A Test of MONDian Gravity in sim300 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.
