Cosmic adiabatic photon creation: Temperature law and blackbody spectrum
J. A. S. Lima, S. R. G. Trevisani, R. C. Santos
The temperature-redshift relation (cosmic thermometer) is rediscussed in the framework of gravitationally induced photon production in the expanding universe. It is found that the…
From Solar Eclipse of 1919 to the Spectacle of Gravitational Lensing
J. A. S. Lima, R. C. Santos
A century after observing the deflection of light emitted by distant stars during the solar eclipse of 1919, it is interesting to know the concepts emerged from the experiment and…
100 Years of Relativistic Cosmology (1917-2017). Part I: From Origins to the Discovery of Universal Expansion (1929)
J. A. S. Lima, R. C. Santos
We are experiencing a period of extreme intellectual effervescence in the area of cosmology. A huge volume of observational data in unprecedented quantity and quality and a more co…
Is CDM an effective CCDM cosmology?
J. A. S. Lima, R. C. Santos, J. V. Cunha
We show that a cosmology driven by gravitationally induced particle production of all non-relativistic species existing in the present Universe mimics exactly the observed flat acc…
From de Sitter to de Sitter: decaying vacuum models as a possible solution to the main cosmological problems
G. J. M. Zilioti, R. C. Santos, J. A. S. Lima
Decaying vacuum cosmological models evolving smoothly between two extreme (very early and late time) de Sitter phases are capable to solve or at least to alleviate some cosmologica…
A note on linearized "New Massive Gravity" in arbitrary dimensions
D. Dalmazi, R. C. Santos
By means of a triple master action we deduce here a linearized version of the "New Massive Gravity" (NMG) in arbitrary dimensions. The theory contains a 4th-order and a 2nd-order t…
