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…
Exploring Disk Galaxy Dynamics Using IFU Data
E. Noordermeer, M. R. Merrifield, A. Aragon-Salamanca
In order to test the basic equations believed to dictate the dynamics of disk galaxies, we present and analyze deep two-dimensional spectral data obtained using the PPAK integral f…
Dearth of dark matter or massive dark halo? Mass-shape-anisotropy degeneracies revealed by NMAGIC dynamical models of the elliptical galaxy NGC 3379
F. De Lorenzi, O. Gerhard, L. Coccato +10
Recent results from the Planetary Nebula Spectrograph (PN.S) survey have revealed a rapidly falling velocity dispersion profile in the nearby elliptical galaxy NGC 3379, casting do…
