Low-rotating elliptical galaxies in MaNGA
Listed in IVOA Registry (Virtual Observatory)
Pressure-supported systems modeled under Modified Newtonian dynamics (MOND)ian extended gravity are expected to show an outer flattening in their velocity dispersion profiles.
Description
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 ~300 extremely low-rotating elliptical galaxies from the Mapping Nearby Galaxies at APO (MaNGA) survey, we show this type of pressure-supported system to be consistent with MONDian expectations, for a range of central velocity dispersion values of 60 km s^-1^<{sigma}_central_<280km/s and asymptotic velocity dispersion values of 28km/s<{sigma}_\infty_<250km/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.
