PSF-like Alpha-Particle Events in LSST Images

Guillem Megias Homar, Craig S. Lage, Pierre-François Léget +6

Rare $\hat{I}\pm$-particle-induced charge clusters appear in LSST images as compact, PSF-like sources with a median FWHM of $0.{}^{\prime \prime }95$ and median ellipticity consistent with…
