    Bar-driven Gas Dynamics of M31
    (2024) Feng, Zi-Xuan; Li, Zhi; Shen, Juntai; Gerhard, Ortwin; Saglia, R. P.; Blana, Matias; Li, Hui; Jing, Yingjie
    The large-scale gaseous shocks in the bulge of M31 can be naturally explained by a rotating stellar bar. We use gas dynamical models to provide an independent measurement of the bar pattern speed in M31. The gravitational potentials of our simulations are from a set of made-to-measure models constrained by stellar photometry and kinematics. If the inclination of the gas disk is fixed at i = 77 degrees, we find that a low pattern speed of 16-20 km s-1 kpc-1 is needed to match the observed position and amplitude of the shock features, as shock positions are too close to the bar major axis in high omega b models. The pattern speed can increase to 20-30 km s-1 kpc-1 if the inner gas disk has a slightly smaller inclination angle compared with the outer one. Including subgrid physics such as star formation and stellar feedback has minor effects on the shock amplitude, and does not change the shock position significantly. If the inner gas disk is allowed to follow a varying inclination similar to the H i and ionized gas observations, the gas models with a pattern speed of 38 km s-1 kpc-1, which is consistent with stellar-dynamical models, can match both the shock features and the central gas features.

    In statistics, samples are drawn from a population in a data-generating process (DGP). Standard errors measure the uncertainty in estimates of population parameters. In science, evidence is generated to test hypotheses in an evidence-generating process (EGP). We claim that EGP variation across researchers adds uncertainty-nonstandard errors (NSEs). We study NSEs by letting 164 teams test the same hypotheses on the same data. NSEs turn out to be sizable, but smaller for more reproducible or higher rated research. Adding peer-review stages reduces NSEs. We further find that this type of uncertainty is underestimated by participants.
