Constraining gravity with bulk viscosity
Y. Myrzakulov, O. Donmez, M. Koussour +3
We investigate the influence of bulk viscosity on late-time cosmic acceleration within an extended gravity framework, where the non-metricity is non-minimally coupl…

Bulk viscous matter in gravity: A path to cosmic acceleration
Kairat Myrzakulov, O. Donmez, M. Koussour +3
In this paper, we investigate the effects of varying bulk viscosity coefficients on cosmic evolution within the framework of teleparallel gravity. We…
