The Progenitors of the Compact Early-Type Galaxies at High-Redshift
Christina C. Williams, Mauro Giavalisco, Paolo Cassata +19
We use GOODS and CANDELS images to identify progenitors of massive (log M > 10 Msun) compact "early-type" galaxies (ETGs) at z~1.6. Since merging and accretion increase the size of…
