We investigate the linear stability of the two known branches of spherically symmetric black
holes in quadratic gravity. We extend previous work on the long-wavelength (Gregory …

The grand canonical ensemble of ad-dimensional Reissner-Nordström black hole space in
a cavity is analyzed in every possible aspect. The analysis starts with the realization of the …

We investigate the role of a specifically warped extra dimension in constructing examples of
higher dimensional spacetimes representing Lorentzian wormholes. The warping chosen is …

This paper exploits the power of the Cayley–Dickson algebra to generate stationary rotating
black hole solutions in one fell swoop. Specifically, we derive the nine-dimensional Myers …

Motivated by understanding the nonlinear gravitational dynamics of spacetimes admitting
stably trapped null geodesics, such as ultracompact objects and black string solutions to …

Recent developments in string theory, such as the AdS/CFT correspondence, have
increased the interest in higher dimensional curved spaces. The Randall-Sundrum model, a …

In this habilitation thesis, I will present the works I have done since my PHD. They are all
related to the study of Einstein equations so I start with a general introduction on the topic …
