The 9 pages that link to Dispersion measure, each with the reason it gives.

• Pulsar timingRelated: Frequency-dependent delays from interstellar electrons must be corrected to compare arrival times.

• Fast radio burstRelated: Its unusually large values show that many bursts crossed substantial ionized matter.

• Descriptive statisticsNarrower topic: They complement measures of center by showing how much observations vary.

• Pulsar timing arrayRelated: Changing interstellar dispersion shifts pulse arrival times and must be corrected.

• Faraday rotationRelated: Together with rotation measure, it helps estimate the mean line-of-sight magnetic field.

• Warm–hot intergalactic mediumRelated: Fast radio bursts can use dispersion to probe otherwise invisible ionized gas.

• Shapiro time delayCompared with: Plasma also delays radio signals, but its frequency dependence distinguishes it from the gravitational delay.

• Missing baryon problemRelated: It turns fast radio bursts into probes of otherwise hard-to-see ionized baryons.

• PSR B1937+21Related: Frequency-dependent delays in its radio pulses reveal electrons between the pulsar and Earth.
