Contribution
It introduces a comparative analysis of two dynamical modeling techniques applied to integral-field data for 25 galaxies, highlighting their agreement and discrepancies.
Findings
Good agreement between the two modeling methods.
Identified systematic differences with published values.
Demonstrated the effectiveness of integral-field kinematics for mass measurements.
Abstract
We investigate the accuracy of mass determinations M_BH of supermassive black holes in galaxies using dynamical models of the stellar kinematics. We compare 10 of our M_BH measurements, using integral-field OASIS kinematics, to published values. For a sample of 25 galaxies we confront our new M_BH derived using two modeling methods on the same OASIS data.
