The Initial Mass Function of the Inner Galaxy Measured From OGLE-III Microlensing Timescales
Christopher Wegg, Ortwin Gerhard, Matthieu Portail
We use the timescale distribution of ~3000 microlensing events measured by the OGLE-III survey, together with accurate new made-to-measure dynamical models of the Galactic bulge/ba…
Chemodynamical Modelling of the Galactic Bulge and Bar
Matthieu Portail, Christopher Wegg, Ortwin Gerhard +1
We present the first self-consistent chemodynamical model fitted to reproduce data for the galactic bulge, bar and inner disk. We extend the Made-to-Measure method to an augmented…
Revisiting the Tale of Hercules: how stars orbiting the Lagrange points visit the Sun
Angeles Pérez-Villegas, Matthieu Portail, Christopher Wegg +1
We propose a novel explanation for the Hercules stream consistent with recent measurements of the extent and pattern speed of the Galactic bar. We have adapted a made-to-measure dy…
