Dust-enshrouded, starbursting, submillimeter galaxies (SMGs) at z ≥ 3 have been proposed as progenitors of z ≥ 2 compact quiescent galaxies (cQGs). To test this connection, we present a detailed spatially resolved study of the stars, dust, and stellar mass in a sample of six submillimeter-bright starburst galaxies at z ~ 4.5. The stellar UV emission probed by HST is extended and irregular and shows evidence of multiple components. Informed by HST, we deblend Spitzer/IRAC data at rest-frame… Expand

Resolving a dusty, star-forming SHiZELS galaxy at z = 2.2 with HST, ALMA, and SINFONI on kiloparsec scales
We present ∼ 0.15′′ spatial resolution imaging of SHiZELS-14, a massive (M∗ ∼ 1011M ), dusty, star-forming galaxy at z = 2.24. Our rest-frame ∼ 1kpc-scale, matched-resolution data comprise fourExpand
Spectral Energy Distributions of Companion Galaxies to z ∼ 6 Quasars
Massive, quiescent galaxies are already observed at redshift z ~ 4, i.e., ~1.5 Gyr after the big bang. Current models predict them to be formed via massive, gas-rich mergers at z > 6. Recent ALMAExpand

Cosmic evolution of submillimeter galaxies and their contribution to stellar mass assembly
