Hector Galaxy Survey: Linking the low- and high-mass ends of the initial mass function in star-forming galaxies
Diego Salvador, Andrew Hopkins, Matt Owers +30
The stellar initial mass function (IMF) is a fundamental ingredient in galaxy evolution, linking observed integrated light to galaxy properties. Constraining the full IMF shape bey…
Hidden mass in early galaxies revealed by bottom-heavy initial mass functions
Chloe M. Cheng, Martje Slob, Mariska Kriek +21
James Webb Space Telescope (JWST) observations have revealed that massive galaxies formed and evolved faster than predicted by galaxy formation models, with many having already ass…
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…
Disc growth and vertical heating of lenticular galaxies in the Fornax cluster
Marie Martig, Francesca Pinna, Jesús Falcón-Barroso +3
We present a detailed analysis of the vertical and radial structure of mono-age stellar populations in three edge-on lenticular galaxies (FCC 153, FCC 170, and FCC 177) in the Forn…
Elemental abundance ratios for the bulge of M31
F. La Barbera, A. Vazdekis, F. Matteucci +3
We present radial trends of metallicity ([Fe/H]) and abundance ratios ([X/Fe]) for several chemical elements -- including C, N, Na, and the so-called alpha-elements (O, Mg, Si, Ca,…
Clues to inside-out quenching in quiescent galaxies at : Age, Fe-, and Mg-abundance gradients from JWST-SUSPENSE
Chloe M. Cheng, Martje Slob, Mariska Kriek +16
[Abridged] Spatially resolved stellar populations of massive quiescent galaxies at cosmic noon provide powerful insights into quenching and assembly mechanisms. Previous photometri…
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…
Counting stars from the integrated spectra of galaxies
I. Martín-Navarro, A. Vazdekis
Over the last decades, evolutionary population synthesis models have powered an unmatched leap forward in our understanding of galaxies. From dating the age of the first galaxies i…
Relatively young thick disks in star-forming late-type galaxies
Natascha Sattler, Francesca Pinna, Sebastien Comerón +4
We trace the evolution of eight edge-on star-forming disk galaxies by analyzing stellar population properties of their thin and thick disks. These galaxies have relatively low stel…
INSPIRE: INvestigating Stellar Population In RElics -- VII. The local environment of ultra-compact massive galaxies
Diana Scognamiglio, Chiara Spiniello, Mario Radovich +15
Relic galaxies, the oldest ultra-compact massive galaxies (UCMGs), contain almost exclusively "pristine" stars formed during an intense star formation (SF) burst at high redshift.…
Deriving the star formation histories of galaxies from spectra with simulation-based inference
Patricia Iglesias-Navarro, Marc Huertas-Company, Ignacio Martín-Navarro +2
High-resolution galaxy spectra encode information about the stellar populations within galaxies. The properties of the stars, such as their ages, masses, and metallicities, provide…
Unveiling the (in)consistencies among the galaxy stellar mass function, star formation histories, satellite abundances and intracluster light from a semi-empirical perspective
Hao Fu, Francesco Shankar, Mohammadreza Ayromlou +16
In a hierarchical, dark matter-dominated Universe, stellar mass functions (SMFs), galaxy merger rates, star formation histories (SFHs), satellite abundances, and intracluster light…
[Mg/Fe] and variable initial mass function: Revision of [/Fe] for massive galaxies
Emilie Pernet, Alina Böcker, Ignacio Martín-Navarro
Observations of nearby massive galaxies have revealed that they are older and richer in metals and magnesium than their low-mass counterparts. In particular, the overabundance of m…
Radial constraints on the Initial Mass Function from TiO features and Wing-Ford band in Early-type Galaxies
F. La Barbera, A. Vazdekis, I. Ferreras +5
At present, the main challenge to the interpretation of variations in gravity-sensitive line strengths as driven by a non-universal initial mass function (IMF), lies in understandi…
