Searching for axion dark matter conversion signals in the magnetic fields around neutron stars
Axion est une particule hypothétique constituant la matière noire. On cherche à la voire quand elle passe dans un champ magnétique fort (entre 2 étoiles à neutron) elle qu'elle se convertie en rayonnement electromagnétique. Plus le champ magnétique est large plus la signature électromagnétique d'Axion est large. Pour ce faire il faut des radiotéléscope très sensible.
C'est pas simple mais on creuse.....

According to theoretical predictions, axion dark matter could be converted into radio frequency electromagnetic radiation when it approaches the strong magnetic fields that surround neutron stars. This radio signature, which would be characterized by an ultranarrow spectral peak at a frequency that depends on the mass of the axion dark matter particle in question, could be detected using high-precision astronomical instruments.
