Superdense Massive Galaxies in the Nearby Universe
At high-z the most superdense massive galaxies are supposed to be the result of gas-rich mergers resulting in compact remnant. After this, dry mergers are expected to be the mechanism that moves these very massive galaxies towards the current stellar mass size relation. Within these merging scenarios, a non-negligible fraction (1-10%) of these
