X-ray binary Swift J1727.8-1613 has a large relativistic jet, observations show

Using the Very Long Baseline Array (VLBA) and the Long Baseline Array (LBA), astronomers have observed a black hole low-mass X-ray binary known as Swift J1727.8-1613. As a result, they found that the system hosts a highly extended and bright relativistic jet. The finding was detailed in a paper published May 20 on the pre-print server arXiv.
