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…
Testing the nature of S0 galaxies using planetary nebula kinematics in NGC 1023
E. Noordermeer, M. R. Merrifield, L. Coccato +9
We investigate the manner in which lenticular galaxies are formed by studying their stellar kinematics: an S0 formed from a fading spiral galaxy should display similar cold outer d…
A deep kinematic survey of planetary nebulae in the Andromeda Galaxy using the Planetary Nebula Spectrograph
H. R. Merrett, M. R. Merrifield, N. G. Douglas +13
We present a catalogue of positions, magnitudes and velocities for 3300 emission-line objects found by the Planetary Nebula Spectrograph in a survey of the Andromeda Galaxy, M31. O…
Photometric structure of the peculiar galaxy ESO 235-G58
E. Iodice, M. Arnaboldi, L. S. Sparke +3
We present the near-infrared and optical properties of the peculiar galaxy ESO 235-G58, which resembles a late-type ringed barred spiral seen close to face-on. However, the apparen…
Intracluster stellar population properties from N-body cosmological simulations -- I. Constraints at
N. R. Napolitano, M. Pannella, M. Arnaboldi +8
We use a high resolution collisionless simulation of a Virgo--like cluster in a CDM cosmology to determine the velocity and clustering properties of the diffuse stellar componen…
