Scalar perturbations in gravity using the covariant approach
Shambel Sahlu, Joseph Ntahompagaze, Amare Abebe +2
The cosmological scalar perturbations of standard matter are investigated in the context of extended teleparallel gravity theories using the covariant formalism. After…

The Chaplygin gas as a model for modified teleparallel gravity?
Shambel Sahlu, Joseph Ntahompagaze, Maye Elmardi +1
This paper explores the possibility of treating the exotic Chaplygin-gas (CG) fluid model as some manifestation of an gravitation. To this end, we use the different cosmolog…
