DOIAbstract
Our goal is to estimate the star formation main sequence (SFMS) and the star formation rate density (SFRD) at z 8 and it is clearly defined by the blue galaxies, with the red galaxies located below them. The SFMS is described as log SFR = 0.83 log M - 8.44. We find a good agreement with previous estimations of the SFMS, especially those based on integral field spectroscopy. The Halpha luminosity function of the AGN-free sample is well described by a Schechter function with log L* = 41.34, log phi* = -2.43, and alpha = -1.25. Our measurements provide a lower characteristic luminosity than several previous studies in the literature. The derived star formation rate density at d <75 Mpc is log rho_SFR = -2.10 +- 0.11, with red galaxies accounti...
