Cosmic SFRD in the OBELISK volume for all galaxies (in light blue), only for galaxies forming stars faster than 0.3 M_⊙ yr⁻¹ (dashed dark purple line), and for all galaxies within 1 Mpc of the most massive galaxy (dash-dotted light purple line). The simulation should be compared to the protocluster observations of Kato et al. (2016, green diamond), Kubo et al. (2019, black error bar), Cheng et al. (2019, red triangles) and Harikane et al. (2019, teal error bar). The model of Madau & Dickinson (2014, dotted black line) and the observations of Oesch et al. (2018, green squares) are only here to guide the eye.
