Title: Fusion systems with some sporadic J-components Authors: Justin Lynd and Julianne Rainbolt Abstract: Aschbacher's program for the classification of simple fusion systems of ``odd'' type at the prime $2$ has two main stages: the classification of $2$-fusion systems of subintrinsic component type and the classification of $2$-fusion systems of $J$-component type. We make a contribution to the latter stage by classifying $2$-fusion systems with a $J$-component isomorphic to the $2$-fusion systems of several sporadic groups under the assumption that the centralizer of such a component is cyclic.
