Catching Up on State Transitions in Cygnus X-1 (2008)
Boeck, Moritz, Hanke, Manfred, Wilms, Joern, Grinberg, Victoria, Pottschmidt, Katja, Markoff, Sera, ...
In 2005 February we observed Cygnus X-1 over a period of 10 days quasi-continuously with the Rossi X-ray Timing Explorer and the Ryle telescope. We present the results of the spectral and timing...
An INTEGRAL monitoring of GRS 1915+105 using simultaneous space and ground based instruments (2006)
Rodriguez, Jerome, Pooley, Guy, Hannikainen, Diana, Lehto, Harry J., Belloni, Tomaso, Cadolle-Bel, Marion, ...
We report the results of 3 observations of GRS 1915+105 during which the source is found to show the X-ray dips/spike sequences (cycles). These observations were performed simultaneously with...
Is the `IR Coincidence' Just That? (2005)
Nowak, Michael, Wilms, Joern, Heinz, Sebastian, Pooley, Guy, Pottschmidt, Katja, Corbel, Stephane
(Abridged) Motch (1985) suggested that in the hard state of GX 339-4 the soft X-ray power-law extrapolated backward in energy agrees with the IR flux. Corbel & Fender (2002) showed that the hard...

Very Small Array observations of the Sunyaev-Zel'dovich effect in nearby galaxy clusters (2004)
Lancaster, Katy, Genova-Santos, Ricardo, Falcon, Nelson, Grainge, Keith, Gutierrez, Carlos, Kneissl, Ruediger, ...
We present VSA observations (~34GHz) on scales ~20 arcmin towards a complete, X-ray-flux-limited sample of seven clusters at redshift z
High sensitivity measurements of the CMB power spectrum with the extended Very Small Array (2004)
Dickinson, Clive, Battye, Richard A., Cleary, Kieran, Davies, Rod D., Davis, Richard J., Genova-Santos, Ricardo, ...
We present deep Ka-band ($\nu \approx 33$ GHz) observations of the CMB made with the extended Very Small Array (VSA). This configuration produces a naturally weighted synthesized FWHM beamwidth of...
A universal radio/X-ray correlation in low/hard state black hole binaries (2003)
Gallo, Elena, Fender, Rob, Pooley, Guy
We present a comprehensive study of (quasi-)simultaneous radio:X-ray observations of stellar black hole binaries during the spectrally hard X-ray state, finding evidence for a strong correlation...
First results from the Very Small Array -- III. The CMB power spectrum (2002)
Scott, Paul F., Carreira, Pedro, Cleary, Kieran, Davies, Rod D., Davis, Richard, Dickinson, Clive, ...
We present the power spectrum of the fluctuations in the cosmic microwave background detected by the Very Small Array (VSA) in its first season of observations in its compact configuration. We find...
Discovery of circularly polarised radio emission from SS 433 (1999)
Fender, Robert, Rayner, David, Norris, Ray, Sault, R. J., Pooley, Guy
We report the discovery of circularly polarised radio emission from the radio-jet X-ray binary SS 433 with the Australia Telescope Compact Array. The flux density spectrum of the circular...
Baker, Joanne C., Grainge, Keith, Hobson, M. P., Jones, Michael E., Kneissl, R., Lasenby, A. N., ...
We describe observations at frequencies near 15 GHz of the second 2x2 degree field imaged with the Cambridge Cosmic Anisotropy Telescope (CAT). After the removal of discrete radio sources, structure...
Determining the Hubble Constant from Ryle Telescope observations (1999)
Grainge, Keith, Jones, Michael E., Pooley, Guy, Saunders, Richard, Edge, Alastair, Kneissl, Rudiger
We describe our algorithm for measuring the Hubble constant from Ryle Telescope (RT) interferometric observations of the Sunyaev-Zel'dovich (SZ) effect from a galaxy cluster and observation of the...
Detection of a CMB decrement towards the (1999)
Pc+ A B, Michael E. Jones, Richard Saunders, Joanne C. Baker, Garret Cotter, Alastair Edge, ...
In a 15-GHz Ryle-Telescope observation of PC1643+4631 A & B, a pair of quasars at redshifts z = 3:79 and 3.83 separated by 198 00 on the sky, we find a decrement in the cosmic microwave background...
Detection of a CMB decrement towards the (1997)
Pc+ A B, Michael E. Jones, Richard Saunders, Joanne C. Baker, Garret Cotter, Alastair Edge, ...
In a 15-GHz Ryle-Telescope observation of PC1643+4631 A & B, a pair of quasars at redshifts z = 3:79 and 3.83 separated by 198 00 on the sky, we find a decrement in the cosmic microwave background...
