Cosmic homogeneity: the effect of redshift-space distortions and bias and cosmological constraints
Xiaoyun Shao, Rodrigo Gonçalves, Carlos A. P. Bengaly +2
We present a novel cosmological analysis based on the angular correlation dimension curve, a cumulative statistic derived from the two-point correlation function. Unlike trad…
Cosmological constraints from angular homogeneity scale measurements
Xiaoyun Shao, Carlos A. P. Bengaly, Rodrigo S. Gonçalves +2
In this paper, we obtain new measurements of the angular homogeneity scale () from the BOSS DR12 and eBOSS DR16 catalogs of Luminous Red Galaxies of the Sloan Digital Sky Surv…
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…
Formation and Evolution of Wakes in the Spacetime Generated by a Cosmic String in Theory of Gravity
G. C. Carvalho, M. E. X. Guimarães, P. O. Mesquita +1
The formation and evolution of cosmic string wakes in the framework of a theory of gravity are investigated in this work. We consider a simple model in which baryonic matter…
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…
Measuring the scale of cosmic homogeneity with SDSS-IV DR14 quasars
R. S. Gonçalves, G. C. Carvalho, C. A. P. Bengaly +2
The quasar sample of the fourteenth data release of the Sloan Digital Sky Survey (SDSS-IV DR14) is used to determine the cosmic homogeneity scale in the redshift range $0.80<z<2.24…
Cosmic homogeneity: a spectroscopic and model-independent measurement
R. S. Gonçalves, G. C. Carvalho, C. A. P. Bengaly +4
Cosmology relies on the Cosmological Principle, i.e., the hypothesis that the Universe is homogeneous and isotropic on large scales. This implies in particular that the counts of g…
Measuring the transverse baryonic acoustic scale from the SDSS DR11 galaxies
G. C. Carvalho, A. Bernui, M. Benetti +3
We report five measurements of the transverse baryonic acoustic scale, , obtained from the angular two-point correlation function calculation for Luminous Red Galaxies of…
Angular Baryon Acoustic Oscillation measure at z=2.225 from the SDSS quasar survey
E. de Carvalho, A. Bernui, G. C. Carvalho +2
Following a quasi model-independent approach we measure the transversal BAO mode at high redshift using the two-point angular correlation function (2PACF). The analyses done here a…
Measuring baryon acoustic oscillations with angular two-point correlation function
Jailson S. Alcaniz, Gabriela C. Carvalho, Armando Bernui +2
The Baryon Acoustic Oscillations (BAO) imprinted a characteristic correlation length in the large-scale structure of the universe that can be used as a standard ruler for mapping o…
A low- test for interacting dark energy
R. S. Goncalves, G. C. Carvalho, J. S. Alcaniz
A non-minimal coupling between the dark matter and dark energy components may offer a way of solving the so-called coincidence problem. In this paper we propose a low- test for…
Baryon Acoustic Oscillations from the SDSS DR10 galaxies angular correlation function
G. C. Carvalho, A. Bernui, M. Benetti +2
The 2-point angular correlation function (2PACF), where is the angular separation between pairs of galaxies, provides the transversal Baryon Acoustic Oscillation (BAO) s…
J-PAS: The Javalambre-Physics of the Accelerated Universe Astrophysical Survey
N. Benitez, R. Dupke, M. Moles +149
The Javalambre-Physics of the Accelerated Universe Astrophysical Survey (J-PAS) is a narrow band, very wide field Cosmological Survey to be carried out from the Javalambre Observat…
