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 +13

The gas-phase mass-metallicity relation (MZR) of galaxies shows a noticeable break in slope and increased scatter at low stellar masses, suggesting that the physical processes gove…

Stellar mass and morphology segregation in pairs and multiplets in the cosmic web

G. Torres-Ríos, S. Verley, I. Pérez +4

In this work, we investigate whether the location of galaxies within the large-scale structures (LSS) of the Universe affects their stellar mass () and morphology. To this…

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

Bahar Bidaran, Simon de Daniloff, Isabel Pérez +17

Galaxy mergers are pivotal events in the evolutionary history of galaxies, with their impact believed to be particularly significant in dwarf galaxies. We report the serendipitous…

The Environmental Quenching Mechanisms of Field Dwarf Galaxies

José A. Benavides, Julio F. Navarro, Laura V. Sales +2

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 t…

The puzzle of isolated and quenched dwarf galaxies in cosmic voids

Bahar Bidaran, Isabel Pérez, Laura Sánchez-Menguiano +12

We report, for the first time, the detection of a sample of quenched and isolated dwarf galaxies (with 8.9 log(M/M) 9.5) in the least dense regi…
