We find that the parameters of the explosion are fully consistent with those expected from the shock breakout associated with a Type II supernova of a progenitor star of $\\sim 300$ solar masses in this galaxy, with of order unity such events expected over an observing timescale of a few years. We forecast the expected number of such transients from $z > 10$ galaxies as a function of their host stellar mass and star formation rate.", "revisions": [ { "version": "v1", "updated": "2021-01-28T19:00:03.000Z" } ], "analyses": { "keywords": [ "cosmic dawn", "gn-z11-flash", "population", "shock-breakout", "host stellar mass" ], "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable" } } }
