Energy Flow of λ in Hořava-Lifshitz Cosmology

Explore a comprehensive lecture on the energy flow of λ in Hořava-Lifshitz cosmology, delivered by Prof. Ewa Czuchry from the Military University of Technology in Warsaw. Delve into the intricacies of Hořava-Lifshitz gravity, a proposed ghost-free and renormalizable quantum gravity model with anisotropic UV-scaling between space and time. Examine the cosmological background analysis of two different formulations of the theory, with a particular focus on the running of the parameter λ with energy. Discover new bounds on cosmological parameters, especially λ, which describes deviation from classical general relativity, derived from an extensive dataset including Cosmic Microwave Background data, supernovae catalogues, Cepheid variable stars, Baryon acoustic oscillations, Cosmic Chronometers, and gamma-ray bursts. Gain insights into how the obtained bounds for λ differ from the value corresponding to Einstein gravity and appear to run with the energies of the data sources in the two discussed cosmological models.
