The baryon census in a multiphase intergalactic medium: 30% of the baryons may still be missing

JM Shull, BD Smith, CW Danforth - The Astrophysical Journal, 2012 - iopscience.iop.org
Although galaxies, groups, and clusters contain∼ 10% of the baryons, many more reside in
the photoionized and shocked-heated intergalactic medium (IGM) and in the circumgalactic …
