A Duality in the Origin of Bulges and Spheroidal Galaxies
Studying the resolved stellar populations of the different structural components that build massive galaxies directly unveils their assembly history. We aim at...
CEERS Key Paper. IV. A Triality in the Nature of HST-dark Galaxies
The new capabilities that JWST offers in the near- and mid-infrared (IR) are used to investigate in unprecedented detail the nature of optical/near-IR-faint...
From Naked Spheroids to Disky Galaxies: How Do Massive Disk Galaxies Shape Their Morphology?
We investigate the assembly history of massive disk galaxies and describe how they shape their morphology through cosmic time. Using SHARDS and HST data, we...
Recovering Age-Metallicity Distributions from Integrated Spectra: Validation with MUSE Data of a Nearby Nuclear Star Cluster
Current instruments and spectral analysis programs are now able to decompose the integrated spectrum of a stellar system into distributions of ages and...
Timing the r-process Enrichment of the Ultra-faint Dwarf Galaxy Reticulum II
The ultra-faint dwarf galaxy Reticulum II (Ret II) exhibits a unique chemical evolution history, with ${72}_{-12}^{+10}$ % of its stars strongly enhanced in r...
