BPS Fivebrane Stars III: Effective Actions
Emil J. Martinec, Yoav Zigdon
An effective action for NS5-branes coupled to supergravity is used to derive the full 10d form of horizon-free BPS solutions of fivebranes carrying momentum waves, including both t…

Stringy Forces in the Black Hole Interior
Yoav Zigdon
Effective field theories break down inside large black holes on macroscopic scales when tidal forces are string-sized. If is the horizon radius and is the square of the…

Self Gravitating Spinning String Condensates
Jorge E. Santos, Yoav Zigdon
In the context of the black hole/string transition, it is useful to produce Euclidean string backgrounds representing hot and self-gravitating strings. We utilise analytical and nu…
