DOI: 10.1093/mnras/stz2889
Abstract: We examine the accretion of matter on to a black hole in scalar–tensor–vector gravity (STVG) also known as modified gravity (MOG). The gravitational constant is G = GN(1 + α) where α is a parameter taken… read more here.

DOI: 10.3390/universe7100358
Abstract: The recent data release by the Planck satellite collaboration presents a renewed challenge for modified theories of gravitation. Such theories must be capable of reproducing the observed angular power spectrum of the cosmic microwave background… read more here.
