Description
Light bosons such as the QCD axion are leading dark matter candidates, with photon couplings enabling both laboratory and astrophysical searches. I will highlight new cavity-based experiments, in particular FLASH, which makes use of high-$Q$ resonators and quantum sensors to open previously inaccessible parameter space and even probe high-frequency gravitational waves. Complementing these efforts, I will present Green Bank Telescope searches for transient radio signals from axion substructures, targeting $m_a \sim 33$–$42~\mu$eV with high spectral resolution. Together, these approaches illustrate how precision cavities and astrophysical observations provide powerful and complementary paths to light up the dark Universe.
