The LOFAR Two-metre Sky Survey’s second data release catalogued nearly four million radio sources, with detailed visual classifications of about 10,000 large, bright objects. Researchers identified signs of jet precession—possible evidence for binary supermassive black holes—in over a quarter of these sources, revealing new insights into galactic jet dynamics.

Why it matters: Detecting jet precession helps find close binary supermassive black holes, key for understanding galaxy evolution.

The big picture: This study broadens the search for precession signs across various source sizes, luminosities, and host galaxy masses.

Stunning stat: 28% of inspected radio sources exhibit one or more indicators of jet precession.

Quick takeaway: Jet precession features appear in diverse radio galaxies but are more common in massive host galaxies.
