Massive compact galaxies in the local Universe: what are they?
Recent investigations have provided evidences that many massive (M_* > 10^{11} M_&sun;) spheroid galaxies in the early universe (z ≥ 1.5) were extremely compact (r_e ˜ 1 kpc). According to some galaxy formation theories, a fraction of these massive galaxies in the local Universe would represent surviving relics of the high-z massive galaxies. We
