However, CANDELS alone is not sufficient to fully characterize the galaxy population during this epoch. We are executing the MOSFIRE Deep Evolution Field (MOSDEF) survey over 47 nights with the Keck/MOSFIRE spectrograph. With MOSDEF, we will obtain rest-optical spectra of ~2000 CANDELS galaxies at 1.4<z<3.8. The unique combination of CANDELS and MOSDEF will enable the measurements of the stellar, gaseous, chemical and dust content of galaxies spanning a wider dynamic range in physical properties than has ever been accessed at these redshifts. We propose to conduct the following unique projects: (I) Using accurate sizes and profiles from CANDELS and stellar absorption and emission line kinematics from MOSDEF, we will derive dynamical masses and constrain the physical processes responsible for the structural evolution and growth of quiescent and star-forming galaxies. (II) Using spatially-resolved dust maps and spectral energy distributions from CANDELS in combination with Balmer decrements from MOSDEF, we will obtain the first complete census of the dust geometry and variation in the dust attenuation law in galaxies at z>2. (III) Using rest-frame UV sizes from CANDELS and Halpha star formation rates and outflow signatures from MOSDEF, we will constrain stellar feedback processes and the star formation efficiency in distant galaxies. Finally, we will release all combined CANDELS and MOSDEF data products to the scientific community, which will greatly enhance the legacy value of CANDELS.
