A wobbling magnetised star challenges the origin of repeating fast radio bursts
The rapid decay of a magnetar’s precession after an X-ray outburst likely rules out free precession as their origin

An international research team led by Gregory Desvignes from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has used the Effelsberg and Jodrell Bank radio telescopes to observe the precessing magnetar XTE J1810-197 — a highly magnetised and ultra-dense neutron star — shortly after its X-ray enhanced activity and radio reactivation. This precession damped on a timescale of a few months challenging some models used to explain the origin of the mysterious repeating fast radio bursts. more
Lightest black hole or heaviest neutron star?
MeerKAT uncovers a mysterious object at the boundary between black holes and neutron stars

An international team of astronomers, led by researchers from the Max Planck Institute for Radio Astronomy, have used the MeerKAT radio telescope to discover an intriguing object of an unknown nature in the globular cluster NGC 1851. The massive object is heavier than the heaviest neutron stars known and yet simultaneously lighter than the lightest black holes known and is in orbit around a rapidly spinning millisecond pulsar. This could be the first discovery of the much-coveted radio pulsar - black hole binary; a stellar pairing that would allow new tests of Einstein’s general relativity. more
