However, the scientific consensus has shifted significantly since publication. Ren, Garrett & Siemion (2025, MNRAS Letters 538, L56) used high-resolution e-MERLIN + EVN radio imaging to confirm Candidate G is a false positive — its IR excess is caused by a background radio-loud AGN (VLASS J233532.86-000424.9, brightness temperature >10^8 K). Furthermore, theoretical analysis shows that Hot Dust-Obscured Galaxies (Hot DOGs) with an areal sky density of ~9×10^-6 per sq arcsec can probably account for contamination of ALL 7 candidates within the ~6 arcsec WISE PSF. Candidates A and B also have radio associations, further supporting the background contamination hypothesis. JWST MIRI spectroscopy remains the definitive test — it can spatially resolve contaminants and spectroscopically distinguish silicate dust grains from a featureless artificial blackbody. As of early 2025, no confirmed Dyson sphere has been found, but the search methodology remains valuable for advancing SETI observational techniques."
