In this paper we show that every graph G of bounded maximum average degree mad(G) and with maximum degree Δ can be edge-colored using the optimal number of Δ colors in quasilinear time, whenever Δ ≥ 2mad(G). The maximum average degree is within a multiplicative constant of other popular graph sparsity parameters like arboricity, degeneracy or maximum density. Our algorithm extends previous results of Chrobak and Nishizeki [Marek Chrobak and Takao Nishizeki, 1990] and Bhattacharya, Costa, Panski and Solomon [Sayan Bhattacharya et al., 2023].
