The 5 pages that link to Missing baryon problem, each with the reason it gives.

• Fast radio burstRelated: Burst dispersion measurements help locate diffuse ionized matter that telescopes cannot easily see.

• Intergalactic mediumRelated: Diffuse intergalactic gas accounts for much of the baryonic matter once difficult to detect.

• Circumgalactic mediumRelated: Diffuse circumgalactic gas accounts for a substantial share of baryons difficult to detect.

• Warm–hot intergalactic mediumRelated: The warm–hot medium is a leading proposed reservoir for the hard-to-detect baryons.

• Extragalactic astronomyRelated: Extragalactic gas surveys help locate ordinary matter outside visible galaxies.
