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…
On the impact of galaxy bias uncertainties on primordial non-Gaussianity constraints
Alexandre Barreira
We study the impact that uncertainties on assumed relations between galaxy bias parameters have on constraints of the local PNG parameter. We focus on the relation bet…
Galaxy bias and primordial non-Gaussianity: insights from galaxy formation simulations with IllustrisTNG
Alexandre Barreira, Giovanni Cabass, Fabian Schmidt +2
We study the impact that large-scale perturbations of (i) the matter density and (ii) the primordial gravitational potential with local primordial non-Gaussianity (PNG) have on gal…
Compensated Isocurvature Perturbations in the Galaxy Power Spectrum
Alexandre Barreira, Giovanni Cabass, Kaloian D. Lozanov +1
We investigate the potential of the galaxy power spectrum to constrain compensated isocurvature perturbations (CIPs), primordial fluctuations in the baryon density that are compens…
