A faint blue source is recovered at the SN position with brightness $m_{F435W}=26.76\\pm0.20$, $m_{F555W}=26.60\\pm0.23$ and $m_{F625W} = 26.32\\pm0.19$ mags, although there is no detection in a contemporaneous narrow-band $\\mathrm{H\\alpha}$ image. The spectral energy distribution of the late-time source is well fit by a stellar-like spectrum ($\\log T_{eff} > 3.7$ and $\\log L / L_{\\odot} > 4$) subject to only a small degree of reddening consiste"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1609.07739","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
