On the regularity of deformed extremal horizons
Francesco Di Filippo, Shinji Mukohyama, José M. M. Senovilla
It has recently been argued that extremal black holes can act as amplifiers of new physics, due to horizon instabilities that enhance the effects of ultraviolet corrections. In thi…
Dust collapse and horizon formation in Quadratic Gravity
Luca Buoninfante, Francesco Di Filippo, Ivan Kolář +1
Quadratic Gravity supplements the Einstein-Hilbert action by terms quadratic in the spacetime curvature. This leads to a rich phase space of static, compact gravitating objects inc…
A connection between regular black holes and horizonless ultracompact stars
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +1
We illustrate that regular black holes and horizonless stars, typically considered as quite distinct families of black hole mimickers, are intimately intertwined. We show that any…
On the inner horizon instability of non-singular black holes
Francesco Di Filippo, Raúl Carballo-Rubio, Stefano Liberati +2
Regular black holes represent a conservative model in which the classical singularity is replaced by a non-singular core without necessarily modifying the spacetime outside the tra…
On the assumptions leading to the information loss paradox
Luca Buoninfante, Francesco Di Filippo, Shinji Mukohyama
The information loss paradox is usually stated as an incompatibility between general relativity and quantum mechanics. However, the assumptions leading to the problem are often ove…
Non-uniqueness of massless transverse-traceless graviton
Katsuki Aoki, Francesco Di Filippo, Shinji Mukohyama
We study a theory of minimally modified gravity called cuscuton/VCDM that propagates only two gravitational degrees of freedom. Despite being apparently different from general rela…
