Entropic gravity from noncommutative black holes
Rafael C. Nunes, Hooman Moradpour, Edésio M. Barboza +2
In this paper we will investigate the effects of a noncommutative (NC) space-time on the dynamics of the universe. We will generalize the black hole entropy formula for a NC black…

Testing the cosmic conservation of photon number with type Ia supernovae and ages of old objects
J. F. Jesus, R. F. L. Holanda, M. A. Dantas
In this paper, we obtain luminosity distances by using ages of 32 old passive galaxies distributed over the redshift interval and test the cosmic conservation of…

Jeans instability criterion from the viewpoint of non-gaussian statistics
Everton M. C. Abreu, Jorge Ananias Neto, Edesio M. Barboza +1
In this Letter we have derived the Jeans length in the context of the Kaniadakis statistics. We have compared this result with the Jeans length obtained in the non-extensive Tsalli…
