Accelerated Universe from Modified Chaplygin Gas and Tachyonic Fluid
A cosmological model with an exotic fluid is investigated. We show that the equation of state of this “modified Chaplygin” gas can describe the current accelerated expansion of the universe. We then reexpress it as FRW cosmological model containing a scalar field <inline-formula><math xmlns...
