Vacuum polarization throughout general subtracted black hole spacetimes
Alejandro Satz, Mirjam Cvetic
We compute the vacuum polarization of a massless minimally co pled scalar field in a background given by a black hole with subtracted geometry. Extending previous results for the h…

Photon Spheres and Sonic Horizons in Black Holes from Supergravity and Other Theories
M. Cvetic, G. W. Gibbons, C. N. Pope
We study closed photon orbits in spherically-symmetric static solutions of supergravity theories, a Horndeski theory, and a theory of quintessence. These orbits lie in what we shal…
