Dry minor mergers and size evolution of high-z compact massive early-type galaxies

Recent observations show evidence that high-z (z ∼ 2-3) early-type galaxies (ETGs) are more compact than those with comparable mass at z ∼ 0. Such size evolution is most likely explained by the 'dry merger sceanario'. However, previous studies based on this scenario cannot consistently exp...
