Kinematic properties of early-type galaxy haloes using planetary nebulae
L. Coccato, O. Gerhard, M. Arnaboldi +11
We present new planetary nebulae (PNe) positions, radial velocities, and magnitudes for 6 early-type galaxies obtained with the Planetary Nebulae Spectrograph, their two-dimensiona…
Probing the kinematics of early-type galaxy halos using planetary nebulae
L. Coccato, O. Gerhard, M. Arnaboldi +11
We present first results of a study of the halo kinematics for a sample of early type galaxies using planetary nebulae (PNe) as kinematical tracers. PNe allow to extend up to sever…
Reality of Moving Groups in the Galaxy
G. M. De Silva, K. C. Freeman, J. Bland-Hawthorn +1
The existence of old dispersed stellar groups within the Milky Way disk is still controversial. Are they the debris of ancient star-forming aggregates, or short-lived artifacts of…
The PN.S Elliptical Galaxy Survey: the dark matter in NGC 4494
N. R. Napolitano, A. J. Romanowsky, L. Coccato +12
We present new Planetary Nebula Spectrograph observations of the ordinary elliptical galaxy NGC 4494, resulting in positions and velocities of 255 PNe out to 7 effective radii (25…
Estimation of the Tilt of the Stellar Velocity Ellipsoid from RAVE and Implications for Mass Models
A. Siebert, O. Bienaymé, J. Binney +16
We present a measure of the inclination of the velocity ellipsoid at 1 kpc below the Galactic plane using a sample of red clump giants from the RAVE DR2 release. We find that the v…
Diffuse interstellar bands in RAVE Survey spectra
U. Munari, L. Tomasella, M. Fiorucci +19
We have used spectra of hot stars from the RAVE Survey in order to investigate the visibility and properties of five diffuse interstellar bands previously reported in the literatur…
The Radial Velocity Experiment (RAVE): second data release
T. Zwitter, A. Siebert, U. Munari +51
We present the second data release of the Radial Velocity Experiment (RAVE), an ambitious spectroscopic survey to measure radial velocities (RVs) and stellar atmosphere parameters…
Fashionably Late? Building up the Milky Way's Inner Halo
H. L. Morrison, A. Helmi, J. Sun +9
Using a sample of 248 metal-poor stars (RR Lyraes, red giants and RHB stars) which is remarkable for the accuracy of its 6-D kinematical data, we find a new component for the local…
Galactic kinematics with RAVE data: I. The distribution of stars towards the Galactic poles
L. Veltz, O. Bienaymé, K. C. Freeman +16
We analyze the distribution of G and K type stars towards the Galactic poles using RAVE and ELODIE radial velocities, 2MASS photometric star counts, and UCAC2 proper motions. The c…
Expansion velocities and core masses of bright planetary nebulae in the Virgo cluster
Magda Arnaboldi, Michelle Doherty, Ortwin Gerhard +5
The line-of-sight velocities and [OIII] 5007 AA expansion velocities are measured for 11 planetary nebulae (PNs) in the Virgo cluster core, at 15 Mpc distance, with the FLAMES spec…
