Interstellar Holography
Mark Walker, Leon Koopmans, Dan Stinebring +1
The dynamic spectrum of a radio pulsar is an in-line digital hologram of the ionised interstellar medium. It has previously been demonstrated that such holograms permit image recon…
SINS -- Observational Review
Carl Heiles, Dan Stinebring
We present a highly personal and biased review of the observational portion of this meeting. We cover Tiny-Scale Atomic, Molecular, and Ionized Structure (TSAS, TSMS, TSIS), emphas…
LOFAR: A powerful tool for pulsar studies
B. W. Stappers, A. G. J. van Leeuwen, M. Kramer +2
The LOw Frequency ARray, LOFAR, will have the sensitivity, bandwidth, frequency range and processing power to revolutionise low-frequency pulsar studies. We present results of simu…
Deflection of Pulsar Signal Reveals Compact Structures in the Galaxy
Alex S. Hill, Daniel R. Stinebring, Curtis T. Asplund +3
We have detected a strong deflection of radio waves from the pulsar PSR B0834+06 in scintillation observations. Interference between the undeflected pulsar image and deflected subi…
Theory of Parabolic Arcs in Interstellar Scintillation Spectra
James M. Cordes, Barney J. Rickett, Daniel R. Stinebring +1
Our theory relates the secondary spectrum, the 2D power spectrum of the radio dynamic spectrum, to the scattered pulsar image in a thin scattering screen geometry. Recently discove…
Interpretation of parabolic arcs in pulsar secondary spectra
Mark Walker, Don Melrose, Dan Stinebring +1
Pulsar dynamic spectra sometimes show organised interference patterns; these patterns have been shown to have power spectra which often take the form of parabolic arcs, or sequence…
