  • We present 20 years of timing observations for 1E 1207.4−5209, the central compact object in supernova remnant PKS 1209−51/52, to follow up on our detection of an unexpected timing glitch in its spin-down. Using new XMM-Newton and NICER observations of 1E 1207.4−5209, we now find that the phase ephemeris can be well-modelled by either two small glitches, or extreme timing noise. The implied magnitudes of the frequency glitches are ∆f/f = (9±2)×10 and ∆f/f = (3.7±0.7)×10, at epochs 2010.9 and… CONTINUE READING
