Photon-axion conversion in Active Galactic Nuclei?
Nicola Bassan, Marco Roncadelli
Axion-Like Particles (ALPs) are the focus of intense current research. We analyze photon-ALP conversion in the context of relativistic jet models of Active Galactic Nuclei (AGN) fo…
Discovery of underground argon with low level of radioactive 39Ar and possible applications to WIMP dark matter detectors
C. Galbiati, R. Purtschert
We report on the first measurement of 39Ar in argon from underground natural gas reservoirs. The gas stored in the US National Helium Reserve was found to contain a low level of 39…
