Searching for deviations from the General Relativity Theory with gas mass fraction of galaxy clusters and complementary probes
R. F. L. Holanda, S. H. Pereira, S. Santos-da-Costa
Nowadays, thanks to the improved precision of cosmological data, it has been possible to search for deviation from the general relativity theory with tests on large cosmic scales.…
Probing the distance-duality relation with high- data
R. F. L. Holanda, V. C. Busti, F. S. Lima +1
Measurements of strong gravitational lensing jointly with type Ia supernovae (SNe Ia) observations have been used to test the validity of the cosmic distance duality relation (CDDR…
Can galaxy clusters, type Ia supernovae and cosmic microwave background rule out a class of modified gravity theories?
R. F. L. Holanda, S. H. Pereira
In this paper we study cosmological signatures of modified gravity theories that can be written as a coupling between a extra scalar field and the electromagnetic part of the usual…
Searching for cosmological signatures of the Einstein equivalence principle breaking
R. F. L. Holanda, K. N. N. O. Barros
Modifications of gravity generated by a multiplicative coupling of a scalar field to the electromagnetic Lagrangian lead to a breaking of Einstein equivalence principle (EEPB) as w…
A generalized Neyman-Pearson lemma for sublinear expectations
Chuanfeng Sun, Shaolin Ji
In this paper, the Neyman-Pearson lemma for general sublinear expectations is studied. We weaken the assumptions for sublinear expectations in [1] and give a completely new method…
Galaxy clusters, type Ia supernovae and the fine structure constant
R. F. L. Holanda, V. C. Busti, L. R. Colaço +2
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…
