Description
There is a growing body of work utilising N-body simulations with
alternative gravity theories, but simulations at a galactic scale
remain a relatively unexplored area. In this work, we present the
first simulated galaxy rotation curves under f(R) gravity to our
knowledge. The f(R) gravity solver MG-GADGET (Puchwein et al. 2013)
is employed statically on pre-simulated spiral galaxies, leading to
solutions for the rotation curves and screening radii under HuSawicki
f(R) gravity. It is shown that under certain parameter
regimes, the so-called 'fifth force' yields observable signatures,
which can be exploited to constrain departures from classical
gravity.
