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…
FASTAR -- II. Semi-resolved evolutionary stellar population models
Ignacio MartÃn-Navarro, Alexandre Vazdekis, Luis Peralta de Arriba +12
Standard evolutionary synthesis models rely on the assumption of a fully sampled stellar initial mass function (IMF). Under this assumption, the age, chemical composition, and IMF…
FASTAR -- I. Continuous and differentiable evolutionary stellar population models
Ignacio MartÃn-Navarro, Alexandre Vazdekis, Luis Peralta de Arriba +11
The development of evolutionary stellar population models is central to interpreting observations of galaxies in terms of astrophysical quantities. Stellar population models must t…
Tracing the dynamical and structural complexity of spiral galaxy centres
Iris Breda, Glenn van de Ven, Sabine Thater +7
The formation of late-type galaxies has traditionally been described via two pathways: one producing pressure-supported classical bulges, the other rotationally supported pseudo-bu…
Glance: A Comprehensive Framework for Galactic Archaeology
Iris Breda, Glenn van de Ven, Sabine Thater +8
A central topic in extragalactic astronomy is understanding the formation and evolutionary histories of galaxies. These systems often comprise multiple structural components with d…
Orbital decomposition of the nuclear regions in the early-type galaxy FCC 47: Unveiling the nuclear cluster origin
Julia Lamprecht, Anja Feldmeier-Krause, Mariya Lyubenova +8
Nuclear star clusters (NSCs) are among the densest stellar systems in the Universe and often coexist with supermassive black holes (SMBHs) at galaxy centres. While SMBH formation h…
