Morphological Parameters of Galaxies at z ~ 8 in the BoRG and CANDELS Survey
Abstract
We analyze the Gini value G and asymmetry value A of a sample of 10 high-redshift galaxies. These galaxies were confirmed high-redshift and discovered in the BoRG and CANDELS surveys. From this, we can confirm that the sample is from the same population and is not contaminated. The morphological values lay in the ranges 0.18 < G < 0.3 and 0.3 < A < 0.8 with errors included. These morphological parameters also do not appear to correlate with each other nor with photometric redshift, IRAC color [3.6]-[4.5], and half-light radius. Being one of the first analyses of high-redshift morphology, this may lay the foundation for what to look for within these galaxies and implications and practices to be used in the future. This includes use in redshift candidacy and galaxy and stellar formations in this epoch.
