Caught in Swallowtails: Discovery of Two Swallowtail Image Formations in MS 0451.6-0305

Ashish K. Meena, Wenlei Chen, Lukas J. Furtak +6

We report the discovery of two swallowtail image formations at and behind the galaxy cluster MS 0451.6-0305 in JWST-NIRCam imaging. We find that in both of the ab…
