inflationary phenomena, including features in the inflaton potential and interactions with massive fields throug…
