We investigate the degree of dust obscured star formation in 49 massive ({\rm log}_{10}(M_{\star}/{\rm M}_{\odot})>9) Lyman-break galaxies (LBGs) at z = 6.5-8 observed as part of the ALMA Reionization Era Bright Emission Line Survey (REBELS) large program. By creating deep stacks of the photometric data and the REBELS ALMA measurements... Show more
