Characterisation of the Clouds' young stellar Bridge using Gaia DR3
Marie Schölch, Ãscar Jiménez-Arranz, Mercè Romero-Gómez +1
The interaction between the LMC and SMC (the Clouds) has resulted in prominent tidal features, including an extended bridge of gas and stars connecting the two galaxies. This Bridg…
From Gaia to GaiaNIR: II. A new view of the Milky Way bar
Ã. Jiménez-Arranz, M. Schölch, S. Khanna +9
The Milky Way (MW) hosts a central bar whose pattern speed, orientation, and length remain uncertain, largely due to observational biases and selection effects, despite the transfo…
From Gaia to GaiaNIR: I. Probing dark matter halos in globular clusters
I. Henum, D. Hobbs, Ã. Jiménez-Arranz +2
The proposed GaiaNIR mission would extend Gaia's astrometric capabilities into the near-infrared, improving astrometric precision and enabling observations in heavily dust-obscured…
Tidally-induced radial migration waves in LMC-like galaxies
Dylan Hebrail, Ãscar Jiménez-Arranz, Santi Roca-Fà brega
Stellar radial migration has predominantly been examined in isolated disc galaxies where non-axisymmetric structures drive the process. By contrast, while tidal interactions are kn…
Beyond the Clouds: S3 as the most distant extended Milky Way stream, not of LMC origin
Ã. Jiménez-Arranz, S. Lilleengen, M. S. Petersen
Context: While the LMC's influence on MW stellar streams has been extensively studied, streams associated with the Clouds have received far less attention. Beyond the Magellanic St…
Asymmetries in the LMC velocity maps
Marie Schölch, Ãscar Jiménez-Arranz, Mercè Romero-Gómez +4
The analysis of precise Gaia DR3 astrometry in the LMC region has revealed asymmetric patterns in the bar quadrupole and the disc outskirts of the LMC in-plane velocity maps. We ai…
