Optical Spectrum of Main‐, Inter‐, and Off‐Pulse Emission from the Crab Pulsar
Optical Spectrum of Main‐, Inter‐, and Off‐Pulse Emission from the Crab Pulsar
A dedicated stroboscopic device was used to obtain optical spectra of the Crab pulsar main pulse and interpulse as well as the spectrum of the underlying nebula when the pulsar is turned off. Since the nebular emission is very inhomogeneous, our ability to effectively subtract the nebular background signal is …
