The baryon mass function for galaxy clusters
(Edp Sciences, 2006-06)
Context.The evolution of the cluster abundance with redshift is known to be a powerful cosmological constraint when applied to X-ray clusters. Recently, the evolution of the baryon mass function has been proposed as a new ...
Testing extended Jordan-Brans-Dicke theories with future cosmological observations
(Institute of Physics Publishing, 2019)
© 2019 IOP Publishing Ltd and Sissa Medialab.The extended Jordan-Brans-Dicke (eJBD) theory of gravity is constrained by a host of astrophysical and cosmological observations spanning a wide range of scales. The current ...
Observational constraints on holographic tachyonic dark energy in interaction with dark matter
(IOP PUBLISHING LTD, 2010)
We discuss an interacting tachyonic dark energy model in the context of the holographic principle. The potential of the holographic tachyon field in interaction with dark matter is constructed. The model results are compared ...
Influence of small-scale inhomogeneities on the cosmological consistency tests
(WILEY-BLACKWELLHOBOKEN, 2012)
The current cosmological dark sector (dark matter plus dark energy) is challenging our comprehension about the physical processes taking place in the Universe. Recently, some authors tried to falsify the basic underlying ...
Can varying the gravitational constant alleviate the tensions?
(IOP, 2022)
Constraints on the cosmological concordance model parameters from observables at different redshifts are usually obtained using the locally measured value of the gravitational constant G(N). Here we relax this assumption, ...
Cosmological parameter analyses using transversal BAO data
(2020-09-01)
We investigate observational constraints on cosmological parameters combining 15 measurements of the transversal BAO scale (obtained free of any fiducial cosmology) with Planck-CMB data to explore the parametric space of ...
