Hi intensity mapping
WebMay 11, 2024 · The field of neutral hydrogen (HI) intensity mapping (IM) is still maturing, however early attempts are already systematics limited. One such systematic limitation is 1/ f noise, which largely originates within the instrumentation and manifests as multiplicative gain fluctuations.
