Helicity-dependent corrections to black-hole shadows from the gravitational spin Hall effect
C. A. S. Almeida
Black-hole shadows are purely geometric in the leading-order geometric-optics approximation: their boundary is set by null geodesics and carries no information about the polarizati…

Perturbative solutions for compact objects in (2+1)-dimensional Bopp-Podolsky electrodynamics
R. V. Maluf, J. E. G. Silva, C. A. S. Almeida +1
We investigate the space-time geometry generated by compact objects in (2+1)-dimensional Bopp-Podolsky electrodynamics. Inspired by previous studies where the Bopp-Podolsky field a…
