Scientists May Finally Have "Seen" Dark Matter

There is an asymmetry between the mass of the electric charges, for example proton and electron, can understood by the asymmetrical Planck Distribution Law. This temperature dependent energy distribution is asymmetric around the maximum intensity, where the annihilation of matter and antimatter is a high probability event. The asymmetric sides are creating different frequencies of electromagnet...

Probing dark matter with X–ray binaries

Low-mass X-ray binaries (LMXBs), which occur in old stellar populations, have velocities exceeding those of their parent distribution by at least 20 km s. This makes them ideal probes for dark matter, in particular in dwarf spheroidals (dSph), where the LMXBs should penetrate well outside the visible galaxy. We argue that the most likely explanation of the observation of LMXBs in the Sculptor d...

Gamma-ray Bursts and Dark Matter -a Joint Origin ?

Two of the most fascinating problems in astrophysics and cosmology today are the origin and nature of the dark matter (DM) and the sources and mechanisms behind the so-called gamma-ray bursts (GRB). The presence of non-luminous, gravitationally interacting matter was inferred in the earlier part of this century when the dynamics of groups of galaxies did not agree with the predictions based on ...

Dark matter annihilation into γ−ray line generated by anomalies

We study the phenomenology of a UX(1) extension of the Standard Model where the SM particles are not charged under the new abelian group. The Green-Schwarz mechanism insures that the model is anomaly free. The erstwhile invisible dark gauge field X , even if produced with difficulty at the LHC has however a clear signature in gamma-ray telescopes. We investigate what BSM scale (which can be int...
