Title:Sub-kiloparsec view of superdense compact galaxies in nearby galaxy clusters Abstract: Massive galaxies at z>2 were a factor of 4 smaller than their present-day local counterparts. In the nearby universe (z<0.2), these galaxies are rare and relatively young. Recent works have suggested that nearby cluster of galaxies have significant fraction of massive compact galaxies, which are are old and intriguingly, are not detected in large surveys. In this contribution we present preliminary analysis of the structural parameters of massive compact galaxies in one galaxy cluster based on high resolution, near diffraction limited images obtained with GeMS and GSAOI.
