Probing dynamics of extreme galaxies I. Dark matter content in ultra-diffuse galaxies

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…

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

Fossil Groups Origins III. Characterization of the sample and observational properties of fossil systems
S. Zarattini, R. Barrena, M. Girardi +15
(Abridged) Fossil systems are group- or cluster-sized objects whose luminosity is dominated by a very massive central galaxy. In the current cold dark matter scenario, these object…
