The Twentieth Data Release of the Sloan Digital Sky Survey: First All-Sky BOSS Spectra, eROSITA-SDSS-V Mapper Coordinated Observations, and a Preview of the Local Volume Mapper
SDSS Collaboration, Mojgan Aghakhanloo, David Aguilar +273
This paper presents the twentieth data release (DR20) from the Sloan Digital Sky Survey, the third data release of its fifth generation (SDSS-V). SDSS-V is a panoptic spectroscopy…
Preliminary cosmological results using extreme accretors Quasar formalism
Rodrigo Sandoval-Orozco, Castalia Alenka Negrete, Paola Marziani +1
We revisited the xA Quasar formalism from the cosmological point of view, where a completely cleaned and standardized sample is compiled from different literature references. This…
SDSS-V Black Hole Mapper: The Index Diagram as a tool to disentangle the influence of the Host Galaxy in Quasar spectra
C. A. Negrete, R. Sandoval-Orozco, H. Ibarra-Medel +32
We revisit the Quasar Main Sequence (QMS) by investigating the impact of the stellar component from the host galaxy (HG) on the emission line spectra of the active galactic nuclei…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
gravity after DESI Baryon Acoustic Oscillation and DES Supernovae 2024 data
Celia Escamilla-Rivera, Rodrigo Sandoval-Orozco
In this work, we investigate new constraints on gravity using the recent Baryon Acoustic Oscillation (BAO) data released by the Dark Energy Spectroscopic Instrument (DESI) a…
Testing cosmologies with HII Hubble diagram and CMB distance priors
Rodrigo Sandoval-Orozco, Celia Escamilla-Rivera, Rebecca Briffa +1
In this work, we present independent determinations of cosmological parameters and new constraints on cosmologies, employing two new catalogs related to HII galaxy Hubble an…
