Size of the Vela Pulsar's Emission Region at 18 cm Wavelength
C. R. Gwinn, M. D. Johnson, J. E. Reynolds +12
We present measurements of the linear diameter of the emission region of the Vela pulsar at observing wavelength lambda=18 cm. We infer the diameter as a function of pulse phase fr…

Constraining the Vela Pulsar's Radio Emission Region Using Nyquist-Limited Scintillation Statistics
Michael D. Johnson, Carl R. Gwinn, Paul Demorest
Using a novel technique, we achieve ~100 picoarcsecond resolution and set an upper bound of less than 4 km for the characteristic size of the Vela pulsar's emission region. Specifi…
