Abstract: We report the discovery of Cerberus, an extremely red object detected with the MIRI Deep Imaging Survey (MIDIS) observations in the F1000W filter of the Hubble Ultra Deep Field. The object is detected at S/N~6, with F1000W~27 mag, and it is extremely faint in both the NIRCam data gathered by the JWST Advanced Deep Extragalactic Survey, JADES, with ~30.5 mag $5sigma$ upper limits in individual bands, as well as in the MIDIS F560W ultra deep data ($sim$29 mag, $5sigma$). Analyzing the spectral energy distribution built with individual (low S/N) optical-to-mid-infrared filters and (S/N~5) stacks, we discuss the possible nature of this red NIRCam-dark source using a battery of codes. We discard the possibility of Cerberus being a Solar System body based on the $arXiv:2402.16942v1 Announce Type: new
