The atacama cosmology telescope: cosmological parameters from three seasons of data.
(Journal of Cosmology and Astroparticle Physics, 2013)
Dynamics and constraints of the massive graviton dark matter flat cosmologies
(AMER PHYSICAL SOC, 2011)
We discuss the dynamics of the Universe within the framework of the massive graviton cold dark matter scenario (MGCDM) in which gravitons are geometrically treated as massive particles. In this modified gravity theory, the ...
Galaxy clusters, type Ia supernovae and the fine structure constant
(IOP Publishing, 2016-08)
As is well known, measurements of the Sunyaev-Zeldovich effect can be combined with observations of the X-ray surface brightness of galaxy clusters to estimate the angular diameter distance to these structures. In this ...
Submillimeter galaxies behind the Bullet cluster (1E 0657-56)
(2010)
Context. Clusters of galaxies are effective gravitational lenses able to magnify background galaxies and making it possible to probe the fainter part of the galaxy population. Submillimeter galaxies, which are believed to ...
Cosmic distance duality relation and the shape of galaxy clusters
(EDP SCIENCES S A, 2011)
Context. Observations in the cosmological domain are heavily dependent on the validity of the cosmic distance-duality (DD) relation, eta = D(L)(z)(1+ z)(2)/D(A)(z) = 1, an exact result required by the Etherington reciprocity ...
TESTING THE DISTANCE-DUALITY RELATION WITH GALAXY CLUSTERS AND TYPE Ia SUPERNOVAE
(IOP PUBLISHING LTD, 2010)
In this Letter, we propose a new and model-independent cosmological test for the distance-duality (DD) relation, eta = D(L)(z)(1 + z)(-2)/D(A)(z) = 1, where D(L) and D(A) are, respectively, the luminosity and angular ...
