Search for energetic cosmic axions utilizing terrestrial/celestial magnetic fields / Zioutas, Konstantin (Thessaloniki U.) ; Thompson, D J (NASA, Goddard) ; Paschos, E A (Dortmund U.)
Orbiting $\gamma$-detectors combined with the magnetic field of the Earth or the Sun can work parasitically as cosmic axion telescopes. The relatively short field lengths allow the axion-to-photon conversion to be coherent for $m_{axion} \sim 10^{-4}$ eV, if the axion kinetic energy is above $\sim 500$ keV (Earth's field), or, $\sim 50$ MeV (Sun's field), allowing thus to search for axions from $e^+e^-$ annihilations, from supernova explosions, etc. [...]

A Decommissioned LHC Model Magnet as an Axion Telescope / Zioutas, K. (Thessaloniki U.) ; Aalseth, C.E. (South Carolina U.) ; Abriola, D. (CNEA, Buenos Aires) ; Avignone, F.T., III (South Carolina U.) ; Brodzinski, R.L. (PNL, Richland) ; Collar, J.I. (CERN) ; Creswick, R. (South Carolina U.) ; Di Gregorio, D.E. (CNEA, Buenos Aires) ; Farach, H. (South Carolina U.) ; Gattone, A.O. (CNEA, Buenos Aires) et al.
The 8.4 Tesla, 10 m long transverse magnetic field of a twin aperture LHC bending magnet can be utilized as a macroscopic coherent solar axion-to-photon converter. Numerical calculations show that the integrated time of alignment with the Sun would be 33 days per year with the magnet on a tracking table capable of $\pm 5^o$ in the vertical direction and $\pm 40^o$ in the horizontal direction.

The CAST Experiment : Status and Perspectives / Dafni, T (U. Zaragoza, LFNAE) /CAST
CAST (CERN Axion Solar Telescope) is looking for axions coming from the Sun, using an LHC decommissioned prototype dipole magnet as a converter of axions into detectable x-rays. The experiment started data-taking in 2002 and has used different configurations, keeping the magnet bores under vacuum and using $^4He$ as buffer gas [...]

Thermal analysis and cryogenics of the Baby-IAXO magnet / Silva, H F P (CERN) ; Dudarev, A (CERN) ; Bykovskiy, N (CERN) ; de Sousa, P Borges (CERN) ; ten Kate, H H J (CERN)
Baby-IAXO is a new helioscope, a demonstration version of the proposed full-size IAXO, the International Axions Observatory. It is currently under design and once installed it will search via the Primakoff effect for axions or axion-like particles (ALPs) originating in the Sun. [...]

Observational evidence for gravitationally trapped massive axion(-like) particles / DiLella, L (CERN) ; Zioutas, K (CERN ; Aristotle U., Thessaloniki ; Darmstadt, Tech. Hochsch.)
Several unexpected astrophysical observations can be explained by gravitationally captured massive axions or axion-like particles, which are produced inside the Sun or other stars and are accumulated over cosmic times. Their radiative decay in solar outer space would give rise to a `self-irradiation' of the whole star, providing the time-independent component of the corona heating source (we do not address here the flaring Sun).
