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 $α$ 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 $α$ arm. With the third PN.S arm, the H $α$ arm, we measure…

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…
