The crescent shape looks like it could be side view of the ionized part of a shock wave (maybe there’s a better word for it).

The paper isn’t clear about this, but the crescent in that image is the moon, AFAIU. They’re using it as a baseline for luminosity of the UAPs, which are the multiple (less bright) white speckles in the image.
