"A deeper look on thick discs using data from the Spitzer Survey of Stellar Structure in Galaxies (S4G)"

They are most easily detected in close to edge-on galaxies in which they appear as a roughly exponential excess of light which appears a few thin disc scale heights above the midplane. Their origin has been considered mysterious until recently and several formation theories have been proposed.
