Unified Deep Learning Approach for Estimating the Metallicities of RR Lyrae Stars Using light curves from Gaia Data Release 3
Lorenzo Monti, Tatiana Muraveva, Alessia Garofalo +2
RR Lyrae stars (RRLs) are old pulsating variables widely used as metallicity tracers due to the correlation between their metal abundances and light curve morphology. With ESA Gaia…
Exploring the Sagittarius stream with RR Lyrae Stars from Gaia Data Release 3
Tatiana Muraveva, Michele Bellazzini, Alessia Garofalo +3
The Sagittarius (Sgr) dwarf spheroidal galaxy is one of the most prominent satellites of the Milky Way (MW). It is currently undergoing tidal disruption, forming an extensive stell…
Constraining Lens Masses in Moderately to Highly Magnified Microlensing Events from Gaia
U. Pylypenko, Ł. Wyrzykowski, P. J. Mikołajczyk +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…
The mass-metallicity relation at z>3 down to M_*= 10^4 M_Sun. A local perspective using the metallicity distribution of RR Lyrae stars
M. Bellazzini, T. Muraveva, A. Garofalo
The mass-metallicity relation (MZR) is a fundamental scale law of galaxies. It is observed to evolve with redshift in unresolved galaxies up to z>6. However, observational constrai…
