Determinación de la constante de Hubble mediante observaciones del Universo Local
(Real Sociedad Española de Física, 2020-04)En este trabajo se ofrece el resultado de una determinación directa de la constante de Hubble H0 a partir de observaciones del Universo Local. Para ello hemos usado la técnica de la escalera cósmica de distancias siguiendo ... -
BAO cosmology in non-spatially flat background geometry from BOSS+eBOSS and lessons for future surveys
(IOP Publishing, 2024)We study the impact of the assumption of a non-flat fiducial cosmology on the measurement, analysis and interpretation of BAO distance variables, along and across the line-of-sight. The assumption about cosmology enters ... -
Evidence for baryon acoustic oscillations from galaxy–ellipticity correlations
(Springer, 2023)The Baryon Acoustic Oscillations (BAO) feature in the clustering of galaxies or quasars provides a "standard ruler" for distance measurements in cosmology. In this work, we report a 2∼3σ signal of the BAO dip feature in ... -
Photon to axion conversion during Big Bang Nucleosynthesis
(IOP Publishing, 2023)We investigate how the resonant conversion at a temperature T¯=25-65 keV of a fraction of the CMB photons into an axion-like majoron affects BBN. The scenario, that assumes the presence of a primordial magnetic field and ... -
Cosmology of an axion-like majoron
(IOP Publishing, 2022)We propose a singlet majoron model that defines an inverse seesaw mechanism in the ν sector. The majoron ϕ has a mass mϕ ≈ 0.5 eV and a coupling to the τ lepton similar to the one to neutrinos. In the early universe it is ...
