Ultra-light dark matter may consist of axion-like particles with masses below 10^(-19) eV. Two-photon interactions of these particles affect the polarization of radiation propagating through the dark matter. Coherent oscillations of the Bose condensate of the particles induce periodic changes in the plane of polarisation of emission passing through the condensate. We estimate this effect and analyze MOJAVE VLBA polarization observations of bright downstream features in the parsec-scale jets of active galaxies. Through the non-observation of periodic polarization changes, we are able to constrain the photon coupling of the ultra-light dark-matter axion-like particles at the level of <~ 10^(-12)/GeV for masses between ~5*10^(-23) eV and ~1.2*10^(-21) eV.

  1. Searches for signatures of ultra-light axion dark matter in polarimetry data of the European Pulsar Timing Array

    astro-ph.CO 2024-12 conditional novelty 6.0 of 10

    Analysis of EPTA pulsar polarimetry finds no evidence for ultra-light axion dark matter, sets upper limits on the axion-photon coupling, and attributes a common 2-year-period signal to ionospheric Faraday rotation.

  2. Lensed fast radio bursts as a probe of time-varying gravitational potential induced by wave dark matter

    astro-ph.GA 2024-12 conditional novelty 5.0 of 10

    Wave dark matter halo fluctuations would stretch lensed FRB signals by about 10^-10, a drift that one year of monitoring lensed repeating bursts could detect.

  3. The Lunar Farside Transients and Technology Telescope (LFT3) Mission

    astro-ph.IM 2026-07 conditional novelty 4.0 of 10

    Proposes a $150M-class lunar farside radio telescope (LFT3) to survey 0.1–2700 MHz in the RFI-pristine shielded zone before lunar-orbital interference closes the window.

  4. Probing the Fundamental Nature of Particle Dark Matter

    astro-ph.CO 2026-06 unverdicted novelty 2.0 of 10

    Review summarizing radio searches for WIMP and ALP dark matter with SKA precursors and forecasts for SKA-Low and SKA-Mid telescopes.
