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…
INSPIRE: INvestigating Stellar Population In RElics V. A catalogue of ultra-compact massive galaxies outside the local Universe and their degree of relicness
C. Spiniello, G. D'Ago, L. Coccato +18
This paper presents the third data release of the INvestigating Stellar Population In RElics (INSPIRE) project, comprising 52 ultra-compact massive galaxies (UCMGs) observed with t…
Ultra diffuse galaxies in the Hydra I cluster from the LEWIS Project: Phase-Space distribution and globular cluster richness
Duncan Forbes, Jonah Gannon, Enrichetta Iodice +18
Although ultra diffuse galaxies (UDGs) are found in large numbers in clusters of galaxies, the role of the cluster environment in shaping their low surface brightness and large siz…
Looking into the faintEst WIth MUSE (LEWIS): on the nature of ultra-diffuse galaxies in the Hydra-I cluster.I. Project description and preliminary results
Enrichetta Iodice, Michael Hilker, Goran Doll +23
Looking into the faintEst WIth MUSE (LEWIS) is an ESO large observing programme aimed at obtaining the first homogeneous integral-field spectroscopic survey of 30 extremely low-sur…
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 Andromeda Galaxy's Last Major Merger: Constraints from the survey of Planetary Nebulae
Souradeep Bhattacharya, Magda Arnaboldi, Ortwin Gerhard +7
The Andromeda galaxy (M 31) has experienced a tumultuous merger history as evidenced by the many substructures present in its inner halo. We use planetary nebulae (PNe) as chemodyn…
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…
Supermassive black hole mass in the massive elliptical galaxy M87 from integral-field stellar dynamics using OASIS and MUSE with adaptive optics: assessing systematic uncertainties
David A. Simon, Michele Cappellari, Johanna Hartke
The massive elliptical galaxy M87 has been the subject of several supermassive black hole mass measurements from stellar dynamics, gas dynamics, and recently the black hole shadow…
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.…
