Search for solar axions produced through the axion-electron coupling using a new GridPix detector at CAST

K. Altenmüller, V. Anastassopoulos, S. Arguedas-Cuendis +61

We present a search for solar axions produced through the axion-electron coupling using data from a novel 7-GridPix detector installed at the CERN Axion Solar Telescope…

A new upper limit on the axion-photon coupling with an extended CAST run with a Xe-based Micromegas detector

CAST Collaboration, K. Altenmüller, V. Anastassopoulos +62

Hypothetical axions provide a compelling explanation for dark matter and could be emitted from the hot solar interior. The CERN Axion Solar Telescope (CAST) has been searching for…

Daily modulations and broadband strategy in axion searches. An application with CAST-CAPP detector

F. Caspers, C. M. Adair, K. Altenmüller +60

It has been previously advocated that the presence of the daily and annual modulations of the axion flux on the Earth's surface may dramatically change the strategy of the axion se…

Atmospheric Temperature anomalies as manifestation of the dark Universe

K. Zioutas, V. Anastassopoulos, A. Argiriou +14

We are investigating the possible origin of small-scale anomalies, like the annual stratospheric temperature anomalies. Unexpectedly within known physics, their observed planetary…

Improved Search for Solar Chameleons with a GridPix Detector at CAST

V. Anastassopoulos, S. Aune, K. Barth +66

We report on a new search for solar chameleons with the CERN Axion Solar Telescope (CAST). A GridPix detector was used to search for soft X-ray photons in the energy range from 200…

aKWISP: investigating short-distance interactions at sub-micron scales

G. Cantatore, V. Anastassopoulos, S. Cetin +8

The sub-micron range in the field of short distance interactions has yet to be opened to experimental investigation, and may well hold the key to understanding al least part of the…

New CAST Limit on the Axion-Photon Interaction

CAST collaboration, V. Anastassopoulos, S. Aune +64

During 2003--2015, the CERN Axion Solar Telescope (CAST) has searched for conversion in the 9 T magnetic field of a refurbished LHC test magnet that can be directed toward…

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…

Axion Searches with Helioscopes and astrophysical signatures for axion(-like) particles

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

The first part reviews the working mechanisms, capabilities and performance of axion helioscopes, including the achieved results so far. The 2nd part is observationally driven. New…

Overlooked astrophysical signatures of axion(-like) particles

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

The working principle of axion helioscopes can be behind unexpected solar X-ray emission, being associated with solar magnetic fields, which become the catalyst. Solar axion signal…
