UV-continuum β slopes of individual z \sim 2-6 clumps and their evolution

We study the ultraviolet (UV) continuum \beta slope of a sample of 166 clumps, individual star-forming regions observed in high redshift galaxies. They are hosted by 67 galaxies with redshift between 2 and 6.2, strongly lensed by the Hubble Frontier Fields cluster of galaxies MACS J0416.1-2403. The \beta slope is... Show more
