![]() "Heavy atoms have been seen in jets from one other system, SS433, but that’s a very unusual system, an oddball, whereas this system is quite typical, much more likely to represent black holes in general," Dr Tzioumis said. When a massive particle is moving it carries more energy than a lighter particle moving at the same speed. The work, led by Dr María Díaz Trigo of the European Southern Observatory, is published in the journal "Nature" today.Īstronomers have known for decades that black-hole jets contain electrons, which are low-mass particles.īut using the European Space Agency's XMM-Newton space telescope and CSIRO's Compact Array radio telescope in northwest NSW, the research team found the first evidence of heavy atoms - iron and nickel - in the jets from a 'typical' black hole known as 4U1630-47.Īn iron atom is about 100,000 times more massive than an electron. "So we want to understand better the impact jets have on their environment." "Jets from supermassive black holes help determine a galaxy's fate - how it evolves," said CSIRO’s Dr Tasso Tzioumis, a member of the research team. ![]() Black-hole jets recycle matter and energy into space and can affect when and where a galaxy forms stars. ![]()
