Compton light pressure and spectral imprint of relic radiation on cosmic electrons
نویسنده
چکیده
A fully relativistic/QED theory of particle motion damping by light pressure of an isotropic, in particular relic, radiation yields analytic results for the momentum decay of an electron over entire span of energies in the Universe. Using a Fokker-Planck-like equation, the evolution of initial extremely-high-T electron distribution to low-energy spectral line is analytically obtained for momentum span over tens orders of magnitude. A strong imprint of low-T relic radiation on highenergy spectral distribution transpires via formation of “frozen non-equilibrium” state of electrons in current epoch, and possible existence of narrow spectral lines as remnants of past high-T sources.

Light pressure of isotropic radiation from relic to extreme relativistic temperatures
A fully relativistic/QED theory of light pressure of an isotropic, in particular relic, radiation yields analytic results in the momentum decay of an electron over entire span of energies in the universe.

متن کاملExtreme Ultraviolet Emission from Clusters of Galaxies: Inverse Compton Radiation from a Relic Population of Cosmic Ray Electrons?
We suggest that the luminous extreme ultraviolet (EUV) emission which has been detected recently from clusters of galaxies is Inverse Compton (IC) scattering of Cosmic Microwave Background (CMB) radiation by low energy cosmic ray electrons in the intracluster medium. The cosmic ray electrons would have Lorentz factors of γ ∼ 300, and would lose energy primarily by emitting EUV radiation. These ...
متن کاملGravity, Relic Coherent Gravitons and Optical Chaos
We discuss the production of massive relic coherent gravitons in a particular class of f(R) gravity, which arises from string theory, and their possible imprint in the Cosmic Microwave Background. In fact, in the very early Universe, these relic gravitons could have acted as slow gravity waves. They may have then acted to focus the geodesics of radiation and matter. Therefore, their imprint on ...
متن کاملMultiwavelength study of Cygnus A II. X-ray inverse-Compton emission from a relic counterjet and implications for jet duty-cycles
The duty-cycle of powerful radio galaxies and quasars such as the prototype Cygnus A is poorly understood. X-ray observations of inverse-Compton scattered Cosmic Microwave Background (ICCMB) photons probe lower Lorentz-factor particles than radio observations of synchrotron emission and thus potentially reveal a more aged population. Comparative studies of the nearer and further lobes, separate...
متن کاملIs the diffuse Gamma Background Radiation generated by Galactic Cosmic Rays?
We explore the possibility that the diffuse gamma-ray background radiation (GBR) at high galactic latitudes could be dominated by inverse Compton scattering of cosmic ray (CR) electrons on the cosmic microwave background radiation and on starlight from our own galaxy. Assuming that the mechanisms accelerating galactic CR hadrons and electrons are the same, we derive simple and successful relati...
