A more probable explanation for a continuum flash in the direction of a redshift $\approx$ 11 galaxy

TL;DR

This paper suggests that a continuum flash observed near a high-redshift galaxy is more likely caused by Solar system objects rather than a gamma-ray burst, challenging previous interpretations of the event.

Contribution

It introduces the hypothesis that Solar system objects are a more probable cause for the observed transient than a gamma-ray burst in the early Universe.

Findings

Multiple similar transient signals found in archival data.

Solar system objects are a more plausible explanation for the phenomena.

The conclusion remains robust despite additional points raised.

Abstract

Recent work reported the discovery of a gamma-ray burst (GRB) associated with the galaxy GN-z11 at $z\sim 11$. The extreme improbability of the transient source being a GRB in the very early Universe requires robust elimination of all plausible alternative hypotheses. We identify numerous examples of similar transient signals in separate archival MOSFIRE observations and argue that Solar system objects -- natural or artificial -- are a far more probable explanation for these phenomena. An appendix has been added in response to additional points raised in Jiang et al. (2021), which do not change the conclusion.
