20 Searching for axion dark matter with the MeerKAT Radio Telescope

Axions provide a natural and well-motivated dark matter candidate, with the capability to convert directly to photons in the presence of an electromagnetic field. A particularly compelling observational target is the conversion of dark matter axions into photons in the magnetospheres of highly magnetised neutron stars, which is expected to produce a narrow spectral peak centred at the frequency of the axion mass. From 10 hrs MeerKAT radio telescope observations of the isolated neutron star J0806.4-4123 we obtain flux spectra in the frequency range 769-1051 MHz, finding no evidence of this phenomenon. We therefore constrain the Primakoff coupling of axion dark matter, $g_{a\gamma\gamma}\lesssim 6 \times 10^{-11}/GeV to 95% C.L., in the mass range 3.18-4.35 µeV. This result serves the strongest constraint in the mass range 4.2 - 4.35 µeV.

29 Gravitational Wave Burst from Axion Clumps and Possible Dark Fluxes

Abstract: The axion objects such as axion mini-clusters and axion clouds around spinning black holes induce parametric resonances of electromagnetic waves through the axion-photon interaction. In particular, it has been known that the resonances from the axion with the mass around mueV may explain the observed fast radio bursts (FRBs). Here we argue that similar bursts of high-frequency gravitational waves, which we call the fast gravitational-wave bursts (FGBs), are generated from axion clumps with the presence of gravitational Chern-Simons coupling. The typical frequency is half of the axion mass, which in general can range from kHz to GHz. We also comment on the light dark matter flux through several mechanisms from accreting black holes. Future detections of FGBs together with the observed FRBs are expected to provide more evidence for the axion.
