Shadow cast by rotating braneworld black holes with a cosmological
  constant
  In this article, we study the shadow produced by rotating black holes with a
tidal charge in a Randall-Sundrum braneworld model, with a cosmological
constant. We obtain the apparent shape and the corresponding observables for
different values of the tidal charge and the rotation parameter, and we analyze
the influence of the presence of the cosmological constant. We also discuss the
observational prospects for this optical effect.
