Imaging topological solitons: The microstructure behind the shadow
Pierre Heidmann, Ibrahima Bah, Emanuele Berti
Abstract
The authors study photon geodesics in the gravitational background generated by smooth horizonless topological solitons with the same large distance behaviour as neutral non-rotating black holes. They show that incoming photons experience very high redshift, inducing phenomenological horizon-like behaviors from the point of view of photon scattering. Thus, they provide a compelling case for real-world gravitational solitons and topological alternatives to black holes.
