Fullshape power spectrum for the Symmetron modified gravity model
Gerardo Morales-Navarrete, Jorge L. Cervantes-Cota
We make use of the perturbation theory for modified gravity models that we developed in previous works and apply it to construct the fullshape galaxy power spectrum for the Symmetr…
Remembering George Smoot
John Berliner, Tom Broadhurst, Martin Bucher +31
George Smoot (1945-2025) was a major figure in observational cosmology, particularly through his role in the precision measurement of the CMB dipole and the discovery of the primor…
Dark energy from neutrino interactions in Unimodular Gravity
Alejandro Gil-Ocaranza, Josue De-Santiago, Mauricio Lopez-Hernandez +1
We investigate a dark energy scenario generated by neutrino interactions mediated by a light scalar field, in which finite-temperature corrections induce an effective neutrino mass…
Negative Masses and Spatial Curvature: Alleviating Neutrino Mass Tensions in LambdaCDM and Extended Cosmologies
Hayyim Pulido-Hernández, Jorge L. Cervantes-Cota
We investigate the impact of spatial curvature, , and dynamical dark energy on the cosmological constraints of the neutrino mass sum, . Using a joint analysis of t…
Data Release 1 of the Dark Energy Spectroscopic Instrument
DESI Collaboration, M. Abdul Karim, A. G. Adame +306
In 2021 May the Dark Energy Spectroscopic Instrument (DESI) collaboration began a 5-year spectroscopic redshift survey to produce a detailed map of the evolving three-dimensional s…
Effects of Symmetron on growth and RSD multipoles
Gerardo Morales-Navarrete, Jorge L. Cervantes-Cota
In this work, we investigate the effects of the growth rate scale dependence in the Symmetron modified gravity (MG) model on cosmic structure formation and we analyze the redshift-…
