Bulk-cone singularities and echoes from AdS exotic compact objects
Heng-Yu Chen, Yasuaki Hikida, Yasutaka Koga
The region near a black hole horizon may be modified by quantum gravity effects that resolve the singularity. Such geometry may be represented by an exotic compact object. Because…

AdS gravastar and its signatures from dual conformal field theory
Heng-Yu Chen, Yasuaki Hikida, Yasutaka Koga
Quantum gravity effects are expected to resolve the black hole singularity and the effects may deform the region near but outside the horizon. Applying AdS/CFT correspondence, we s…
