Responses of Halo Occupation Distributions: a new ingredient in the halo model & the impact on galaxy bias
Rodrigo Voivodic, Alexandre Barreira
Halo occupation distribution (HOD) models describe the number of galaxies that reside in different haloes, and are widely used in galaxy-halo connection studies using the halo mode…
The Effective Field Theory and Perturbative Analysis for Log-Density Fields
Henrique Rubira, Rodrigo Voivodic
A logarithm transformation over the matter overdensity field brings information from the bispectrum and higher-order n-point functions to the power spectrum. We calculate the p…
Excursion Set Halos -- ExSHalos: A New Parameter Free Method for Fast Generation of Halo Catalogues
Rodrigo Voivodic, Marcos Lima, Luis Raul Abramo
We develop a new, simple, fast and parameter-free method to construct dark matter halo catalogues. This method requires as inputs only the linear matter power spectrum and the thre…
Cosmic voids in modified gravity scenarios
E L D Perico, R Voivodic, M Lima +1
Modified gravity (MG) theories aim to reproduce the observed acceleration of the Universe by reducing the dark sector while simultaneously recovering General Relativity (GR) within…
Relation between the Turnaround radius and virial mass in model
Rafael C. C. Lopes, Rodrigo Voivodic, L. Raul Abramo +1
We investigate the relationship between the turnaround radius () and the virial mass () of cosmic structures in the context of CDM model and in an model of modi…
Turnaround radius in model
Rafael C. C. Lopes, Rodrigo Voivodic, Luis Raul Abramo +1
We investigate the turnaround radius in the spherical collapse model, both in General Relativity and in modified gravity, in particular scenarios. The phases of spherical co…
