The GAGE survey. I. Deep multi-band stellar variability characterization and automated classification toward Baade's window

Context. Long-term photometric surveys of the Galactic bulge are vital for characterizing its stellar populations and structure, providing a foundation for next-generation facilities. Aims. We present initial results of the GalActic bulGe with plEiadi (GAGE) project, focusing on variable star discovery in Baade's Windo...

Variable stars in Local Group galaxies. VIII. A new look into the dSph galaxy Canes Venatici I

Canes Venatici I (CVnI) is a distant dwarf spheroidal galaxy (dSph) satellite of the Milky Way (MW). Recent estimates of its size and luminosity suggest that it does not belong to the ultra-faint class, but rather is similar to the classical MW dSph satellites. The aim of this work is to explore the variable stars of C...

Variable Stars in Local Group Galaxies IX: Tracing the Complex History of NGC 205

We present the most extensive catalogue of variable stars in NGC 205 to date, based on archival HST/ACS imaging of a single field $\sim 4^\prime$ from the galaxy centre (GO-15902). We detect 1441 RR Lyrae stars (1064 RRab, 363 RRc, and 14 of uncertain mode) and 35 anomalous Cepheids, and measure their periods, amplitud...
