Horizonless Spacetimes As Seen by Present and Next-generation Event Horizon Telescope Arrays
We study the capabilities of present and future radio very long baseline interferometry arrays to distinguish black holes from horizonless spacetimes. We consider an example of a horizonless spacetime, obtained by overspinning a regular black hole. Its image is distinct from the image of a Kerr spac...
