Determining the outcome of cosmic bubble collisions in full General Relativity
Matthew C. Johnson, Hiranya V. Peiris, Luis Lehner
Cosmic bubble collisions provide an important possible observational window on the dynamics of eternal inflation. In eternal inflation, our observable universe is contained in one…
Intense Electromagnetic Outbursts from Collapsing Hypermassive Neutron Stars
Luis Lehner, Carlos Palenzuela, Steven L. Liebling +2
We study the gravitational collapse of a magnetized neutron star using a novel numerical approach able to capture both the dynamics of the star and the behavior of the surrounding…
Robustness of the Blandford-Znajek mechanism
Carlos Palenzuela, Carles Bona, Luis Lehner +1
The Blandford-Znajek mechanism has long been regarded as a key ingredient in models attempting to explain powerful jets in AGNs, quasars, blazzars etc. In such mechanism, energy is…
Boosting jet power in black hole spacetimes
David Neilsen, Luis Lehner, Carlos Palenzuela +4
The extraction of rotational energy from a spinning black hole via the Blandford-Znajek mechanism has long been understood as an important component in models to explain energetic…
