Recent works have suggested that the entanglement wedge of Hawking radiation includes an island inside the black hole interior after the Page time. In this talk, I will discuss a concrete way to extract information from the island, by acting only on the radiation. The method makes use of the concept of modular flow, which has been proposed as an useful tool for doing entanglement wedge reconstruction in holography. I will show that the methods works nicely in examples with JT gravity coupled to baths, and also comment on more general situations. The main part of the talk will be based on arXiv:1912.02210.
