Wide-band Timing of GMRT-discovered Millisecond Pulsars

Modeling of frequency-dependent effects, contributed by the turbulence in free electron density interstellar plasma, is required to enable detection expected imprints from stochastic gravitational-wave (GW) background pulsar timing data. In this work, we present an investigation temporal variations medium for a set millisecond pulsars (MSPs) with upgraded GMRT aided large fractional bandwidth at lower observing frequencies. Contrary conventional narrow-band analysis using frequency invariant template profile, applied $PulsePortraiture$ based wide-band while correcting evolution profile frequency. Implementation method discovered MSPs probe DM resulted precision $10^{-4}\,pc~cm^{-3}$. general, achieve similar and compared matching DMs. This study newly over wide range highlights effectiveness profile-modeling low frequencies probes potential them array.
