Constraints on the fuzzy dark matter mass using globular clusters in dwarf galaxies from Euclid ERO data
Lisa Besnard, Pierre Boldrini, Paola Di Matteo +2
We constrain the particle mass of the fuzzy dark matter model using globular cluster candidates in dwarf galaxies, from the Euclid Early Release Observations, within the Fornax and…
Galactic tides in the Solar System within a non-axisymmetric Milky Way model adjusted to Gaia data
Alexandre Bougakov, Yassin Rany Khalil, Marc Fouchard +4
Context. Galactic tides are external differential forces acting on extended systems immersed in the Galactic potential. They play a key role in the dynamics of comets in the Oort c…
Unveiling the Milky Way with a Gaia DR3 census of OB-type stars within 2 kpc. I. Tracing local Galactic structure, massive star-forming regions and core-collapse supernova progenitors
Alexis L. Quintana, Kiril Maltsev, Eloisa Poggio +10
O- and B-type stars are young and hot, thereby serving as vital tracers of the star formation and spiral arm structure of the Milky Way. At the dusk of the \textit{Gaia} DR3 era, a…
When bars and spirals conspire: recurrent build-up of the nuclear regions of disc galaxies
Tristan Boin, Sergey Khoperskov, Paola Di Matteo +6
The assembly history of the central regions of disc galaxies is regulated by dynamical processes that trigger gas infall events, leading to active star formation in nuclear stellar…
Bar-induced deflection of open cluster tidal tails
Hanna Parul, Laia Casamiquela, Paola Di Matteo +1
We present a systematic study of how the Galactic bar affects the orientation of tidal tails of open clusters and assess the power of tail morphology to constrain the bar's pattern…
The chemo-dynamical complexity of ω Centauri: different kinematics for different populations
G. Pagnini, P. Bianchini, P. Di Matteo +1
The origin of ω Centauri remains one of the key open problems in stellar dynamics and chemical evolution. Its large abundance spreads and multiple populations suggest a formation h…
Bar Formation During a Gaia-Sausage-Enceladus-like Merger Event
Bin-Hui Chen, Juntai Shen, Paola Di Matteo
Bars are among the most prominent galactic structures, yet their formation mechanisms remain incompletely understood. They can form either internally, via dynamical instabilities,…
