ngEHT white paper on Fundamental Physics

Black holes can be studied with gravitational waves, but also with light. After the pioneering Event Horizon Telescope images, the next generation observatories - ngEHT - promise to give us amazing new information on the region close to the horizons of black holes. Vitor Cardoso coordinated (with Ziri Younsi) a white paper, from and for the community, to explore all the beautiful fundamental physics that can be extracted in the future. Stay tuned!
