Field-level inference of growth rate from DESI BGS galaxy and ZTF supernova simulations
Corentin Ravoux, Bastien Carreres, Julian Bautista +60
Galaxy peculiar velocities are a powerful probe of the growth rate of structure at low redshifts (), measured through the combination . These constraints are imp…
Can the angular scale of cosmic homogeneity be used as a cosmological test?
Xiaoyun Shao, Rodrigo S. Gonçalves, Carlos A. P. Bengaly +3
In standard cosmology, the cosmic homogeneity scale is the transition scale above which the patterns arising from non-uniformities -- such as groups and clusters of galaxies, voids…
The angular scale of homogeneity with SDSS-IV DR16 Luminous Red Galaxies
Uendert Andrade, Rodrigo S. Gonçalves, Gabriela C. Carvalho +3
We report measurements of the angular scale of cosmic homogeneity () using the recently released luminous red galaxy sample of the sixteenth data release of the Sloan Digita…
A Test of the Standard Cosmological Model with Geometry and Growth
Uendert Andrade, Dhayaa Anbajagane, Rodrigo von Marttens +2
We perform a general test of the and cosmological models by comparing constraints on the geometry of the expansion history to those on the growth of stru…
Measuring the cosmic homogeneity scale with SDSS-IV DR16 Quasars
Rodrigo S. Gonçalves, Gabriela C. Carvalho, Uendert Andrade +3
We report measurements of the scale of cosmic homogeneity () using the recently released quasar sample of the sixteenth data release of the Sloan Digital Sky Survey (SDSS-IV…
The miniJPAS survey: a preview of the Universe in 56 colours
S. Bonoli, A. Marín-Franch, J. Varela +166
The Javalambre-Physics of the Accelerating Universe Astrophysical Survey (J-PAS) will soon start to scan thousands of square degrees of the northern extragalactic sky with a unique…
Revisiting the statistical isotropy of GRB sky distribution
Uendert Andrade, Carlos A. P. Bengaly, Jailson S. Alcaniz +1
The assumption of homogeneity and isotropy on large scales is one of the main hypotheses of the standard cosmology. In this paper, we test the hypothesis of isotropy from the two-p…
How does an incomplete sky coverage affect the Hubble Constant variance?
Carlos A. P. Bengaly, Uendert Andrade, Jailson S. Alcaniz
We address the tension between local and the CMB measurements of the Hubble Constant using simulated Type Ia Supernova (SN) data-sets. We probe its directional depend…
A Model-independent Test of Cosmic Isotropy with Low-z Pantheon Supernovae
Uendert Andrade, Carlos A. P. Bengaly, Beethoven Santos +1
The assumption of homogeneity and isotropy on large scales is one of the main hypotheses of the standard cosmological model. In this paper, we revisit a test of cosmological isotro…
