Probing Yukawian Gravitational Potential by Numerical Simulations. II. Elliptical Galaxies
C. S. S. Brandao, J. C. N. de Araujo
Since the Newtonian gravitation is largely used to model with success the structures of the universe, such as galaxies and clusters of galaxies, for example, a way to probe and con…
Gravitational wave background from neutron star phase transition for a new class of equation of state
J. C. N. de Araujo, G. F. Marranghello
We study the generation of a stochastic gravitational wave (GW) background produced by a population of neutron stars (NSs) which go over a hadron-quark phase transition in its inne…
Probing Yukawian gravitational potential by numerical simulations. I. Changing N-body codes
C. S. S. Brandao, J. C. N. de Araujo
In the weak field limit general relativity reduces, as is well known, to the Newtonian gravitation. Alternative theories of gravity, however, do not necessarily reduce to Newtonian…
Probing the f(R) formalism through gravitational wave polarizations
Marcio E. S. Alves, Oswaldo D. Miranda, Jose C. N. de Araujo
The direct observation of gravitational waves (GWs) in the near future, and the corresponding determination of the number of independent polarizations, is a powerful tool to test g…
Can Massive Gravitons be an Alternative to Dark Energy?
Marcio E. S. Alves, Oswaldo D. Miranda, Jose C. N. de Araujo
In this work, we explore some cosmological implications of the model proposed by M. Visser in 1998. In his approach, Visser intends to take in account mass for the graviton by mean…
