A Test of MONDian Gravity in $\sim$300 pressure supported elliptical
  galaxies from the MaNGA survey
  Pressure supported systems modeled under MONDian extended gravity are
expected to show an outer flattening in their velocity dispersion profiles. A
characteristic scaling between the amplitude of the asymptotic velocity
dispersion and the radius at which the flattening occurs is also expected. By
comprehensively analyzing the dynamical behavior of $\sim$300 extremely low
rotating elliptical galaxies from the MaNGA survey, we show this type of
pressure supported systems to be consistent with MONDian expectations, for a
range of central velocity dispersion values of $60 km/s < \sigma_{central}< 280
km/s $ and asymptotic velocity dispersion values of $28km/s <
\sigma_{\infty}<250 km/s$. We find that a universal velocity dispersion profile
accurately describes the studied systems; the predicted kinematics of extended
gravity are verified for all well observed galaxies.
