The particles release radio waves, and so are detectable using radio telescopes. The research team involved found signs of a pulsar, a neutron star spinning at high speed, in the same region as the broken bone. The suspected collision is thought to have distorted the magnetic field of the bone, causing its radio signal to deform. It is possibly the aforementioned neutron star. Pulsars are alternative versions of a neutron star where, in addition to being compact objects, they rotate at high velocities and produce strong magnetic fields.
