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…

Two new tests to the distance duality relation with galaxy clusters

S. Santos-da-Costa, V. C. Busti, R. F. L. Holanda

The cosmic distance duality relation is a milestone of cosmology involving the luminosity and angular diameter distances. Any departure of the relation points to new physics or sys…
