The gas-phase mass–metallicity relation of dwarf galaxies across large-scale environments using the CAVITY parent sample

Bahar Bidaran, Salvador Duarte Puertas, Isabel Pérez, A. Zurita et autres

Context. The gas-phase mass–metallicity relation (MZR) of galaxies shows a noticeable break in slope and an increased scatter at low stellar masses, suggesting that the physical processes governing chemical enrichment differ between dwarf and high-mass systems. Dwarf galaxies, in particular, are highly …

Mimicking the large-scale structure of the Local Universe

Manuel Alcázar-Laynez, S. Duarte Puertas, S. Verley, Guillermo Blázquez-Calero et autres

Context. Current observational and simulated large-scale structure (LSS) catalogues often lack consistency in assigning galaxies to specific structures, due to the absence of a universally accepted classification criterion. Aims. With the aim to generate synthetic empirical data for fine-tuning LSS s, as …

The impact of bars on the properties of H ii regions in the TIMER survey

L. Sánchez-Menguiano, Dimitri Alexei Gadotti, A. Zurita, E. Florido et autres

ABSTRACT In this study, we perform a comparative analysis of the properties of the H ii regions located in different areas of barred galaxies, with the aim of investigating the impact of bars on the physical properties of the ionized gas. Based …

Chronology of our Galaxy from Gaia colour-magnitude diagram fitting (ChronoGal)

Tomás Ruiz-Lara, David Mirabal, Carme Gallart, Robert J. J. Grand et autres

The Milky Way’s inner region is dominated by a stellar bar and a boxy-peanut-shaped bulge. However, which stellar populations inhabit the inner Galaxy or how star formation proceeded there is still unknown. The difficulty in studying these stars stems from their location …

Rendezvous in CAVITY: Kinematics and gas properties of an isolated dwarf-dwarf merging pair in a cosmic void region

Bahar Bidaran, Simon B. De Daniloff, Isabel Pérez, A. Zurita et autres

Context. Galaxy mergers are pivotal events in the evolutionary history of galaxies, with their impact believed to be particularly significant in dwarf galaxies due to their low masses. However, these events remain largely underexplored, especially in pristine environments such as voids. Aims. …

The Environmental Quenching Mechanisms of Field Dwarf Galaxies

José A. Benavides, Julio F. Navarro, Laura V. Sales, Isabel Pérez et autres

Abstract Field dwarf galaxies not actively forming stars are relatively rare in the local Universe, but are present in cosmological hydrodynamical simulations. We use the TNG50 simulation to investigate their origin and find that they all result from environmental effects that have …

Galaxy mass-size segregation in the cosmic web from the CAVITY parent sample

Isabel Pérez, Anna Ferré-Mateu, G. Torres-Ríos, A. Zurita et autres

Context. The mass-size relation is a fundamental galaxy scaling relation that is intrinsically linked to galaxy formation and evolution. The physical processes involved in galaxy growth leave their particular imprint on the relation between the stellar or total mass and galaxy size. …
