Dynamical Friction in Nonlocal Gravity

Abstract We study dynamical friction in the Newtonian regime of nonlocal gravity (NLG), which is a classical generalization Einstein’s theory gravitation. The aspect NLG simulates dark matter. attributes resulting effective matter are described and main physical predictions NLG, has characteristic length scale order 1 kpc, for galactic dynamics presented. Within framework we derive analog Chandrasekhar’s formula friction. astrophysical implications results apparent rotation central bar subject to barred spiral galaxy briefly discussed.
