Radiojets sind nichts Ungewöhnliches im All - mit diesem Alter allerdings schon.

By revealing a massive radio jet in the early universe, J1601+3102 offers a rare snapshot of early quasar activity.

Astronomers have observed a supermassive black hole at the center of galaxy J1007+3540 suddenly reactivating after nearly 100 million years of dormancy. Using advanced radio telescopes, including LOFAR in the Netherlands and India's upgraded GMRT, researchers captured detailed images of powerful jets emanating from the black hole. These jets interact with the dense environment of the surrounding galaxy cluster, creating distorted structures spanning almost a million light-years. The observations reveal multiple cycles of black hole activity, with fresh jets nested inside older, fading plasma. The extreme pressure from the cluster compresses and bends these jets, highlighting how the environment shapes the galaxy's structure. A faint tail of emission shows magnetized plasma being dragged across the cluster, demonstrating long-term interaction with surrounding gas. Studies like this help scientists understand the episodic nature of black holes, how jets evolve, and how galaxies are influenced by both internal activity and external forces. Ongoing research aims to track the movement of these new jets and better understand the life cycles of supermassive black holes and their impact on galaxy evolution.

A triple-galaxy merger is when three galaxies are colliding and will eventually combine into one larger galaxy. It happens through gravity, as tidal forces and dynamical friction drain orbital energy, funnel gas inward, and pull the galaxies and their central supermassive black holes together over hundreds of millions of years. In rare cases, all three black holes are active at once, producing radio jets that reveal a triple active galactic nucleus.
