| Abstract: |
We have reported the detection of Off-pulse emission in Basu et al. (2011)
in two long period pulsars B0525+21 and B2045–16 at 325 MHz using the Giant
Metrewave Radio Telescope. We have extended our studies to detect Off-pulse
emission in two more pulsars B1237+25 and B0834+06 at 325 MHz. We also
report the detection of Off-pulse emission in B0525+21 and B2045–16 at
610 MHz. The long periodicity and low spin down energies of the pulsars
studied make it highly unlikely for the detected emission to be due to
Pulsar Wind Nebulae. The location of the Off-pulse emission far away from
the On-pulse on the other hand gives rise to interesting questions about
the structure of the pulsar magnetosphere and the emission mechanism if
the Off-pulse emission is magnetospheric in origin. |
