Dark sectors broadly denote explorations of new physics beyond the Standard Model. Several particularly promising venues have been identified and are actively pursued by the astro-particle physics community within recent years, including topics related to axions and axion-like particles, neutrinos, black holes and gravitational waves. The goal of the conference is to bring together experts from these distinct areas in a timely opportunity, leveraging recent advances in the fields, to explore new ideas and bring into focus synergistic grounds for future collaborative research directions.
