The chemistry of stars in the bar of the Milky Way
C. Wegg, A. Rojas-Arriagada, M. Schultheis +1
We use a sample of 938 red clump giant stars located in the direction of the galactic long bar to study the chemistry of Milky Way bar stars. Kinematically separating stars on bar…
Tracing Hercules in Galactic azimuth with Gaia DR2
G. Monari, B. Famaey, A. Siebert +4
The second data release of the Gaia mission has revealed, in stellar velocity and action space, multiple ridges, the exact origin of which is still debated. Recently, we demonstrat…
7.1 keV sterile neutrino dark matter constraints from a deep Chandra X-ray observation of the Galactic bulge Limiting Window
F. Hofmann, C. Wegg
Recently an unidentified emission line at 3.55 keV has been detected in X-ray spectra of clusters of galaxies. The line has been discussed as a possible decay signature of 7.1 keV…
The Milky Way bar/bulge in proper motions: a 3D view from VIRAC & Gaia
Jonathan P. Clarke, Christopher Wegg, Ortwin Gerhard +3
We have derived absolute proper motions of the entire Galactic bulge region from VIRAC and Gaia. We present these as both integrated on-sky maps and, after isolating standard candl…
