Inhomogeneus Inflation and Cosmic no-Hair Conjecture
M. A. S. Nobre, M. R. de Garcia Maia, J. C. Carvalho +1
The cosmic no hair conjecture is tested for a large class of inhomogeneous cosmologies with a positive cosmological constant. Firstly, we derive a new class of exact inhomogeneous…
Power-law statistics and stellar rotational velocities in the Pleiades
J. C. Carvalho, R. Silva, J. D. Jr. do Nascimento +1
In this paper we will show that, the non-gaussian statistics framework based on the Kaniadakis statistics is more appropriate to fit the observed distributions of projected rotatio…
Comparison of Radio Observations and Numerical Simulations of the Radio Lobes of Cygnus A
J. C. Carvalho, R. A. Daly, M. P. Mory +1
We present a comparison of radio observations of the archetypal powerful radio galaxy Cygnus A and 2-D numerical hydrodynamical simulations. We characterize some global trends in t…
Nonsingular FRW cosmology and nonlinear electrodynamics
C. S. Camara, M. R. de Garcia Maia, J. C. Carvalho +1
The possibility to avoid the cosmic initial singularity as a consequence of nonlinear effects on the Maxwell eletromagnetic theory is discussed. For a flat FRW geometry we derive t…
