Self-consistent spatially-resolved star formation histories of 2 < z < 3 galaxies from CANDELS
Description
In order to shed new light on how Milky Way-like galaxies are formed, we analyze the star formation histories (SFHs) and mass surface density proles of massive galaxies (log(M/M) > 10) at 2 < z < 3 in the GOODS-N and GOODS-S fields observed by the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS). Stellar population parameters are obtained in two-dimensions (2D) by first performing multiwavelength photometry using optical and near-infrared broad-band data from HST. Subsequently, the observed SEDs are t to stellar population models attenuated by dust. The galaxy sample has been divided according to its activity (star-forming vs: quiescent) and compactness (compact vs: extended). We will discuss the differences in SFH and mass distribution for each subsample and propose an evolutionary connection among them.
