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 flattening of dark matter halo of Centaurus A galaxy (NGC 5128) out to 40 kpc
Tadeja Veršič, Marina Rejkuba, Magda Arnaboldi +4
Cosmological simulations predict dark matter shapes that deviate from spherical symmetry. The exact shape depends on the prescription of the simulation and the interplay between da…
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…
INSPIRE: INvestigating Stellar Population In RElics IV. The Initial Mass Function slope in relics
I. Martin-Navarro, C. Spiniello, C. Tortora +10
In the last decade, growing evidence has emerged supporting a non-universal stellar Initial Mass Function (IMF) in massive galaxies, with a larger number of dwarf stars with respec…
INSPIRE: INvestigating Stellar Population In RElics III. Second data release (DR2): testing the systematics on the stellar velocity dispersion
G. D'Ago, C. Spiniello, L. Coccato +15
This is the second data release (DR2) of the INvestigating Stellar Population In RElics (INSPIRE) project, comprising 21 new systems with observations completed before March 2022.…
The survey of Planetary Nebulae in Andromeda (M31): I. Imaging the disk and halo with MegaCam@CFHT
Souradeep Bhattacharya, Magda Arnaboldi, Johanna Hartke +4
The Andromeda (M31) galaxy subtends nearly 100 sq. deg. on the sky, with severe contamination from the Milky Way halo stars whose surface density displays a steep gradient across t…
