Конверсия аксионов Тёмной Материи в фотоны в магнитосфере нейтронных звёзд. // Пширков М.С. Попов С.Б.
A new method is suggested to search for axions constituting Dark Matter that utilizes observations of neutron stars (NS) in radio-frequency region. It uses the conversion of axions to photons in strong magnetic fields of NS. The observations of Magnificent Seven objects are proposed. Whether the conversion takes place, the radio spectrum of the object would have a very distinctive feature - a narrow spike at a frequency corresponding to the rest mass of the axions. For example, if the coupling constant of photon-axion interaction is GeV and the density of DM axions is , then the flux density of excess signal for axions with rest mass of eV will be as large as several tenth of Jy at the frequency 240 MHz in the bandwidth 0.5 MHz.
