Modified Gravitation Theory (MOG) and the aLIGO GW190521 Gravitational Wave Event

Abstract

A consequence of adopting a modified gravitational theory (MOG) for the aLIGO GW190521 gravitational wave detection involving binary black hole sources is to fit the aLIGO strain and chirp data with lower mass, compact coalescing binary systems such as neutron star-neutron star (NS-NS), black hole - neutron star (BH-NS), and black hole-black hole (BH-BH) systems. In MOG BH - BH component masses can be smaller than the component masses $m_1=85M_{\odot }$ and $m_2=66M_{\odot }$ inferred from the aLIGO GW190521 gravitational wave event. This reduces the mass of the final remnant mass $M_f=150M_{\odot }$ and allows the primary, secondary and final remnant masses of the black holes to be formed by conventional stellar collapse models.
