From relics to stripped systems: the environmental origin of compact galaxies
Guangwen Chen, J. Alfonso L. Aguerri, Carlos del Burgo +1
Compact galaxies represent a key population for understanding galaxy evolution, but the relative role of internal structure and environment in shaping their origin remains unclear.…
The onset of stellar bars at Cosmic Noon. Bar-driven quenching and AGN co-evolution in a mature disc galaxy
Luca Costantin, Lorenzo Morelli, Cristina Cabello +15
The paper analyzes a barred spiral galaxy at redshift 1.17 using JWST NIRSpec data, showing that the bar formed early (z~5) and contributed to long‑term star‑formation quenching wh…
Hierarchical assembly in action: a galaxy tail from a disrupting group in the Virgo cluster outskirts
J. Alfonso L. Aguerri, Stefano Zarattini, Virginia Cuomo +1
Group environments are thought to play a key role in shaping galaxy evolution prior to cluster accretion. However, direct observational evidence linking group--cluster interactions…
Galaxy transformation across the cosmic web: The influence zone of filaments
J. A. L. Aguerri, S. Zarattini
The matter distribution in the Universe exhibits a rich variety of structures forming the cosmic web. These structures arise from the anisotropic gravitational collapse of primordi…
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, MarÃa 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…
