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,…
A new Gaia census of OB associations within 1 kpc
Alexis L. Quintana, Nicholas J. Wright, Lilly A. Kormann +6
OB associations are primordial tracers of star formation and Galactic structure. Originally defined about 80 years ago, their historical membership lists have been superseded thank…
Fuzzy dark matter dynamical friction: stalling of globular clusters induced by dynamical heatings
Adrian Szpilfidel, Pierre Boldrini, Jo Bovy +1
We present a new implementation of fuzzy dark matter (FDM) dynamical friction within the galpy framework, enabling orbital integrations of globular clusters (GCs) across a broad ra…
Chemical decoding of kinematic substructures in the Galactic halo
A. Mori, P. Di Matteo, S. Salvadori +4
In the hierarchical assembly framework, the accretion history of the Milky Way is crucial to understand its evolution. However, in massive mergers, integrals of motion are not stri…
Evidence of Gaia Enceladus experiencing at least two passages around the Milky Way
Ása Skúladóttir, Heitor Ernandes, Diane K. Feuillet +4
One of the major recent breakthroughs has been the discovery of the last Major Merger to happen in the history of the Milky Way. Around 10 Gyr ago the galaxy Gaia Enceladus, with e…
Turbulent gas-rich discs at high redshift: origin of thick stellar discs through 3D 'baryon sloshing'
Joss Bland-Hawthorn, Thor Tepper-Garcia, Oscar Agertz +8
In response to recent observations from JWST and ALMA, we explore a new class of dynamically self-consistent models using our AGAMA/Ramses hydrodynamic N-body framework (Nexus) tha…
Chemical Abundances in the Nuclear Star Cluster of the Milky Way: alpha-Element Trends and Their Similarities with the Inner Bulge
N. Ryde, G. Nandakumar, M. Schultheis +15
A chemical characterization of the Galactic Center is essential for understanding its formation and structural evolution. Trends of alpha-elements, such as Mg, Si, and Ca, serve as…
Rediscovering the Milky Way with orbit superposition approach and APOGEE data I. Method validation
Sergey Khoperskov, Glenn van de Ven, Matthias Steinmetz +9
We introduce a novel orbit superposition method designed to reconstruct the stellar density structure, kinematics, and chemical abundance distribution of the entire Milky Way by le…
The disc origin of the Milky Way bulge: On the high velocity dispersion of metal-rich stars at low latitude
Tristan Boin, Paola Di Matteo, Sergey Khoperskov +5
Previous studies of the chemo-kinematic properties of stars in the Galactic bulge have revealed a puzzling trend. Along the bulge minor axis, and close to the Galactic plane, metal…
Timing the Milky Way bar formation and the accompanying radial migration episode
Misha Haywood, Sergey Khoperskov, Valeria Cerqui +3
We derive the metallicity profile of the Milky Way low- disc population from 2 to 20 kpc from the Galactic centre in 1 Gyr age bins using the astroNN catalogue, and show that it…
Metallicity distributions of halo stars: do they trace the Galactic accretion history?
Alice Mori, Paola Di Matteo, Stefania Salvadori +3
The standard cosmological scenario predicts a hierarchical formation for galaxies. Many substructures were found in the Galactic halo, identified as clumps in kinematic spaces, lik…
Charting the Galactic acceleration field II. A global mass model of the Milky Way from the STREAMFINDER Atlas of Stellar Streams detected in Gaia DR3

Bars and boxy/peanut bulges in thin and thick discs III. Boxy/peanut bulge formation and evolution in presence of thick discs
Soumavo Ghosh, Francesca Fragkoudi, Paola Di Matteo +1
Boxy/peanut (b/p) bulges, the vertically extended inner parts of bars, are ubiquitous in barred galaxies in the local Universe, including our own Milky Way. At the same time, a maj…
Looking for a needle in a haystack: Measuring the length of a stellar bar
Soumavo Ghosh, Paola Di Matteo
One of the challenges related to stellar bars is to accurately determine the length of the bar in a disc galaxy. In the literature, a wide variety of methods have been employed to…
Stragglers of the thick disc
