The Hubble constant tension with next-generation galaxy surveys
Carlos A. P. Bengaly, Chris Clarkson, Roy Maartens
The rate at which the universe is expanding today is a fundamental parameter in cosmology which governs our understanding of structure formation and dark energy. However, current m…
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…
Isotropy of low redshift type Ia Supernovae: A Bayesian analysis
U. Andrade, C. A. P. Bengaly, J. S. Alcaniz +1
The standard cosmology strongly relies upon the Cosmological Principle, which consists on the hypotheses of large scale isotropy and homogeneity of the Universe. Testing these assu…
Probing the Cosmological Principle in the counts of radio galaxies at different frequencies
C. A. P. Bengaly, R. Maartens, M. G. Santos
According to the Cosmological Principle, the matter distribution on very large scales should have a kinematic dipole that is aligned with that of the CMB. We determine the dipole a…
Constraining cosmic isotropy with type Ia supernovae
C. A. P. Bengaly, A. Bernui, J. S. Alcaniz
We investigate the validity of the Cosmological Principle by constraining the cosmological parameters and through the celestial sphere. Our analyses are performed in a…
Probing Cosmological Isotropy With Type IA Supernovae
C. A. P. Bengaly, A. Bernui, J. S. Alcaniz
We investigate the validity of the Cosmological Principle by mapping the cosmological parameters and through the celestial sphere. In our analysis, performed in a low-r…
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…
Forecasting cosmological constraints from age of high-z galaxies
C. A. P. Bengaly, M. A. Dantas, J. C. Carvalho +1
We perform Monte Carlo simulations based on current age estimates of high-z objects to forecast constraints on the equation of state (EoS) of the dark energy. In our analysis, we u…
