Hubble diagrams for SLSN Ic. Different cosmologies are plotted in comparison with that chosen (solid black line) to measure the distance moduli of the sample presented. Left panels: the distance moduli measured using the ΔM₃₀ decline relation. Right panels: the distance moduli measured using the peak magnitude–color decline relation. The lower panels show the residuals of the distances relative to a Ω_M = 0.27, Ω_Λ = 0 universe. The brown dashed vertical line represents the SN Ia upper limit with the current generation of telescopes (ground and space), whereas the gold dashed line represents an approximate limit for discovery and monitoring of SLSN Ic with the current generation of telescopes.
