Probing dynamics of extreme galaxies I. Dark matter content in ultra-diffuse galaxies
Filippo Bouchè, Chiara Buttitta, Saboura Zamani +6
We investigate the internal structure of two galaxies from the LEWIS sample: the ultra-diffuse galaxy UDG-1 and the extended dwarf LSB-6. Both show coherent stellar rotation combin…
The onset of stellar bars at Cosmic Noon. Bar-driven quenching and AGN co-evolution in a mature disc galaxy
Luca Costantin, Lorenzo Morelli, Cristina Cabello +15
Observations with the JWST revealed an unexpected abundance of barred galaxies at Cosmic Noon. However, the physical properties of these early bars are almost unconstrained, as it…
Looking into the faintEst WIth MUSE (LEWIS): Exploring the nature of ultra-diffuse galaxies in the Hydra-I cluster. VI. A star-forming UDG in Hydra I: a rare UDG or a transition phase?
Luca Rossi, Chiara Buttitta, Goran Doll +21
This paper presents a detailed analysis of a gas-rich star-forming ultra-diffuse galaxy (UDG) as part of the ESO Large Programme 'Looking into the faintEst WIth MUSE (LEWIS)'. Amon…
Advancing the detection of low surface brightness galaxies. I. ATTILA: multi-tAsking deTecTIon tool for Lsb gAlaxies
E. Borsato, F. Fonzo, N. Bellucco +15
Context. Ultra-diffuse galaxies (UDGs) lie at the extreme end of the size-luminosity distribution of low surface-brightness (LSB) galaxies. Their detection and characterization req…
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…
Morpho-kinematic properties of field S0 bulges in the CALIFA survey
J. Mendez-Abreu, J. A. L. Aguerri, J. Falcon-Barroso +22
We study a sample of 28 S0 galaxies extracted from the integral-field spectroscopic (IFS) survey CALIFA. We combine an accurate two-dimensional (2D) multi-component photometric dec…
No evidence for small disk-like bulges in a sample of late-type spirals
L. Costantin, J. Méndez-Abreu, E. M. Corsini +4
About 20% of low-redshift galaxies are late-type spirals with a small or no bulge component. Although they are the simplest disk galaxies in terms of structure and dynamics, the ro…
Fossil Group Origins VII. Galaxy substructures in fossil systems
S. Zarattini, M. Girardi, J. A. L. Aguerri +9
Fossil groups are expected to be the final product of galaxy merging within galaxy groups. In simulations, they are predicted to assemble their mass at high redshift. This early fo…
Study of the stellar population properties in the discs of ten spiral galaxies
L. Morelli, E. M. Corsini, A. Pizzella +3
We investigated the properties of the stellar populations in the discs of a sample of ten spiral galaxies. Our analysis focused on the galaxy region where the disc contributes more…
Counter-Rotation in Disk Galaxies
E. M. Corsini
Counter-rotating galaxies host two components rotating in opposite directions with respect to each other. The kinematic and morphological properties of lenticulars and spirals host…
Dissecting Kinematics and Stellar Populations of Counter-Rotating Galaxies with 2-Dimensional Spectroscopy
L. Coccato, L. Morelli, A. Pizzella +3
We present a spectral decomposition technique and its applications to a sample of galaxies hosting large-scale counter-rotating stellar disks. Our spectral decomposition technique…
Peanut-shaped bulges in face-on disk galaxies
J. Mendez-Abreu, E. M. Corsini, V. P. Debattista +3
We present high resolution absorption-line spectroscopy of 3 face-on galaxies, NGC 98, NGC 600, and NGC 1703 with the aim of searching for box/peanut (B/P)-shaped bulges. These obs…
