A New Catalogue of Galactic Red Supergiants for direct detection of episodic mass-loss events

TL;DR

This paper introduces GalRSG, a comprehensive catalogue of 227 Galactic Red Supergiants, designed for monitoring pre-supernova variability and episodic mass-loss events through high-cadence, multi-wavelength observations.

Contribution

The paper presents a new, well-characterized catalogue of Red Supergiants specifically created for studying their mass-loss behavior and pre-supernova activity.

Findings

Catalogue includes 227 Red Supergiants in the Scutum-Crux region.

Enables detection of episodic mass-loss events and variability.

Supports long-term, high-cadence photometric monitoring.

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.
