Abstract: We formulate a model for noncompact spherical charged objects in the framework of noncommutative field theory. The Einstein—Maxwell field equations are solved with charged anisotropic fluid. We choose matter and charge densities as functions of the two parameters, instead of defining these quantities in terms of the Gaussian distribution function. It is found that the corresponding densities and the Ricci scalar are singular in origin, whereas the metric is nonsingular, indicating a spacelike singularity. The numerical solution of the horizon equation implies that there are two or one or no horizon(s), depending on the mass. We also evaluate the Hawking temperature and find that a black hole with two horizons is evaporated to an extremal black hole with one horizon.
