Cosmography with DESI-DR1 Cosmic Chronometers: Direct H(z) measurements from Luminous Red Galaxy ages
Carlos A. Álvarez, Marcos M. Cueli, Balakrishna S. Haridasu +6
Providing robust redshift estimates for almost 3 million luminous red galaxies (LRGs), the Dark Energy Spectroscopic Instrument (DESI) offers a unique opportunity to test the expan…
Cosmography via stellar archaeology of low-redshift early-type galaxies from SDSS
Carlos A. Ãlvarez, Marcos M. Cueli, Alessandro Bressan +5
Cosmic chronometers offer a model-independent way to trace the expansion history of the Universe via the dating of passively evolving objects. This enables testing the validity of…
Weighing neutrinos with 21cm Intensity Mapping at the SKAO
Gabriele Autieri, Maria Berti, Marta Spinelli +2
We explore the constraining power of future 21cm intensity mapping (IM) observations at the SKAO, focusing primarily on the sum of neutrino masses, . We forecast observatio…
Little ado about everything II: an `emergent' dark energy from structure formation to rule cosmic tensions
Andrea Lapi, Balakrishna S. Haridasu, Lumen Boco +3
[abridged] The CDM framework is a new cosmological model aimed to cure some drawbacks of the standard CDM scenario, such as the origin of the accelerated expansion at late…
A Relativistic Tensorial Model for Fractional Interaction between Dark Matter and Gravity
Francesco Benetti, Andrea Lapi, Samuele Silveravalle +5
In a series of recent papers it was shown that several aspects of Dark Matter (DM) phenomenology, such as the velocity profiles of individual dwarfs and spiral galaxies, the scalin…
