X-Ray Detection of the Galaxy’s Missing Baryons in the Circumgalactic Medium of L* Galaxies

X-Ray Detection of the Galaxy’s Missing Baryons in the Circumgalactic Medium of L* Galaxies

The number of baryons hosted in the disks of galaxies is lower than expected based on the mass of their dark matter halos and the fraction of baryon-to-total matter in the Universe, giving rise to the so-called galaxy missing-baryon problem. The presence of cool circumgalactic matter gravitationally...
