Rotation curves and dynamical masses of MaNGA barred galaxies

ABSTRACT In this paper we analyse a sample of 46 barred galaxies MaNGA. Our goal is to investigate the stellar kinematics these and obtain their rotation curves. Additionally, aim derive total dynamical masses, as well maximum velocity, in order examine distributions scaling relations. Using Pipe3D dataproducts publicly available obtained curves, which were fitted considering two components an axisymmetric Miyamoto–Nagai gravitational potential. We found wide range velocities (117–340 ${\rm km\, s^{-1}}$), with mean value 200 s^{-1}}$. addition that masses are log(Mstar/M⊙) = 10.1−11.5, 10.8, log(Mdyn/M⊙) 10.4−12.0, 11.1, respectively. strong correlation between mass velocity magnitude, velocity. According results, exhibit similar behaviour normal spiral respect relations, terms distribution However, statistically different from other samples including non-barred galaxies. Finally, analysing show nuclear activity, find no difference curves
