Abstract: In the Eddington-inspired-Born-Infeld theory, we consider a metric tensor g, an auxiliary tensor q, a scalar field and an electromagnetic field in Bondi coordinates. Using ‘the null tetrad’ associated with each metric, we derive a… read more here.

DOI: 10.1103/physrevd.98.024033
Abstract: We study here the gravitational collapse of dust in $(2+1)$-dimensional spacetimes for the formation of black holes (BH) and naked singularities (NS) as final states in a modified theory of gravity, with vanishing cosmological constant.… read more here.

DOI: 10.1142/s0218271819501670
Abstract: In this paper, we study the cosmological evolution of the universe filled with a perfect fluid in the Eddington-inspired-Born–Infeld gravity. Applying an alternative method in which the evolution of the scale factor for this theory… read more here.
