Causality and black holes in spacetimes with a preferred foliation (2016)
Journal Article
Bhattacharyya, J., Colombo, M., & Sotiriou, T. P. (2016). Causality and black holes in spacetimes with a preferred foliation. Classical and Quantum Gravity, 33(23), Article 235003. https://doi.org/10.1088/0264-9381/33/23/235003

© 2016 IOP Publishing Ltd. We develop a framework that facilitates the study of the causal structure of spacetimes with a causally preferred foliation. Such spacetimes may arise as solutions of Lorentz-violating theories, e.g. Horava gravity. Our fra... Read More about Causality and black holes in spacetimes with a preferred foliation.

Evolution and spherical collapse in Einstein-Æther theory and Hořava gravity (2016)
Journal Article
Bhattacharyya, J., Coates, A., Colombo, M., & Sotiriou, T. P. (2016). Evolution and spherical collapse in Einstein-Æther theory and Hořava gravity. Physical Review D, 93(6), Article 64056. https://doi.org/10.1103/PhysRevD.93.064056

We compare the initial value formulation of the low-energy limit of (nonprojectable) Hořava gravity to that of Einstein-æther theory when the æther is assumed to be hypersurface orthogonal at the level of the field equations. This comparison clearly... Read More about Evolution and spherical collapse in Einstein-Æther theory and Hořava gravity.
