Impacts of perfect fluid dark matter on spacetime geometry: the exponential metric

Abstract Astrophysical observations provide compelling evidence for the existence of dark matter, a non-luminous component dominating the universe’s mass-energy budget. Its gravitational influence is well-established on galactic scales; however, dark matter’s precise nature and effect on spacetime g...
