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…

Galaxy groups within voids

M. Argudo-Fernández, G. Torres-Ríos, P. Vásquez-Bustos +18

In this work, we aim to identify and characterise a sample of galaxy groups within voids in the local Universe (z\,<\,0.08), taking into account the peculiarities of these vast and…

ALMA CO-CAVITY I. Resolved Molecular Gas in Void Galaxies

D. Espada, S. B. De Daniloff, S. Duarte Puertas +21

The environment plays a key role in galaxy evolution, yet it remains unclear how detailed molecular gas properties and their connection to star formation and stellar content are in…

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…

MeerKAT view of Hickson Compact Groups: II. HI deficiency in the core and surrounding regions

A. Sorgho, L. Verdes-Montenegro, R. Ianjamasimanana +25

Hickson compact groups (HCGs) offer an ideal environment for investigating galaxy transformation as a result of interactions. It has been established that the evolutionary sequence…

MeerKAT view of Hickson Compact Groups:I. Data description and release

R. Ianjamasimanana, L. Verdes-Montenegro, A. Sorgho +25

Context: Hickson Compact Groups (HCGs) are dense gravitationally-bound collections of 4-10 galaxies ideal for studying gas and star formation quenching processes. Aims: We aim to u…
