Chiral effects in astrophysics and cosmology

Axions in Astrophysics and Cosmology*

High-Energy Astrophysics and Cosmology

Interfaces between high-energy physics, astrophysics and cosmology are reviewed, with particular emphasis on the important roles played by high-energy cosmic-ray physics. These include the understanding of atmospheric neutrinos, the search for massive cold dark matter particles and possible tests of models of quantum gravity. In return, experiments at the LHC may be useful for refining models o...

Chaotic Phenomena in Astrophysics and Cosmology

Chaos is a typical property of many-dimensional nonlinear systems. Its role it revealed in various problems of astrophysics and cosmology. Chaos made to revise the two-hundred year old views on the evolution of Solar system. Theory of interstellar matter, dynamics of star clusters and galaxies at present cannot be considered without chaotic effects. Astronomical topics themselves had remarkable...

Neutrino-photon reactions in astrophysics and cosmology

At energies above the threshold for W production the process νγ → lW is competive with νν scattering at the same center of mass energies. In a cosmological setting, absorption of ultra high energy neutrinos by the microwave photon background is comparable to absorption by the neutrino background. In passing through matter, the process ν → lW will occur in the coulomb field of nuclei. For iron, ...

Braneworld Black Holes in Cosmology and Astrophysics

The braneworld description of our universe entails a large extra dimension and a fundamental scale of gravity that might be lower by several orders of magnitude compared to the Planck scale. An interesting consequence of the braneworld scenario is in the nature of spherically symmetric vacuum solutions to the brane gravitational field equations which could represent black holes with properties ...
