The Chaplygin gas as a model for modified teleparallel gravity?

European Physical Journal C: Particles and Fields, 2019
This paper explores the possibility of treating the exotic Chaplygin-gas (CG) fluid model as some manifestation of an f(T) gravitation. To this end, we use the different cosmological CG equations of state, compare them with the equation of state for the ...

Probing a regular non-minimal Einstein-Yang-Mills black hole with gravitational lensings

Physics Letters B, 2019
We investigate weak and strong deflection gravitational lensings of the regular black hole predicted by a non-minimal Einstein–Yang–Mills theory. We find that its weak deflection lensing is the same as a Reissner–Nordström black hole's.
