Standard Perturbation Theory for Interacting Dark Sector cosmologies I: Breakdown of Einstein de Sitter kernels
Matheus Wolney, Gabriel Sampaio, Humberto Borges +2
Interacting dark sector (IDS) models provide a commonly explored extension of the standard CDM cosmology, allowing for non-gravitational energy--momentum exchange between cold…
Dark Degeneracy in DESI DR2: Interacting or Evolving Dark Energy?
Vitor Petri, Valerio Marra, Rodrigo von Marttens
The standard CDM model, despite its success, is challenged by persistent observational tensions in the Hubble constant () and the matter clustering amplitude (), moti…
Total and dark mass from observations of galaxy centers with Machine Learning
Sirui Wu, Nicola R. Napolitano, Crescenzo Tortora +4
The galaxy total mass inside the effective radius encode important information on the dark matter and galaxy evolution model. Total "central" masses can be inferred via galaxy dyna…
The matter with(in) CPL
Leonardo Giani, Rodrigo Von Marttens, Oliver Fabio Piattella
We introduce a two-parameter phenomenological extension of the CDM model in which the equation of state parameter of the ``dust'' fluid becomes different from zero for redshift…
The J-PLUS collaboration. Additive versus multiplicative systematics in surveys of the large scale structure of the Universe
C. Hernández-Monteagudo, G. Aricò, J. Chaves-Montero +19
Observational and/or astrophysical systematics modulating the observed number of luminous tracers can constitute a major limitation in the cosmological exploitation of surveys of t…
J-PLUS: Tomographic analysis of galaxy angular density and redshift fluctuations in Data Release 3. Constraints on photo- errors, linear bias, and peculiar velocities
C. Hernández-Monteagudo, A. Balaguera-AntolÃnez, R. von Marttens +19
The {\it Javalambre Photometric Local Universe Survey} (J-PLUS) is a {\it spectro-photometric} survey covering about 3,000~deg in its third data release (DR3), and containing a…
