Modifications to Lorentz invariant dispersion in relatively boosted frames
Uri Jacob, Flavio Mercati, Giovanni Amelino-Camelia +1
We investigate the implications of energy-dependence of the speed of photons, one of the candidate effects of quantum-gravity theories that has been most studied recently, from the…
Inspecting absorption in the spectra of extra-galactic gamma-ray sources for insight into Lorentz invariance violation
Uri Jacob, Tsvi Piran
We examine what the absorbed spectra of extra-galactic TeV gamma-ray sources, such as blazars, would look like in the presence of Lorentz invariance violation (LIV). Pair-productio…
Lorentz-violation-induced arrival delays of cosmological particles
Uri Jacob, Tsvi Piran
We point out that previous studies of possible Lorentz-violating effects in astronomical time-of-flight data did not take into account the entire implications of the universe's cos…
GRBs Neutrinos as a Tool to Explore Quantum Gravity induced Lorentz Violation
Uri Jacob, Tsvi Piran
Lorentz Invariance Violation (LIV) arises in various quantum-gravity theories. As the typical energy for quantum gravity is the Planck mass, , LIV will, most likely, be man…
Embedding the Reissner-Nordstrom spacetime in Euclidean and Minkowski spaces
Uri Jacob, Tsvi Piran
We examine embedding diagrams of hypersurfaces in the Reissner-Nordstrom black hole spacetime. These embedding diagrams serve as useful tools to visualize the geometry of the hyper…
