XP-TEAL: Gaia XP Tool for Emission and Absorption Lines II. Gaia-HELIX catalogue of H emitters in Gaia BP/RP spectra

S. Malhotra, M. Weiler, F. Anders +9

Context: With Gaia's third Data Release (DR3), low-resolution BP/RP (XP) spectra became available for more than 219 million sources. In previous work, we developed a fast method fo…

The high-altitude, inner-disc, and chemically peculiar open cluster UBC 1052

Judit Donada, Laia Casamiquela, Friedrich Anders +8

Out of all the discovered open clusters (OCs) that are located in the inner part of the Galaxy, only a small fraction has been observed with high-resolution spectroscopy. An intrig…

Asymmetries in the LMC velocity maps

Marie Schölch, Óscar 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…
