Cartoon diagram of the CSM orientations favored by our multiwavelength constraints on EP 260321a/SN 2026gzf. Our analysis favors two distinct regions of CSM that produce the X-ray (inner region) and SN light curve (outer region). Further, we favor an outer CSM structure that is clumpy, aspherical, porous, and/or characterized by a steep density drop outside the region probed through the SN light curve.
