Evidence for profile changes in PSR J1713+0747 using the uGMRT
Jaikhomba Singha, Mayuresh P Surnis, Bhal Chandra Joshi +29
PSR J1713+0747 is one of the most precisely timed pulsars in the international pulsar timing array experiment. This pulsar showed an abrupt profile shape change between April 16, 2…
High Precision Measurements of Interstellar Dispersion Measure with the upgraded GMRT
M. A. Krishnakumar, P. K. Manoharan, Bhal Chandra Joshi +19
Pulsar radio emission undergoes dispersion due to the presence of free electrons in the interstellar medium (ISM). The dispersive delay in the arrival time of pulsar signal changes…
Observed glitches in 8 young pulsars
Avishek Basu, Bhal Chandra Joshi, M. A. Krishnakumar +5
The abrupt change in the pulse period of a pulsar is called a pulsar glitch. In this paper, we present eleven pulsar glitches detected using the Ooty Radio Telescope (ORT) and the…
Multi-frequency scatter broadening evolution of pulsars - II. Scatter broadening of nearby pulsars
M. A. Krishnakumar, Yogesh Maan, Bhal Chandra Joshi +1
We present multi-frequency scatter broadening evolution of 29 pulsars observed with the LOw Frequency ARray (LOFAR) and Long Wavelength Array (LWA). We conducted new observations u…
Follow-up Timing of Three GMRT Pulsars
Mayuresh P. Surnis, Bhal Chandra Joshi, Maura A. McLaughlin +3
We report on the results of multi-frequency follow-up observations of three pulsars (PSRs J0026+6320, J2208+5500 and J2217+5733) discovered with the Giant Metrewave Radio Telescope…
A Search for Pulsars in Steep Spectrum Radio Sources
Yogesh Maan, Cees Bassa, Joeri van Leeuwen +2
We report on a time-domain search for pulsars in 44 steep spectrum radio sources originally identified from recent imaging surveys. The time-domain search was conducted at 327 MHz…
