Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Mapping formation pathways of nuclear star clusters across galaxies
Francesca Pinna, Isabel Pérez, Anna Ferré-Mateu +21
Nuclear star clusters (NSCs) are dense, compact stellar systems only a few parsecs across, located at galaxy centers. Their small sizes make them difficult to resolve spatially. NS…

Why the Northern Hemisphere Needs a 30-40m Telescope and the Science at Stake: Shaping Galaxies and Their Stars with Stellar Population Gradients, IMF Variations and Environmental Drivers in Cluster Early-Type Galaxies
A. Vazdekis, P. Sánchez-Blázquez, A. Ferré-Mateu +23
This white paper highlights how stellar population gradients, chemical abundance patterns, stellar initial mass function (IMF) variations, and structural signatures in early-type g…
The Nuclear Star Cluster of M 74: a fossil record of the very early stages of a star-forming galaxy
Francesca Pinna, Nils Hoyer, Jairo Méndez Abreu +13
Nuclear star clusters (NSC) are dense and compact stellar systems, of sizes of few parsecs, located at galactic centers. Their properties and formation mechanisms seem to be tightl…
Azimuthal offsets in spiral arms of nearby galaxies
Miguel Querejeta, Sharon E. Meidt, Yixian Cao +28
Spiral arms play a central role in disc galaxies, but their dynamical nature remains a long-standing open question. Azimuthal offsets between molecular gas and star formation are e…
Do spiral arms enhance star formation efficiency?
Miguel Querejeta, Adam K. Leroy, Sharon E. Meidt +32
Spiral arms are some of the most spectacular features in disc galaxies, and also present in our own Milky Way. It has been argued that star formation should proceed more efficientl…
The effects of environment on galaxies' dynamical structures: From simulations to observations
Yuchen Ding, Ling Zhu, Annalisa Pillepich +4
We studied the effects of cluster environments on galactic structures by using the TNG50 cosmological simulation and observed galaxies in the Fornax cluster. We focused on galaxies…
PHANGS-HST catalogs for 100,000 star clusters and compact associations in 38 galaxies: I. Observed properties
Daniel Maschmann, Janice C. Lee, David A. Thilker +24
We present the largest catalog to-date of star clusters and compact associations in nearby galaxies. We have performed a V-band-selected census of clusters across the 38 spiral gal…

We study young massive clusters (YMCs) in their embedded "infant" phase with ALMA, HST, and JWST observations targeting the central starburst ring in NGC…
Validating full-spectrum fitting with a synthetic integral-field spectroscopic observation of the Milky Way
Zixian Wang, Michael R. Hayden, Sanjib Sharma +5
Ongoing deep IFS observations of disk galaxies provide opportunities for comparison with the Milky Way (MW) to understand galaxy evolution. However, such comparisons are marred by…
Expanding on the Fundamental Metallicity Relation in Dwarf Galaxies with MUSE
Teodora-Elena Bulichi, Katja Fahrion, François Mernier +10
The mass-metallicity relation (MZR) represents one of the most important scaling relations in the context of galaxy evolution, comprising a positive correlation between stellar mas…
The Gas Morphology of Nearby Star-Forming Galaxies
S. K. Stuber, E. Schinnerer, T. G. Williams +22
The morphology of a galaxy stems from secular and environmental processes during its evolutionary history. Thus galaxy morphologies have been a long used tool to gain insights on g…
Fuelling the nuclear ring of NGC 1097
Mattia C. Sormani, Ashley T. Barnes, Jiayi Sun +24
Galactic bars can drive cold gas inflows towards the centres of galaxies. The gas transport happens primarily through the so-called bar ``dust lanes'', which connect the galactic d…
