From Gaia to GaiaNIR: II. A new view of the Milky Way bar
Ó. 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…
Tidally-induced radial migration waves in LMC-like galaxies
Dylan Hebrail, Óscar Jiménez-Arranz, Santi Roca-Fàbrega
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
Ó. 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…
Tidal interaction can stop galactic bars: on the LMC non-rotating bar
Óscar Jiménez-Arranz, Santi Roca-Fàbrega
Context: Using Gaia DR3 data, Jiménez-Arranz et al. (2024a) computed the LMC bar pattern speed using three different methods. One of them suggested that the LMC might be hosting a…
Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry
Gaia Collaboration, P. Panuzzo, T. Mazeh +412
Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…
KRATOS: A large suite of N-body simulations to interpret the stellar kinematics of LMC-like discs
Ó. Jiménez-Arranz, S. Roca-Fàbrega, M. Romero-Gómez +4
We present KRATOS, a comprehensive suite of 28 open access pure N-body simulations of isolated and interacting LMC-like galaxies, to study the formation of substructures in their d…
Gaia Focused Product Release: Sources from Service Interface Function image analysis -- Half a million new sources in omega Centauri
Gaia Collaboration, K. Weingrill, A. Mints +400
Gaia's readout window strategy is challenged by very dense fields in the sky. Therefore, in addition to standard Gaia observations, full Sky Mapper (SM) images were recorded for ni…
Gaia Focused Product Release: Radial velocity time series of long-period variables
Gaia Collaboration, M. Trabucchi, N. Mowlavi +403
The third Gaia Data Release (DR3) provided photometric time series of more than 2 million long-period variable (LPV) candidates. Anticipating the publication of full radial-velocit…
