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…
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…
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 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…
