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…
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…
CAVITY: Calar Alto Void Integral-field Treasury surveY. I. First public data release
Rubén García-Benito, Andoni Jiménez, Laura Sánchez-Menguiano +40
The Calar Alto Void Integral-field Treasury surveY (CAVITY) is a legacy project aimed at characterising the population of galaxies inhabiting voids, which are the most under-dense…
Are early-type galaxies quenched by present-day environment? A study of dwarfs in the Fornax Cluster
Romero-Gómez, J., Reynier F. Peletier +2
Galaxies undergo processes throughout their lifetimes that ultimately lead to the expulsion of the gas and the cessation of the star-forming activity. This phenomenon commonly know…
Enhanced Destruction of Cluster Satellites by Major Mergers
Kyung Lin Dong, Rory Smith, Jihye Shin +1
Using a set of clusters in dark matter only cosmological simulations, we study the consequences of merging of clusters and groups of galaxies (with mass ratio larger than 5:1) to i…
