Astrophysical implications of Mashhoon-Hehl nonlocal gravity theory 

Abstract: In this talk I review our recent investigations on the astrophysical implications of Mashhoon-Hehl nonlocal gravity (NLG) theory. I discuss the physical characteristics of the effective dark matter in NLG specifically within the dwarf galaxies like the ultra-diffuse galaxies AGC 114905, 242019, and 219533. Furthermore, I present the results of some high-resolution galactic simulations conducted in NLG, and show that galactic disks appear with different morphological features in NLG compared to the standard cold dark matter picture. Also, I discuss the analytical computation of the dynamical friction force in NLG in the presence and absence of galactic tidal effects. This force plays a significant role in connection with the dynamics of the stellar bars.
