18:23 Phys.org Examining the supermassive black hole in our galaxy

The supermassive black hole (SMBH) at our galaxy's core, Sagittarius A*, is modest in size with only 4.15 million solar-masses. The Event Horizon Telescope (EHT) recently released a dramatic submillimeter image of it as seen illuminated by its glowing environment. Many galaxies have nuclear SMBHs that are a thousand times bigger, for example the nucleus of M87, whose image was taken by the EHT in 2020. But SagA* is relatively close to us, only about twenty-five thousand light-years, and its proximity offers astronomers a unique opportunity to probe the properties of SMBHs.

Detection of weak signals is a crucial step in the verification of physics hypotheses and making breakthroughs in cutting-edge and fundamental physics research. However, if the signals are too weak to measure, they need enhancement. One attractive way to amplify the signals is quantum amplification. The state-of-the-art quantum amplification techniques still have some limitations because they rely on the inherent discrete state transitions of atoms and molecules and therefore lack tunability, usually enhancing only one signal within a narrow range of frequencies.
