A Proposal to Search for Transparent Hidden Matter Using Optical Scintillation
Résumé
It is proposed to search for scintillation of extragalactic sourcesthrough the last unknown baryonic structures.Appropriate observation of the scintillation processdescribed here should allow one to detect column densitystochastic variations in cool Galactic molecular clouds of order of$\sim 3\times 10^{-5}\,\mathrm{g/cm^2}$ -- that is$10^{19}\,\mathrm{molecules/cm^2}$ --per $\sim 10\,000\,\mathrm{km}$ transverse distance.
