Pulsar-Stimulated CH Maser Emission Search in the Interstellar Medium
An observational radio-astronomy technique that looks for maser (stimulated) emission from interstellar CH molecules amplified by the photons of a background pulsar, by differencing pulsar-ON and pulsar-OFF phase spectra of the CH Lambda-doublet transitions near 3.3 GHz. It yields CH column densities and cloud-state diagnostics and places upper limits on the pulsar maser amplification factor, demonstrating the feasibility of detecting fast-switching pulsar-stimulated emission in the interstellar medium.

This paper reports the first observational search for pulsed CH (methylidyne radical) maser emission in the interstellar medium potentially stimulated by the radio pulsar PSR J1644-4559, using the ul…
