A New Catalogue of Galactic Red Supergiants for direct detection of episodic mass-loss events
arXiv:2603.15133
Abstract
We present GalRSG, a new catalogue of 227 Galactic Red Supergiants in the Scutum-Crux region, which provides a nearly coeval and co-distant sample, target of a long-term, panchromatic, high-cadence photometric monitoring campaign aimed at detecting pre-supernova variability and luminous eruptively driven mass-loss events.
