Descripción
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 galaxies
is expected to survive since that epoch retaining their compactness and
presenting old stellar populations in the past universe. Using the NYU
Value-Added Galaxy Catalog (DR6), we find only a tiny fraction of
galaxies (˜0.03% ) with re ≤ 1.5 kpc and
M* ≥ 8×1010 Msun in the local
Universe (z˜0.2) Surprisingly, they are relatively young
˜2Gyr) and metal rich ([Z/H˜0.2). These results have been
published in.
