Exploring the Ionized ISM by observing two bright nearby pulsars: B0950+08

and B1133+16
ABSTRACT:
Pulsar scintillation observations are a powerful probe of the ionized interstellar medium. Arecibo observations are state-of-the-art because several key observations are sensitivity-limited. Scintillation arcs, discovered at Arecibo immediately following the upgrade (Stinebring et al. 2001) yield great detail about the intervening scattering medium, but they require excellent S/N to be observable in detail. Building on previous published observations we request 20-epoch, weekly observations of two nearby and extremely bright pulsars in a not-heavily-subscribed part of the sky: B0950+08 and B1133+16. We propose to make 45-min observations of each pulsar at both 327-MHz and 430-MHz to study the scintillation arc development with frequency. When possible, we will make LOFAR single-station observations (frequency 110-190 MHz) simultaneous with the Arecibo observations.
