Extended Data Fig. 6: A comparison of models for luminous blue transients.
From: A nearby long gamma-ray burst from a merger of compact objects
a, b, The UVOIR counterpart (squares) is compared with a set of models producing luminous (Lbol ≈ 1042 erg s−1) and short-lived (<7 d) transients: a low-nickel SN from a fallback collapsar25 underpredicts the optical/near infrared emission (a); a magnetar-powered kilonova31 does not easily reproduce the timescales and colours (b). Upper limits (downward triangles) are 3σ.
