Capacitance bridge measures light-induced force on a cantilever
What the study found The study reports a tabletop interferometer based on a mechanical cantilever that can measure the radiation force exerted by light. It uses a capacitance bridge to detect very small capacitance changes caused by light-driven motion of the cantilever. Why the authors say this matters The authors say the experiment uses equipment…
Nearby black holes fall into three imaging frequency classes
—
in AstrophysicsWhat the study found Nearby supermassive black hole accretion flows can be grouped into three classes based on whether they become transparent at traditional imaging frequencies, require higher frequencies, or are unlikely to be transparent down to the black hole shadow in the submillimeter band. Why the authors say this matters The study suggests these…
Different interferometer combinations vary in axion dark matter sensitivity
Explore how space-based gravitational wave detectors can detect axion-like dark matter using different time-delay interferometry combinations, achieving sensitivity across a broad mass range.
