Abstract Atomic Compton scattering effect significantly contributes to low-energy electronic recoils below its k-shell energy for the direct dark matter detection. Searches on ADM models, photon leptophilic models as well conventional WIMPs background understandings are vitally required clarify effect. We employed relativistic impulse approximation (RIA) together with ab initio Multi-Configurat...

The beaming pattern of thermal annihilation radiation is broader than the beaming pattern produced by isotropic nonthermal electrons and positrons in the jets of radio-emitting active galactic nuclei which Compton scatter photons from an external isotropic radiation field. Thus blueshifted thermal annihilation radiation can provide the dominant contribution to the high-energy radiation spectrum...

We have developed radiation detectors using the new synthetic diamonds. The diamond detector has an advantage for observations of ”low/medium” energy gamma rays as a Compton telescope. The primary advantage of the diamond detector can reduce the photoelectric effect in the low energy range, which is background noise for tracking of the Compton recoil electron. A concept of the Diamond Compton T...

TeV BL Lacertae objects require extreme relativistic bulk motion in the gamma–ray emission region, but at the VLBI scale their radio knots hardly move. The same sources show evidences, in radio, of a structure made of a fast spine plus a slow layer. We propose that this structure exists even at the gamma–ray scale. One component sees the (beamed) radiation produced by the other, and this enhanc...

In this article we show with the help of two examples how Compton spectroscopy may be used to study the effect of chemical bonding in materials as diverse as a molecular crystal and a high temperature superconductor. Compton spectroscopy has a long history as an investigative method in condensed matter physics and in fact the realisation that the Compton profile is sensitive to the effects of c...

Modified dispersion relations(MDRs) as a manifestation of Lorentz invariance violation, have been appeared in alternative approaches to quantum gravity problem. Loop quantum gravity is one of these approaches which evidently requires modification of dispersion relations. These MDRs will affect the usual formulation of the Compton effect. The purpose of this letter is to incorporate the effects ...
