Observing it with the upgraded GMRT over a period of about a year, we see that the profile shows some signature of mode changes between its various components. K-S test and Monte-Carlo simulations support our initial results. J2124-3358 is already a well-timed pulsar at the uGMRT. Hence, discovering mode changes in this pulsar and accounting for them is likely to improve the precision of its times-of-arrival significantly. |
