Black hole shadows in nonminimally coupled Weyl connection gravity
Cláudio Gomes, Margarida Lima, Francisco S. N. Lobo +1
We study black hole shadows in nonminimally coupled Weyl connection gravity, a metric-affine extension of general relativity in which spacetime is described by a metric and a Weyl…
On Scalar Cosmological Perturbations in Non-Minimally Coupled Weyl Connection Gravity
M. Lima, C. Gomes
We analyze a theory with non-minimal matter-curvature coupling, considering non-metricity properties with a Weyl connection. This model has the advantage of an extra force term whi…
Decay of solutions of the wave equation in cosmological spacetimes -- a numerical analysis
Flavio Rossetti, Alex Vañó-Viñuales
We numerically evolve spherically symmetric solutions to the linear wave equation on some expanding Friedmann-Lemaître-Robertson-Walker (FLRW) spacetimes and study the respective…
Energy bounds and ergoregion instability in Einstein-Maxwell-Scalar field models
Filipe C. Mena, João M. Oliveira
We investigate energy bounds and the stability of stationary asymptotically flat spacetimes with an ergoregion and no future horizon in the context of Einstein-Maxwell-Scalar field…
