The abundance of compact quiescent galaxies since z ~ 0.6

We set out to quantify the number density of quiescent massive compact galaxies at intermediate redshifts. We determine structural parameters based on i-band imaging using the Canada–France–Hawaii Telescope (CFHT) equatorial Sloan Digital Sky Survey (SDSS) Stripe 82 (CS82) survey (∼170 deg2) taking advantage of an exquisite median seeing of ∼0.6 arcsec. We select compact massive (M⋆ > 5 × 1010 M⊙)...
