Abstract
Bulk cone singularities are singularities in boundary two-point functions at points separated by a null geodesic in the bulk, but not in the boundary. In this work, we describe a new type of bulk cone singularities in a family of Vaidya-like spacetimes that are labeled by the radius of the resulting black hole. We find a sharp transition in the causal structure within this family of spacetimes at , the AdS length. In particular, there are bulk cone singularities that do not exist in the case, but appear for . In the case of where such singularities exist, we are able to reproduce the singularities in a CFT calculation using large conformal blocks.
