Evidence
Evidence for The Bullet Cluster & Collision Evidence
Chandra X-ray observations locate the hot gas, while Hubble and ground-based lensing measurements locate the dominant mass peaks separately. Similar systems provide additional collision tests, though detailed modeling is important.
Chapter review
Assessment still in review.
The chapter is published, but its assessment has not completed the verification and QA pipeline yet. It will appear here after publication.

The Bullet Cluster is a collision between two galaxy clusters in which most ordinary baryonic mass, observed as X-ray-emitting gas, is spatially separated from most of the gravitationally inferred mass mapped by lensing.
