© ESO, 2014. Context. Stellar population studies of globular clusters have suggested that the brightest clusters in the Galaxy might actually be the remnant nuclei of dwarf spheroidal galaxies. If the present Galactic globular clusters formed within...

Constraining the Galaxy's dark halo with RAVE stars (2014)
Journal Article
Piffl, T., Binney, J., McMillan, P. J., Steinmetz, M., Helmi, A., Wyse, R. F. G., …Zwitter, T. (2014). Constraining the Galaxy's dark halo with RAVE stars. Monthly notices, containing papers, abstracts of papers, and reports of the proceedings of the Society, 445(3), 3133-3151. https://doi.org/10.1093/mnras/stu1948

© 2014 The Authors Published by Oxford University Press on behalf of the Royal Astronomical Society. We use the kinematics of ~200 000 giant stars that lie within ~1.5 kpc of the plane to measure the vertical profile of mass density near the Sun. We...

Kinematic modeling of the milky way using the rave and GCS stellar surveys (2014)
Journal Article
Sharma, S., Bland-Hawthorn, J., Binney, J., Freeman, K. C., Steinmetz, M., Boeche, C., …Zwitter, T. (2014). Kinematic modeling of the milky way using the rave and GCS stellar surveys. The Astrophysical journal, 793(1), 51. doi:10.1088/0004-637x/793/1/51

© 2014. The American Astronomical Society. All rights reserved.. We investigate the kinematic parameters of the Milky Way disk using the Radial Velocity Experiment (RAVE) and Geneva-Copenhagen Survey (GCS) stellar surveys. We do this by fitting a kin...

A RAVE investigation on Galactic open clusters: I. Radial velocities and metallicities (2014)
Journal Article
Conrad, C., Scholz, R., Kharchenko, N. V., Piskunov, A. E., Schilbach, E., Röser, S., …Siviero, A. (2014). A RAVE investigation on Galactic open clusters: I. Radial velocities and metallicities. Astronomy and astrophysics, 562, A54. doi:10.1051/0004-6361/201322070

Context. Galactic open clusters (OCs) mainly belong to the young stellar population in the Milky Way disk, but are there groups and complexes of OCs that possibly define an additional level in hierarchical star formation? Current compilations are too... Read More about A RAVE investigation on Galactic open clusters: I. Radial velocities and metallicities.

The RAVE survey: the Galactic escape speed and the mass of the Milky Way (2014)
Journal Article
Scholz, R., Williams, M. E., Matijevič, G., Bienaymé, O., Wyse, R. F., Piffl, T., …Zwitter, T. (2014). The RAVE survey: the Galactic escape speed and the mass of the Milky Way. Astronomy and Astrophysics, 562, A91. doi:10.1051/0004-6361/201322531

We made new estimates of the Galactic escape speed at various Galactocentric radii using the latest data release of the RAdial Velocity Experiment (RAVE DR4). Compared to previous studies we have a database that is larger by a factor of 10, as well a... Read More about The RAVE survey: the Galactic escape speed and the mass of the Milky Way.

A new stellar chemo-kinematic relation reveals the merger history of the milky way disk (2014)
Journal Article
Minchev, I., Chiappini, C., Martig, M., Steinmetz, M., De Jong, R. S., Boeche, C., …Williams, M. (2014). A new stellar chemo-kinematic relation reveals the merger history of the milky way disk. Astrophysical journal. Letters, 781(1), L20. doi:10.1088/2041-8205/781/1/l20

The velocity dispersions of stars near the Sun are known to increase with stellar age, but age can be difficult to determine, so a proxy like the abundance of α elements (e.g., Mg) with respect to iron, [α/Fe], is used. Here we report an unexpected b... Read More about A new stellar chemo-kinematic relation reveals the merger history of the milky way disk.
