The Pearson-Readhead survey of compact extragalactic radio sources from space I. The images (2001)

Lister, Matthew L., Tingay, Steven J., Murphy, David W., Piner, B. Glenn, Jones, Dayton L., Preston, Robert A.

We present images from a space-VLBI survey using the facilities of the VLBI Space Observatory Programme (VSOP), drawing our sample from the well-studied Pearson-Readhead survey of extragalactic radio...

The Pearson-Readhead survey of compact extragalactic radio sources from space II. Analysis of Source Properties (2001)

Lister, Mathew L., Tingay, Steven J., Preston, Robert A.

We have performed a multidimensional correlation analysis on the observed properties of a statistically complete core-selected sample of compact radio-loud active galactic nuclei based on data from...

The subparsec-scale structure and evolution of Centaurus A II : continued very long baseline array monitoring (2001)

Tingay, Steven J., Preston, Robert A., Jauncey, David L.

We present the results of continued 8.4 GHz Very Long Baseline Array monitoring of the subparsec-scale structure and evolution of Centaurus A, following on from the initial results presented in 1998...

The 1997 hard state outburst of the X-ray transient GS 1354-64/BW Cir (2001)

Brocksopp, Catherine, Fender, Robert P., Groot, Paul J., Jonker, Peter G., Tingay, Steven J., Van Der Klis, Michael

We present observations of the 1997 outburst of the X-ray transient GS 1354−64 (BW Cir) at X-ray, optical and, for the first time, radio wavelengths; our results include upper limits to the linear...
