Predicted Trends in Milky Way Bulge Proper Motion Rotation Curves: future Prospects for HST and LSST
Steven Gough-Kelly, Victor P. Debattista, William I. Clarkson +5
We use an -body+smoothed particle hydrodynamics simulation of an isolated barred galaxy to study the age dependence of bulge longitudinal proper motion () rotation curves.…
Identification of an X-ray Pulsar in the BeXRB system IGR J182191347
B. O'Connor, E. Gogus, D. Huppenkothen +25
We report on observations of the candidate Be/X-ray binary IGR J182191347 with \textit{Swift}/XRT, \textit{NuSTAR}, and \textit{NICER} during Type-I outbursts in March and June…
A stellar census in globular clusters with MUSE. A new perspective on the multiple main sequences of Centauri
M. Latour, A. Calamida, T. -O. Husser +3
Cen is a rare example of a globular cluster where the iron abundance of the stars spans more than one order of magnitude. Many spectroscopic investigations of its red-giant- an…
Variable stars in Local Group Galaxies -- V. The fast and early evolution of the low-mass Eridanus II dSph galaxy
C. E. Martínez-Vázquez, M. Monelli, S. Cassisi +18
We present a detailed study of the variable star population of Eridanus II (Eri II), an ultra-faint dwarf galaxy that lies close to the Milky Way virial radius. We analyze multi-ep…
The star formation history of Eridanus II: on the role of SNe feedback in the quenching of ultra-faint dwarf galaxies
C. Gallart, M. Monelli, T. Ruiz-Lara +17
Eridanus II (EriII) is an ultra-faint dwarf (UFD) galaxy (M_V=-7.1) located at a distance close to the Milky Way virial radius. Early shallow color-magnitude diagrams (CMD) indicat…
