From Dark Radiation to Dark Energy: Unified Cosmological Evolution in K-essence Models
Eladio Moreno, Josue De-Santiago
We study a class of Unified Dark Matter (UDM) models based on generalized K-essence, where a single scalar field with non-canonical kinetic terms accounts for dark radiation, dark…
Lya2pcf: an efficient pipeline to estimate two- and three-point correlation functions of the Lyman- forest
Josue De-Santiago, Rafael Gutiérrez-Balboa, Gustavo Niz +1
Studying the matter distribution in the universe through the Lyman- forest allows us to constrain small-scale physics in the high-redshift regime. Spectroscopic quasar surveys a…
Resonant neutrino self-interactions: Insights from the full shape galaxy power spectrum
Hernán E. Noriega, Josue De-Santiago, Gabriela Garcia-Arroyo +2
This paper investigates resonant neutrino self-interactions in cosmology by employing, for the first time, the effective field theory of large-scale structure to model their impact…
Redshift Assessment Infrastructure Layers (RAIL): Rubin-era photometric redshift stress-testing and at-scale production
The RAIL Team, Jan Luca van den Busch, Eric Charles +31
Virtually all extragalactic use cases of the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) require the use of galaxy redshift information, yet the vast majorit…
