Profile changes associated with DM events in PSR J1713+0747

Abstract: Propagation effects in the interstellar medium and intrinsic profile changes can cause variability in the timing of pulsars, which limits the accuracy of fundamental science done via pulsar timing. One of the best timing pulsars, PSR J1713+0747, has gone through two "dip" events in its dispersion measure time series. If these events reflect real changes in electron column density, they should lead to multiple imaging. We show that the events are are well-fit by an underdense corrugated sheet model, and look fo… Show more

“…No evidence was reported for a change in the average profile of this pulsar during these two events. In the previous events, a 1% change in the amplitude relative to the mean profile was reported in the timing residuals (Lin et al 2021).…”

“…However, this pulsar has shown two timing events in the past, where a jump in the timing residuals was observed followed by an exponential recovery with a timescale of about 62 and 25 days for the events in 2008 and 2016, respectively (Lam et al 2018;Goncharov et al 2020). Both these events were interpreted as chromatic events, suggesting a connection with the line-ofsight passing through inter-stellar medium (ISM) structures (Lin et al 2021). No evidence was reported for a change in the average profile of this pulsar during these two events.…”
