GLACE survey: OSIRIS/GTC multi-object spectroscopy of the rich galaxy cluster ZwCl 0024.0+1652 at z~0.4. III. The mass-SFR relation and the quenching of cluster galaxies

Simon B. De Daniloff, Ángel Bongiovanni, Miguel Sánchez-Portal +21

Galaxy clusters are among the largest and densest structures in the Universe. Their high density generally increases the suppression of star formation, known as quenching, altering…

The role of young and evolved stars in the heating of dust in local galaxies

Vidhi Tailor, Viviana Casasola, Francesca Pozzi +9

Context. Dust is a fundamental component of the interstellar medium (ISM) and plays a critical role in galaxy evolution. Dust grains influence the ISM by cooling the gas, altering…

New clues on the extended HeII ionization in IZw18 from GTC/MEGARA and JWST/MIRI

A. Arroyo-Polonio, C. Kehrig, J. M. Vílchez +5

IZw18 is one of the lowest-metallicity star-forming galaxies known at z0, considered a unique local analogue of the first galaxies. The origin of its hard ionizing continuum,…

Chronology of our Galaxy from Gaia colour-magnitude diagram fitting (ChronoGal) II. Unveiling the formation and evolution of the kinematically selected Thick and Thin Discs

Emma Fernández-Alvar, Tomás Ruiz-Lara, Carme Gallart +16

Understanding the formation and evolution of the Milky Way's thin and thick discs is crucial to galaxy formation studies. We derive age and metallicity distributions of the kinemat…

Fundamental relation in isolated galaxies, pairs, and triplets in the local universe

M. Argudo-Fernández, S. Duarte Puertas, S. Verley

In this work, we establish fundamental relations, for the first time, in isolated systems in the local universe (with 0.005z0.080), which can give insight into the unde…
