Two articles – one published in the journal “Nature Astronomy” and one in “The Astrophysical Journal Letters” – report different aspects of a study of the blazar cataloged as VLASS J041009.05−013919.88, or simply J0410−0139, the most distant found so far. Two teams of researchers used several space and ground-based telescopes and some radio telescopes to obtain detections in various electromagnetic bands.
