Proposal Type: Regular
General Category: Pulsars
Observation Category: Galactic
Total Time Requested: 34.5 Hours
Proposal Title: Understanding the Emission Geometry of Radio Pulsars
ABSTRACT:
In order to better understand the emission geometry of radio pulsars { specically the location and distribution of
the emission regions in the magnetosphere { we propose to observe 10 carefully selected pulsars at frequencies of
430 MHz and 1175 MHz, using the PSPM and WAPP pulsar back-ends , respectively. The single pulse data
obtained will be analyzed using a new method developed by us to detect faint and overlapping emission
components in the proles and thereby to get the detailed emission geometry for these pulsars. The results from
this study would be important for understanding pulsar emission mechanisms. The proposal calls for a total of
34.5 hours of telescope time.

Instrument Setup
430 G 610 L-wide 430 CH receiver L-narrow
Atmospheric Optical Instruments:
Special Equipment or setup: Several Mammoth 1 and 2 tapes.
RFI Considerations
Frequency Ranges Planned
425-435 (or 50 MHz if available)
1100-1300
(we may possibly use 710 MHz receiver
in place of L-band for some brighter
targets)
This proposal requires coordination with Punta Salinas radar within the band 1222-1381 MHz..
This proposal requires coordination with GPS L3 at 1381 MHz.
This proposal requires coordination with AFTWF within the band 425-435 MHz.
