Kinematically cold and warm planetary nebulae samples, HII regions and supernovae remnants in the disc of the face-on spiral galaxy NGC 628 (M74) -- The Planetary Nebulae Spectrograph with the H arm
Magda Arnaboldi, Ortwin Gerhard, Surya Aniyan +14
We present the results for the galaxy NGC 628 observed with the Planetary Nebulae Spectrograph (PN.S) equipped with the H arm. With the third PN.S arm, the H arm, we measure…
Planetary Nebula Spectrograph survey of S0 galaxy kinematics. II. Clues to the origins of S0 galaxies
A. Cortesi, M. R. Merrifield, L. Coccato +11
The stellar kinematics of the spheroids and discs of S0 galaxies contain clues to their formation histories. Unfortunately, it is difficult to disentangle the two components and to…
The Planetary Nebula Spectrograph survey of S0 galaxy kinematics. Data and Overview
A. Cortesi, M. Arnaboldi, L. Coccato +11
The origins of S0 galaxies remain obscure, with various mechanisms proposed for their formation, likely depending on environment. These mechanisms would imprint different signature…
Unravelling the origins of S0 galaxies using maximum likelihood analysis of planetary nebulae kinematics
A. Cortesi, M. R. Merrifield, M. Arnaboldi +12
To investigate the origins of S0 galaxies, we present a new method of analyzing their stellar kinematics from discrete tracers such as planetary nebulae. This method involves binni…
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…
