Probing the cosmic distance duality with strong gravitational lensing and supernovae Ia data

R. F. L. Holanda, V. C. Busti, J. S. Alcaniz

We propose and perform a new test of the cosmic distance-duality relation (CDDR), $D_{L} (z) / D_{A} (z) (1 + z)^{2} = 1$ , where $D_{A}$ is the angular diameter distance and $D_{L}$ is the l…

Constraints on a possible variation of the fine structure constant from galaxy cluster data

R. F. L. Holanda, S. J. Landau, J. S. Alcaniz +2

We propose a new method to probe a possible time evolution of the fine structure constant $α$ from X-ray and Sunyaev-Zeldovich measurements of the gas mass fraction ( $f_{g a s}$ ) in…

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 $H_{0}$ and $q_{0}$ through the celestial sphere. In our analysis, performed in a low-r…
