DESCRIPTION:Speakers: Adrián Gutiérrez Adame (UAM - IFT)\nIn this presen
 tation I will talk about  the PNG-UNITsims suite\, which includes the la
 rgest full N-body simulation to date with local primordial non-Gaussianiti
 es (local PNG)\, the PNG-UNIT. The amplitude of the PNGs is given by fNL
 l⁢o⁢c⁢a⁢l=100. The simulation follows the evolution of 4096^3 pa
 rticles in a periodic box with Lbox=1⁢h^−1⁢Gpc\, resulting in a mas
 s resolution of mp=1.24×10^9⁢h^−1⁢M⊙\, enough to finely resolve 
 the galaxies targeted by stage-IV spectroscopic surveys. The PNG-UNIT ha
 s fixed initial conditions with phases also matching the pre-existing UNI
 T simulation with Gaussian initial conditions. The fixed and matched init
 ial conditions reduce the simulation uncertainty significantly. In this fi
 rst study of the PNG-UNITsims\, we measure the PNG response parameter\, 
 p\, as a function of the halo mass. halos with masses between 1×10^12 a
 nd 5×10^13⁢h^−1⁢M⊙ are well described by the universality relat
 ion\, given by p=1. For halos with masses between 2×10^10 and 1×10^1
 2⁢h^−1⁢M⊙ we find that p\n\nhttps://indico.ific.uv.es/event/7664
