Description
Summary:International audience Ultralight axionlike particles (ALPs) are compelling dark matter candidates because of their potential to resolve small-scale discrepancies between <math display="inline"><mi mathvariant="normal">Λ</mi><mi>CDM</mi></math> predictions and cosmological observations. Axion-photon coupling induces a polarization rotation in linearly polarized photons traveling through an ALP field; thus, as the local ALP dark matter field oscillates in time, distant static polarized sources will appear to oscillate with a frequency proportional to the ALP mass. We use observations of the cosmic microwave background from SPT-3G, the current receiver on the South Pole Telescope, to set upper limits on the value of the axion-photon coupling constant <math display="inline"><msub><mi>g</mi><mrow><mi>ϕ</mi><mi>γ</mi></mrow></msub></math> over the approximate mass range <math display="inline"><msup><mn>10</mn><mrow><mo>-</mo><mn>22</mn></mrow></msup><mi>–</mi><msup><mn>10</mn><mrow><mo>-</mo><mn>19</mn></mrow></msup><mtext> </mtext><mtext> </mtext><mi>eV</mi></math>, corresponding to oscillation periods from 12 hours to 100 days.
