| contents | General relativistic instability supernovae at ~10 < z < ~15 are predicted to be observed as red faint point sources, and they can be detected only in the reddest filters in JWST/NIRCam (F444W and F356W). They should be observed as persistent point sources with little flux variations for a couple of decades because of time dilation. We search for static point sources detected only in the F444W filter or only in the F444W and F356W filters in the early JWST deep field data. No real point source of such kind is identified. Therefore, the general relativistic instability supernova rate at ~10 < z < ~15 is constrained to be less than ~ 8e-7 Mpc-3 yr-1 for the first time. |
