Dark energy and cosmic acceleration
Rodrigo von Marttens, Jailson Alcaniz
The discovery that we live in an accelerating universe changed drastically the paradigm of physics and introduced the concept of \textit{dark energy}. In this work, we present a br…
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-Antolínez, 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…
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…
Inferring galaxy dark halo properties from visible matter with Machine Learning
Rodrigo von Marttens, Luciano Casarini, Nicola R. Napolitano +6
Next-generation surveys will provide photometric and spectroscopic data of millions to billions of galaxies with unprecedented precision. This offers a unique chance to improve our…
Dark degeneracy I: Dynamical or interacting dark energy?
Rodrigo von Marttens, Lucas Lombriser, Martin Kunz +3
We revisit the dark degeneracy that arises from the Einstein equations relating geometry to the total cosmic substratum but not resolving its individual components separately. We e…
Degeneracy between nonadiabatic dark energy models and CDM: ISW effect and the cross correlation of CMB with galaxy clustering data
Hermano Velten, Raquel Emy Fazolo, Rodrigo von Marttens +1
As recently pointed out in Ref. [Phys.\ Rev.\ D {\bf 96}, 8, 083502 (2017)] the evolution of the linear matter perturbations in nonadiabatic dynamical dark energy models is almost…
