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…
Constraining Lens Masses in Moderately to Highly Magnified Microlensing Events from Gaia
U. Pylypenko, Å. Wyrzykowski, P. J. MikoÅajczyk +57
Microlensing events provide a unique way to detect and measure the masses of isolated, non-luminous objects, particularly dark stellar remnants. Under certain conditions, it is pos…
AT2021uey: A planetary microlensing event outside the Galactic bulge
M. Ban, P. Voloshyn, R. Adomaviciene +42
We report the analysis of a planetary microlensing event AT2021uey. The event was observed outside the Galactic bulge and was alerted by both space- (Gaia) and ground-based (ZTF an…
