Accurate -body simulations with local Primordial non-Gaussianities: initial conditions and aliasing

Adrian G. Adame, Santiago Avila, Violeta Gonzalez-Perez +3

New generation galaxy surveys targeting constraints on local primordial non-Gaussianity (PNG) demand -body simulations that accurately reproduce its effects. In this work, we ex…

The multi-dimensional halo assembly bias can be preserved when enhancing halo properties with HALOSCOPE

Sujatha Ramakrishnan, Violeta Gonzalez-Perez, Gabriele Parimbelli +1

Over \% of dark matter haloes in cosmological simulations have unresolved properties. This can hinder the dynamical range of simulations and result in systematic biases when mo…

An improved Halo Occupation Distribution prescription from UNITsim H_alpha Emission Line Galaxies: conformity and modified radial profile

Guillermo Reyes-Peraza, Santiago Avila, Violeta Gonzalez-Perez +4

Emission line galaxies (ELGs) are targeted by the new generation of spectroscopic surveys to make unprecedented measurements in cosmology from their distribution. Accurately interp…

Improving and extending non-Poissonian distributions for satellite galaxies sampling in HOD: applications to eBOSS ELGs

Bernhard Vos-Ginés, Santiago Avila, Violeta Gonzalez-Perez +1

Halo Occupation Distribution (HOD) models help us to connect observations and theory, by assigning galaxies to dark matter haloes. In this work we study one of the components of HO…
