The GECKOS survey: Assembly history of the lenticular galaxy NGC 3957

Yuchen Ding, Marie Martig, Ling Zhu +24

We analyse the assembly history of the edge-on lenticular galaxy NGC 3957 using deep integral-field spectroscopic MUSE data from the GECKOS survey. By applying a dust-corrected Mul…

Bulgeless Evolution And the Rise of Discs (BEARD) I. Physical drivers of the mass-size relation for Milky Way-like galaxies

C. Marrero-de la Rosa, J. Méndez-Abreu, A. de Lorenzo-Cáceres +20

In the standard cold dark matter (CDM) cosmology, the existence of massive pure-disc galaxies remains challenging within the hierarchical framework and is key to understandi…

Bulgeless Evolution And the Rise of Discs (BEARD) III. A numerical simulation view of satellites around Milky-Way analogues

Salvador Cardona-Barrero, Jairo Méndez-Abreu, Adriana de Lorenzo-Cáceres +17

. The existence of massive disc galaxies with little or no bulge challenges conventional cold dark matter model, which typically favours dynamically hot central structure…

Bulgeless Evolution And the Rise of Discs (BEARD) II. The role of mergers in shaping the Milky Way analogues in TNG50

Yetli Rosas-Guevara, Jairo Méndez-Abreu, Adriana de Lorenzo-Cáceres +20

We study the formation and evolution of bulgeless galaxies within the Milky Way-Andromeda analogue sample of the TNG50 simulation. Through kinematic decomposition with Mordor, we i…

Determining star formation histories and age-metallicity relations with convolutional neural networks

Enrique Galceran, Patricia Sánchez-Blázquez, Artemi Camps-Fariña +8

We aim to develop a state-of-the-art tool to infer detailed star formation histories (SFHs) and age-metallicity relations from realistic observational data, while mitigating classi…

The GECKOS Survey: Extraplanar ionised gas in star-forming galaxies from eDIG to galaxy-scale winds

R. Elliott, D. B. Fisher, B. Mazzilli Ciraulo +19

We map the extraplanar gas, with 50-200 pc resolution, in nine star-forming galaxies using Multi-Unit Spectroscopic Explorer (MUSE) observations from the GECKOS VLT Large Pro…

Disc growth and vertical heating of lenticular galaxies in the Fornax cluster

Marie Martig, Francesca Pinna, Jesús Falcón-Barroso +3

We present a detailed analysis of the vertical and radial structure of mono-age stellar populations in three edge-on lenticular galaxies (FCC 153, FCC 170, and FCC 177) in the Forn…

The GECKOS Survey: Resolved, multiphase observations of mass-loading and gas density in the galactic wind of NGC 4666

Barbara Mazzilli Ciraulo, D. B. Fisher, R. Elliott +24

We present a multiphase, resolved study of the galactic wind extending from the nearby starburst galaxy NGC 4666. For this we use VLT/MUSE observations from the GECKOS program and…

Scaling relations at the central regions of nearby galaxies

Patrícia da Silva, R. B. Menezes, T. V. Ricci +3

Scaling relations between galactic parameters represent key pieces of evidence for investigating the processes of galaxy formation and evolution. In most studies, these relations h…

The GECKOS survey: Jeans anisotropic models of edge-on discs uncover the impact of dust and kinematic structures

T. H. Rutherford, A. Fraser-McKelvie, E. Emsellem +17

The central regions of disc galaxies host a rich variety of stellar structures: nuclear discs, bars, bulges, and boxy-peanut (BP) bulges. These components are often difficult to di…

Extreme cloud collisions in nearby barred galaxies

Tutku Kolcu, Mattia C. Sormani, Witold Maciejewski +16

The inner regions of the Milky Way are known to contain an enigmatic population of prominent molecular clouds characterised by extremely broad lines. The physical origin of these '…

The GECKOS Survey: Identifying kinematic sub-structures in edge-on galaxies

A. Fraser-McKelvie, J. van de Sande, D. A. Gadotti +30

The vertical evolution of galactic discs is governed by the sub-structures within them. We examine the diversity of kinematic sub-structure present in the first 12 galaxies observe…

Relatively young thick disks in star-forming late-type galaxies

Natascha Sattler, Francesca Pinna, Sebastien Comerón +4

We trace the evolution of eight edge-on star-forming disk galaxies by analyzing stellar population properties of their thin and thick disks. These galaxies have relatively low stel…

Recovering chemical bimodalities in observed edge-on stellar disks: insights from AURIGA simulations

Francesca Pinna, Robert J. J. Grand, Marie Martig +1

We assessed the ability to recover chemical bimodalities in integral-field spectroscopy (IFS) observations of edge-on galaxies, using 24 Milky Way-mass galaxies from the AURIGA zoo…

Stellar populations and origin of thick disks in AURIGA simulations

Francesca Pinna, Daniel Walo-Martín, Robert J. J. Grand +5

The origin of thick disks and their evolutionary connection with thin disks are still a matter of debate. We provide new insights into this topic by connecting the stellar populati…
