Cosmological test on viscous bulk models using Hubble parameter measurements and type Ia supernovae data
Abstract From a phenomenological point of view, we analyze the dynamics of the Universe at late times by introducing a polynomial and hyperbolic bulk viscosity into the Einstein field equations respectively. We constrain their free parameters using the observational Hubble parameter data and the Typ...
