On the range of validity of perturbative models for galaxy clustering and its uncertainty
Giosuè Gambardella, Matteo Biagetti, Chiara Moretti +1
We explore the reach of analytical models at one-loop in Perturbation Theory (PT) to accurately describe measurements of the galaxy power spectrum from numerical simulations in red…
