Masers, which are like lasers that operate in the microwave spectral range, can reliably keep time but have limited accuracy. "The stability of the masers -- one of the best local time scales in ...

The maser, which is like a laser except that it operates in the microwave spectral range, can be used as a type of reliable pendulum with limited accuracy to bridge the downtime of the optical clock.

Additionally, it significantly expands bandwidth and reduces microwave power requirements ... operation across 90 percent of ...

Microwaves comprise one wavelength range which has been pursued with new instrumentation ... microwaves can serve as a surrogate for hard X-ray observations and potentially detect progressive spectral ...

In this situation, an energetic electron produced by the demise of a dark-matter particle could transfer some of its energy to a CMB photon, “distorting the microwave background away from a blackbody, ...
