The Canadian Hydrogen Observatory and Radio-transient Detector (CHORD) is a next-generation radio telescope, proposed for construction to start immediately. CHORD is a pan-Canadian project, designed to work with and build on the success of the Canadian Hydrogen Intensity Mapping Experiment (CHIME). It is an ultra-wideband, "large-N, small-D" telescope, consisting of a central array of 512x6-m dishes, supported by a pair of distant outrigger stations, each equipped with CHIME-like cylinders and a 64-dish array. CHORD will measure the distribution of matter over a huge swath of the Universe, detect and localize tens of thousands of Fast RadioBursts (FRBs), and undertake cutting-edge measurements of fundamental physics.

  3. Radio Emission from High-Frequency Gravitational Wave Point Sources

    hep-ph 2026-06 unverdicted novelty 5.0

    Radio telescopes outperform other experiments at detecting high-frequency gravitational waves from primordial black hole mergers and boson clouds through conversion to radio signals in magnetic fields.

  4. Cosmology with HI Intensity Mapping

    astro-ph.CO 2026-07 accept novelty 4.0

    SKAO HI intensity mapping forecasts yield competitive LambdaCDM constraints (e.g. H0 to ~0.3 km/s/Mpc optimistic) via power spectrum, BAO, bispectrum and stacking, complementary to CMB and optical surveys.
