Extremely Anisotropic Scintillations (2008)
Walker, Mark, De Bruyn, Ger, Bignall, Hayley
A small number of quasars exhibit interstellar scintillation on time-scales less than an hour; their scintillation patterns are all known to be anisotropic. Here we consider a totally anisotropic...
The nature of gamma ray blazar candidate PMN J1326-5256 (2008)
Bignall, Hayley, Cimo, Giuseppe, Jauncey, David, Senkbeil, Cliff, Lovell, Jim, Ellingsen, Simon
A comparison of AGN detected at gamma ray energies by EGRET with flat-spectrum radio sources observed in surveys for intraday variability reveals that a remarkably high fraction of EGRET blazars show...
Interstellar scintillation, AGN physics and the SKA (2008)
Bignall, Hayley, Lovell, J, Rickett, B.J., Macquart, Jean-Pierre, Jauncey, J., Kedziora-Chudczer, L., ...
A large fraction of compact, extragalactic radio sources exhibit rapid variability at centimetre wavelengths as their radio emission is scattered by electron density fluctuations in the interstellar...
