Abstract: In this paper we will consider the most general quadratic curvature action of massless gravity in 3 space time dimensions which is parity invariant and torsion free and contains the same off-shell degrees of freedom… read more here.

Abstract: Recent study has shown that a nonsingular oscillating potential—a feature of infinite derivative gravity theories—matches current experimental data better than the standard General Relativity potential. In this work, we show that this nonsingular oscillating potential… read more here.

Abstract: General Relativity is known to produce singularities in the potential generated by a point source. Our universe can be modelled as a de Sitter (dS) metric and we show that ghost-free Infinite Derivative Gravity (IDG)… read more here.

DOI: 10.1103/physrevd.98.044049
Abstract: The Hulse-Taylor binary provides possibly the best test of GR to date. We find the modified quadrupole formula for infinite derivative gravity (IDG). We investigate the backreaction formula for propagation of gravitational waves, found previously… read more here.
