UV-continuum slopes beta for z~4-8 galaxies

We measure the UV-continuum slope {beta} for over 4000 high-redshift galaxies over a wide range of redshifts z~4-8 and luminosities from the HST HUDF/XDF, HUDF09-1, HUDF09-2,...我们对红移范围覆盖z≈4至8、光度跨度广泛的4000余颗高红移星系进行了紫外连续谱斜率{β}的测量，这些星系的观测数据源自哈勃太空望远镜（HST, Hubble Space Telescope）的哈勃超深场（HUDF, Hubble Ultra Deep Field）、哈勃极深场（XDF, Hubble eXtreme Deep Field）、HUDF09-1、HUDF09-2等观测项目。
