VIMOS (VIsible Multi-Object Spectrograph) is a multi-object imaging spectrograph installed at the VLT (Very large Telescope) at the ESO (European Southern Observatory) Paranal Obse…
Mapping the Stellar Dynamics of M31
Helen Merrett, M. Merrifield, K. Kuijken +12
Using the Planetary Nebula Spectrograph, we have observed and measured the velocities for some 2764 PNe in the disk and halo of the Andromeda galaxy. Preliminary analysis using a b…
Planetary Nebulae as Tracers of the Intergalactic Stellar Background: a Population Synthesis Theoretical Approach
Alberto Buzzoni, Magda Arnaboldi
We wish to assess the relationship between the population of planetary nebulae (PNe) and a given parent stellar population from a theoretical point of view. Our results rely on ori…
Galaxy dynamics with the Planetary Nebula Spectrograph
N. R. Napolitano, A. J. Romanowsky, N. G. Douglas +6
The Planetary Nebula Spectrograph is a dedicated instrument for measuring radial velocity of individual Planetary Nebulae (PNe) in galaxies. This new instrument is providing crucia…
