A Compact Extreme Scattering Event Cloud Towards AO 0235+164

C. E. Senkbeil, S. P. Ellingsen, J. E. J. Lovell +3

We present observations of a rare, rapid, high amplitude Extreme Scattering Event toward the compact BL-Lac AO 0235+164 at 6.65 GHz. The ESE cloud is compact; we estimate its diame…

First images of 6.7-GHz methanol masers in DR21(OH) and DR21(OH)N

L. Harvey-Smith, R. Soria-Ruiz, A. Duarte-Cabral +1

The first images of 6.7-GHz methanol masers in the massive star-forming regions DR21(OH) and DR21(OH)N are presented. By measuring the shapes, radial velocities and polarization pr…

A deep, high resolution survey of the low frequency radio sky

Emil Lenc, Mike A. Garrett, Olaf Wucknitz +2

We report on the first wide-field, very long baseline interferometry (VLBI) survey at 90 cm. The survey area consists of two overlapping 28 deg^2 fields centred on the quasar J0226…

Observations of Intrahour Variable Quasars: Scattering in our Galactic Neighbourhood

H. E. Bignall, D. L. Jauncey, J. E. J. Lovell +3

Interstellar scintillation (ISS) has been established as the cause of the random variations seen at centimetre wavelengths in many compact radio sources on timescales of a day or l…
