On the HI-Hole and AGB Stellar Population of the Sagittarius Dwarf Irregular Galaxy
Y. Momany, M. Clemens, L. R. Bedin +8
Using two HST/ACS data-sets that are separated by ~2 years has allowed us to derive the relative proper-motion for the Sagittarius dwarf irregular (SagDIG) and reduce the heavy for…
Spectroscopy of the three distant Andromedan satellites Cassiopeia III, Lacerta I, and Perseus I
Nicolas F. Martin, Kenneth C. Chambers, Michelle L. M. Collins +10
We present Keck II/DEIMOS spectroscopy of the three distant dwarf galaxies of M31 Lacerta I, Cassiopeia III, and Perseus I, recently discovered within the Pan-STARRS1 3πimaging sur…
A chemical confirmation of the faint Bootes II dwarf Spheroidal Galaxy
Andreas Koch, R. Michael Rich
We present a chemical abundance study of the brightest confirmed member star of the ultrafaint dwarf galaxy Bootes II from Keck/HIRES high-resolution spectroscopy at moderate signa…
Massive stars in the giant molecular cloud G23.3-0.3 and W41
Maria Messineo, Karl M. Menten, Donald F. Figer +7
Young massive stars and stellar clusters continuously form in the Galactic disk, generating new HII regions within their natal giant molecular clouds and subsequently enriching the…
Chemical and kinematical properties of Galactic bulge stars surrounding the stellar system Terzan 5
Davide Massari, A. Mucciarelli, F. R. Ferraro +8
As part of a study aimed at determining the kinematical and chemical properties of Terzan 5, we present the first characterization of the bulge stars surrounding this puzzling stel…
Young Massive Clusters/Associations in the GMC G23.3-0.3
M. Messineo, K. M. Menten, D. Figer +7
An overview of a spectroscopic survey for massive stars in the direction of the Galactic giant molecular complex G23.3-0.3 is presented (Messineo et al. 2010, and 2014 A&A submitte…
The zCOSMOS Redshift Survey: evolution of the light in bulges and discs since z~0.8
L. A. M. Tasca, L. Tresse, O. Le Fevre +52
We studied the chronology of galactic bulge and disc formation by analysing the relative contributions of these components to the B-band rest-frame luminosity density at different…
The PAndAS Field of Streams: stellar structures in the Milky Way halo toward Andromeda and Triangulum
Nicolas F. Martin, Rodrigo A. Ibata, R. Michael Rich +16
We reveal the highly structured nature of the Milky Way stellar halo within the footprint of the PAndAS photometric survey from blue main sequence and main sequence turn-off stars.…
An empirical mass-loss law for Population II giants from the Spitzer-IRAC survey of Galactic globular clusters
L. Origlia, F. R. Ferraro, S. Fabbri +4
The main aim of the present work is to derive an empirical mass-loss (ML) law for Population II stars in first and second ascent red giant branches. We used the Spitzer InfraRed Ar…
Proper motions for HST observations in three off-axis bulge fields
Mario Soto, Hugo Zeballos, Konrad Kuijken +3
Aims. This is the second in a series of papers that attempt to unveil the kinematic structure of the Galactic bulge through studying radial velocities and proper motions. We report…
Are high velocity peaks in the Milky Way bulge due to the bar?
Zhao-Yu Li, Juntai Shen, R. Michael Rich +2
Recently the commissioning APOGEE observations of the Galactic bulge reported that a significant fraction of stars () are in a cold ( km/s) high velo…
