Story summary

In February 2021, astronomers observed a gamma-ray flare from the blazar TXS 2013+370 with Very Long Baseline Interferometry, performing first multi-frequency polarimetry at 22, 43, and 86 GHz.
The flare is linked to a supermassive black hole and reveals a newly formed jet component, with gamma-ray emissions arising from the blazar's dust torus.
The study's findings were published on November 19, 2025, noting dynamic magnetic-field changes and jet turbulence.
