Proposal Title: Contrasting core and conal dominated single pulses of radio pulsars.
ABSTRACT:
The superb sensitivity of the Arecibo telescope at 430 MHz makes it a unique instrument for studies that demand
high sensitivity such as single pulse polarimetry of normal pulsars. The upgraded telescope, equiped with the
state-of-the-art instrumentation such as the Princeton Mark IV baseband recorder, opens up new horizons for high
resolution pulsar studies which are crucial when deciphering the physics of pulsar emission. In particular,
understanding the polarization properties of radio emission and hence interpreting them correctly is of great
signi cance into other elds of pulsar research. Polarization is frequently used to derive the beam shape and the
viewing geometry of pulsars, parameters that have to be incorporated in any model aiming at synthesizing the
galactic pulsar population. Consequenty, studies like the one proposed here are essential in interpreting polarization
data. We intend to study the single-pulse polarization properties of core and conal pulsars and then compare them
with the mean properties, which are known to di er markedly in those two types of pro les. We request a total of
12 h with the 430 MHz receiver to obtain high-quality single pulse polarimetry.
