The Rich Are Different: Evidence from the RAVE Survey for Stellar Radial Migration
G. Kordopatis, J. Binney, G. Gilmore +21
Using the RAdial Velocity Experiment fourth data release (RAVE DR4), and a new metallicity calibration that will be also taken into account in the future RAVE DR5, we investigate t…
Characterizing the High-Velocity Stars of RAVE: The Discovery of a Metal-Rich Halo Star Born in the Galactic Disk
K. Hawkins, G. Kordopatis, G. Gilmore +21
We aim to characterize high-velocity (HiVel) stars in the solar vicinity both chemically and kinematically using the fourth data release of the RAdial Velocity Experiment (RAVE). W…
Dust and Gas in the Magellanic Clouds from the HERITAGE Herschel Key Project. II. Gas-to-Dust Ratio Variations across ISM Phases
Julia Roman-Duval, Karl Gordon, Margaret Meixner +32
The spatial variations of the gas-to-dust ratio (GDR) provide constraints on the chemical evolution and lifecycle of dust in galaxies. We examine the relation between dust and gas…
Eppur si muove: Positional and kinematic correlations of satellite pairs in the low Z universe
Rodrigo A. Ibata, Benoit Famaey, Geraint F. Lewis +2
We have recently shown (Ibata et al. 2014) that pairs of satellite galaxies located diametrically opposite each other around their host possess predominantly anti-correlated veloci…
Exposing Sgr tidal debris behind the Galactic disk with M giants selected in WISE2MASS
S. E. Koposov, V. Belokurov, D. B. Zucker +5
We show that a combination of infrared photometry from WISE and 2MASS surveys can yield highly pure samples of M giant stars. We take advantage of the new WISE2MASS M giant s…
The almost ubiquitous association of 6.7 GHz methanol masers with dust
J. S. Urquhart, T. J. T. Moore, K. M. Menten +6
We report the results of 870-m continuum observations, using the Large APEX Bolometer Camera (LABOCA), towards 77 class-II, 6.7-GHz methanol masers identified by the Methanol Mu…
The Next Generation Virgo Cluster Survey. XV. The photometric redshift estimation for background sources
A. Raichoor, S. Mei, T. Erben +28
The Next Generation Virgo Cluster Survey is an optical imaging survey covering 104 deg^2 centered on the Virgo cluster. Currently, the complete survey area has been observed in the…
Modeling and predicting the shape of the far-infrared to submillimeter emission in ultra-compact HII regions and cold clumps
D. Paradis, C. Mény, A. Noriega-Crespo +8
Dust properties are very likely affected by the environment in which dust grains evolve. For instance, some analyses of cold clumps (7 K- 17 K) indicate that the aggregation proces…
Monitoring the Dusty S-Cluster Object (DSO/G2) on its Orbit towards the Galactic Center Black Hole
M. Valencia-S., A. Eckart, M. Zajacek +23
We analyse and report in detail new near-infrared (1.45 - 2.45 microns) observations of the Dusty S-cluster Object (DSO/G2) during its approach to the black hole at the center of t…
The influence of supernova remnants on the interstellar medium in the Large Magellanic Cloud seen at 20--600 m wavelengths
Maša Lakićević, Jacco Th. van Loon, Margaret Meixner +20
We present the analysis of supernova remnants (SNRs) in the Large Magellanic Cloud (LMC) and their influence on the environment at far-infrared (FIR) and submillimeter wavelengths.…
The reionization of galactic satellite populations
P. Ocvirk, N. Gillet, D. Aubert +6
We use high resolution simulations of the formation of the local group post-processed by a radiative transfer code for UV photons, to investigate the reionization of the satellite…
A PAndAS view of M31 dwarf elliptical satellites: NGC147 and NGC185
D. Crnojević, A. M. N. Ferguson, M. J. Irwin +9
We exploit data from the Pan-Andromeda Archaeological Survey (PAndAS) to study the extended structures of M31's dwarf elliptical companions, NGC147 and NGC185. Our wide-field, homo…
The Next Generation Virgo Cluster Survey. VIII. The Spatial Distribution of Globular Clusters in the Virgo Cluster
Patrick R. Durrell, Patrick Côté, Eric W. Peng +19
We report on a large-scale study of the distribution of globular clusters (GCs) throughout the Virgo cluster, based on photometry from the Next Generation Virgo Cluster Survey, a l…
Accretion in action: phase space coherence of stellar debris and globular clusters in Andromeda's South-West Cloud
Dougal Mackey, Geraint Lewis, Michelle Collins +13
A central tenet of the current cosmological paradigm is that galaxies grow over time through the accretion of smaller systems. Here, we present new kinematic measurements near the…
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…
Pseudo Three-dimensional Maps of the Diffuse Interstellar Band at 862 nm
Janez Kos, Tomaž Zwitter, Rosemary Wyse +20
The diffuse interstellar bands (DIBs) are absorption lines observed in visual and near infrared spectra of stars. Understanding their origin in the interstellar medium (ISM) is one…
