In recent years, there has been significant advancement and a notable surge in the exploration of fundamental field in regions with strong gravity. In light of this expanding and evolving community, the New Horizons for Psi School & Workshop: Black Holes and Fundamental Fields has been conceived to facilitate a thorough discourse on this subject. The 5-day hybrid event is scheduled for July 1st to 5th, 2024, in Lisbon. The initial two days will be dedicated to the school component, with the subsequent three days comprising the workshop segment. The event also provides a platform for students to present their posters.
