Self-gravitating electromagnetic waves in the dark bubble model
Ulf Danielsson, Daniel Panizo, Vincent Van Hemelryck
We construct embeddings of gravitational and electromagnetic waves in the dark bubble scenario using pp-wave geometries in AdS5, motivated by the fact that pp-wave spacetimes often…

Experimental tests of dark bubble cosmology
Ulf Danielsson, Daniel Panizo
In this paper we use -corrections to the -brane action to obtain a non-zero and positive cosmological constant in the induced cosmology living on the dark bubble. Its…

Shedding light on dark bubble cosmology
Ivano Basile, Ulf Danielsson, Suvendu Giri +1
Dark bubble cosmology is an alternative paradigm to compactification, which can circumvent issues of moduli stabilization and scale separation. In this paper we investigate how ele…
