Query: The Effects of Inertial Forces on the Dynamics of Disk Galaxies   When dealing with galactic dynamics, or more specifically, with galactic
rotation curves, one basic assumption is always taken: the frame of reference
relative to which the rotational velocities are given is assumed to be
inertial. In other words, fictitious forces are assumed to vanish relative to
the observational frame of a given galaxy. It might be interesting, however, to
explore the outcomes of dropping that assumption; that is, to search for
signatures of non-inertial behavior in the observed data. In this work, we show
that the very discrepancy in galaxy rotation curves could be attributed to
non-inertial effects. We derive a model for spiral galaxies that takes into
account the possible influence of fictitious forces and find that the
additional terms in the new model, due to fictitious forces, closely resemble
dark halo profiles. Following this result, we apply the new model to a wide
sample of galaxies, spanning a large range of luminosities and radii. It turns
out that the new model accurately reproduces the structures of the rotation
curves and provides very good fittings to the data.
