Quantifying the detection likelihood of faint peaks in interferometric data through jackknifing: Test application on finding $z>10$ galaxy candidates

Joshiwa van Marrewijk, Melanie Kaasinen, Gergö Popping +6

False-positive emission-line detections bias our understanding of astronomical sources; for example, falsely identifying $z\sim 3-4$ passive galaxies as $z>10$ galaxies leads to inc…
