COSMOS: A numerical relativity code specialized for PBH formation
Chul-Moon Yoo, Hirotada Okawa, Albert Escrivà +7
Primordial black holes (PBHs) are black holes generated in the early universe without having gone through stellar evolution. In the standard formation process, PBHs are formed from…
Rotating wormholes in five dimensions with equal angular momenta: large asymmetry regime
Keiya Uemichi, Yasutaka Koga, Daiki Saito +2
We clarify the relationship between rotation and the energy condition for stationary rotating wormhole solutions of the Einstein equations coupled to a phantom field in five-dimens…
Dynamical Formation of Self-Similar Wormholes
Yasutaka Koga, Ryota Maeda, Daiki Saito +1
We study spherically symmetric, self-similar wormhole solutions supported by colliding streams of negative-energy null dust, and their dynamical formation. Under the assumption of…
Dynamical Formation of Charged Wormholes
Yasutaka Koga, Ryota Maeda, Daiki Saito +2
We construct static, spherically symmetric, charged traversable wormhole solutions to the Einstein--Maxwell equations, supported by bidirectional (ingoing and outgoing) null dust w…
