Large Magellanic Cloud Globular Clusters in the Near-infrared. I. RR Lyrae in Reticulum

Anupam Bhardwaj, Susmita Das, Prashant Nishad +10

Reticulum is an old, metal-poor, and sparsely populated globular cluster in the outer regions of the Large Magellanic Cloud (LMC) and hosts a rich population of RR Lyrae stars. Bei…

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…

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…

Distance measurements from the internal dynamics of globular clusters: Application to the Sombrero galaxy (M104)

Katja Fahrion, Michael A. Beasley, Anastasia Gvozdenko +7

Globular clusters (GCs) are dense star clusters found in all massive galaxies. Recent work has established that they follow a tight relation between their internal stellar velocity…

Unlocking the physics of dwarf galaxies in the 2040s: The case for a next-generation wide-field spectroscopic facility with fibres and IFUs

Crescenzo Tortora, Daniela Carollo, Leslie Hunt +25

Dwarf galaxies () are the most numerous galaxies in the Universe and critical probes of dark matter, baryonic feedback, and galaxy formation. D…

Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Resolved Stellar Populations Studies in M31 and its Satellites

C. Gallart, E. Fernández-Alvar, A. B. A. Queiroz +48

A 30 m class optical/near-IR telescope in the Northern Hemisphere, equipped for diffraction-limited imaging and high-resolution, multi-object spectroscopy of faint stars, would ena…
