Isotropic Equivalence of STVG--MOG and CDM and Its Breakdown in Large--Scale Anisotropic Cosmological Observables
John W. Moffat
We show that Scalar-Tensor-Vector Gravity (STVG-MOG) is observationally equivalent to the standard model CDM cosmological model for all probes that depend on isotropic and linea…

Modified Gravity and the Origin of the Excess Radio Galaxy Number-Count Dipole
John. W. Moffat
Recent analyses of wide-area radio-galaxy surveys have reported a statistically significant excess in the cosmic number-count dipole, with an amplitude exceeding the purely kinemat…

Regular Rotating Black Hole: Probing the boundaries of the Radiative Signatures and Jet Power
Subhadip Sau, John W. Moffat
We perform a detailed observational analysis of several galactic X-ray binaries, focusing on the interplay between black hole spin, jet power, and radiative efficiency within the c…
