Abstract Electromagnetic resonant systems, such as cavities and LC circuits, are widely used to detect ultralight boson dark matter high-frequency gravitational waves. However, the narrow bandwidth of single-mode resonators necessitates multiple scan steps cover broad frequency ranges. By incorporating a network auxiliary modes via beam-splitter-type non-degenerate parametric couplings, we enable broadband detection with an effective each matching order frequency, while maintaining strong...
The Event Horizon Telescope (EHT) has revolutionized our ability to study black holes by providing unprecedented spatial resolution and unveiling horizon-scale details. With advancements leading the next-generation EHT, there is potential probe even deeper into hole's dark region, especially inner shadow characterized low-intensity foreground emissions from jet, thanks a significant enhancement in dynamic range two orders of magnitude. We demonstrate how such enhanced observations could...
