Magnetic field geometry in rotating wormhole spacetimes
Milos Ertola Urtubey, Daniela Pérez
If a black hole is immersed in a magnetosphere,its rotational energy can be transferred to the electromagnetic field and escape as a Poynting flux to infinity. This process of extr…

Gravitational entropy in black hole transformations
Alan Alejandro Pánuco Liñán, Daniela Pérez, Carlos Luna +1
There are several reasons to support the idea that entropy might be associated to gravity itself. In the absence of a quantum theory of gravity, classical estimators for the gravit…

Outgoing electromagnetic flux from rotating wormholes
Milos Ertola Urtubey, Daniela Pérez, Gustavo Esteban Romero
We show for the first time that rotating wormholes are capable of emitting a Poynting flux in the process of accreting magnetized matter. To this end, we analyze the Damour-Soloduk…
