Chemical abundance patterns at z=1-7: Carbon, Nitrogen, Neon, Sulphur, and Argon abundances from JWST spectroscopy

E. Cataldi, F. Belfiore, M. Curti +22

The relative abundances of chemical elements in the interstellar medium (ISM) trace the history of star formation and chemical enrichment in galaxies. We investigate the abundance…

A model for the ongoing subcluster interaction in Centaurus

Felipe S. Lohmann, Magda Arnaboldi, Michael Hilker +10

Intracluster globular clusters (GCs) preserve the hierarchical and chemical history of galaxy cluster assembly. The nearby Centaurus cluster is believed to be undergoing an interac…

The Merger-Driven Origin of the Vast Extended Stellar Disc Around the Andromeda Galaxy

C. Tsakonas, M. Arnaboldi, F. Hammer +4

The closest giant spiral, the Andromeda galaxy (M31), shows compelling evidence for a recent, gas-rich major merger event. Pronounced substructures in its inner halo and a kinemati…

Looking into the faintEst WIth MUSE (LEWIS): Exploring the nature of ultra-diffuse galaxies in the Hydra-I cluster. VI. A star-forming UDG in Hydra I: a rare UDG or a transition phase?

Luca Rossi, Chiara Buttitta, Goran Doll +21

This paper presents a detailed analysis of a gas-rich star-forming ultra-diffuse galaxy (UDG) as part of the ESO Large Programme 'Looking into the faintEst WIth MUSE (LEWIS)'. Amon…

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…

Galactic Archaeology with the Subaru `Ōnohi`ula Prime Focus Spectrograph Strategic Program

Masashi Chiba, Rosemary F. G. Wyse, Evan N. Kirby +48

The recently commissioned Subaru `Ōnohi`ula Prime Focus Spectrograph (PFS) will obtain spectra from nearly 2,400 fibers that cover 1.24 square degrees. The 360 night Subaru Strateg…

Intracluster globular clusters as tracers of the mass assembly of the Hydra I galaxy cluster

Felipe S. Lohmann, Magda Arnaboldi, Michael Hilker +7

In galaxy clusters, hierarchical assembly predicts the formation of stellar substructures and intracluster light (ICL), a diffuse stellar component tracing the global cluster poten…

Extragalactic Planetary Nebulae (xPNe). Chemical evolution and assembly histories of nearby galaxies using Oxygen and Argon abundances. From the local universe to cosmic dawn

Magda Arnaboldi, Ortwin Gerhard, Martin Roth +6

How galaxies formed and evolved in the expanding Universe is the main science goal of Near-Field Cosmology research. Studies of the properties of galaxies' resolved stars open a wi…

Extragalactic Planetary Nebulae (xPNe). Determining Distances out to 100 Mpc and the Renaissance of the PN Luminosity Function Method

Magda Arnaboldi, Ortwin Gerhard, Martin Roth +9

The discrepancy of the Hubble parameter H0 as measured from the cosmic microwave background versus that found from traditional distance ladder measurements has produced considerabl…

Extragalactic planetary nebulae -- tracers of kinematics and stellar populations out to 100 Mpc

Johanna Hartke, Magda Arnaboldi, Claudia Pulsoni +11

Extragalactic planetary nebulae (xPNe) in galaxies beyond the Local Universe serve as discrete tracers for studying the element abundances and kinematics of galaxies covering a wid…
