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 Sun and its Planets as detectors for invisible matter
Sergio Bertolucci, Konstantin Zioutas, Sebastian Hofmann +1
Gravitational lensing of invisible streaming matter towards the Sun could be the explanation of the puzzling solar flares and the unexplained solar emission in the EUV. Assuming th…
A chameleon helioscope
Keith Baker, Axel Lindner, Amol Upadhye +1
Chameleon particles, which could explain dark energy, are in many ways similar to axions, suggesting that an axion helioscope can be used for chameleon detection. The distinguishin…
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 Chameleons
Philippe Brax, Konstantin Zioutas
We analyse the creation of chameleons deep inside the sun and their subsequent conversion to photons near the magnetised surface of the sun. We find that the spectrum of the regene…
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…
