The Dark Universe is not invisible

K. Zioutas, V. Anastassopoulos, A. Argiriou +18

Dark matter (DM) comes from long-range gravitational observations, and it is considered as something that does not interact with ordinary matter or emits light. However, also on mu…

The 11-years solar cycle as the manifestation of the dark Universe

K. Zioutas, M. Tsagri, Y. K. Semertzidis +3

The solar luminosity in the visible changes at the 10-3 level, following an 11 years period. In X-rays, which should not be there, the amplitude varies 100000 times stronger, makin…

Solar flares as harbinger of new physics

K. Zioutas, M. Tsagri, Y. Semertzidis +4

This work provides additional evidence on the involvement of exotic particles like axions and/or other WISPs, following recent measurements during the quietest Sun and flaring Sun.…

Signatures for Solar Axions/WISPs

Konstantin Zioutas, Theodoros Vafeiadis, Mary Tsagri +4

Standard solar physics cannot account for the X-ray emission and other puzzles, the most striking example being the solar corona mystery. The corona temperature rise above the non-…

Solar X-rays from Axions: Rest-Mass Dependent Signatures

Konstantin Zioutas, Mary Tsagri, Yannis Semertzidis +4

The spectral shape of solar X-rays is a power law. The more active the Sun is, the less steep the distribution. This behaviour can be explained by axion regeneration to X-rays occu…
