An automated method for planetary nebula detection with SIGNALS: first applications to NGC 4214 and NGC 4449
Nancy Yang, Johanna Hartke, Martin Bureau +11
Utilising the optical imaging Fourier transform spectrograph SITELLE, the Star-formation, Ionized Gas and Nebular Abundances Legacy Survey (SIGNALS) is designed to study the connec…
Planetary nebulae as tracers of stellar population properties: a pilot study with MUSE
Ana Inés Ennis, Johanna Hartke, Fuyan Bian +4
Planetary nebulae (PNe) are the only single stars in galaxies outside the Local Group that can be used as kinematic tracers of the diffuse light in the extended halo. Analysing the…
Planetary nebulae populations in the haloes of nearby massive early-type galaxies
J. Hartke, M. Arnaboldi, O. Gerhard +8
Planetary nebulae (PNe) are excellent tracers of the metal-poor haloes of nearby early-type galaxies. They are commonly used to trace spatial distribution and kinematics of the hal…
Planetary nebulae as tracers of stellar population properties: unlocking their potential with integral-field spectroscopy
Ana Ennis, Johanna Hartke, Magda Arnaboldi +3
Planetary nebulae (PNe) are essential tracers of the kinematics of the diffuse halo and intracluster light where stellar spectroscopy is unfeasible, due to their strong emission li…
The extended Planetary Nebula Spectrograph (ePN.S) early-type galaxy survey: The specific angular momentum of ETGs
C. Pulsoni, O. Gerhard, S. M. Fall +5
Mass and angular momentum are key parameters of galaxies. Their co-evolution establishes an empirical relation between the specific stellar angular momentum j* and the stellar mass…
