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…

Why the Northern Hemisphere Needs a 30-40m Telescope and the Science at Stake: Ultra-Low-Mass Dwarf Galaxies Across the Boreal Cosmic Web

J. Alfonso L. Aguerri, Jesús Falcón-Barroso, María Argudo-Fernández +22

Dwarf galaxies dominate the galaxy population in the nearby Universe and occupy the regime where feedback, reionization, and environment exert their strongest influence on galaxy f…

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…

Cosmic Threads: Interlinking the Stellar Initial Mass Function from Star-Birth to Galaxies

Tereza Jerabkova, Donatella Romano, Pavel Kroupa +19

The stellar initial mass function (sIMF) describes the distribution of stellar masses formed in a single star formation event in a molecular cloud clump. It is fundamental to astro…

TP-AGB stars and stellar population properties of a post-starburst galaxy at through optical and NIR spectroscopy with JWST

Davide Bevacqua, Paolo Saracco, Francesco La Barbera +11

We present a detailed optical and NIR spectral analysis of J-138717, a post-starburst galaxy at observed with JWST/NIRSpec, for which we derive a stellar mass of $3.5…

ZF-UDS-7329: A relic galaxy in the early Universe

Eduardo A. Hartmann, Ignacio Martín-Navarro, Marc Huertas-Company +4

The formation time scales of quiescent galaxies can be estimated in two different ways: by their star formation history and by their chemistry. Previously, the methods yielded conf…
