We present coincident observations of the Cosmic Microwave Background (CMB) from the Very Small Array (VSA) and Cosmic Background Imager (CBI) telescopes. The consistency of the fu…
Mapping of the SZ effect in the cluster Cl 0016+16 with the Ryle Telescope
K. Grainge, W. F. Grainger, M. E. Jones +3
We have mapped the high-redshift (z = 0.546) cluster Cl 0016+16 with the Ryle Telescope at 15 GHz. The Sunyaev-Zel'dovich decrement is clearly detected, and resolved. We combine ou…
A close-pair binary in a distant triple supermassive black-hole system
R. P. Deane, Z. Paragi, M. J. Jarvis +8
Galaxies are believed to evolve through merging, which should lead to multiple supermassive black holes in some. There are four known triple black hole systems, with the closest pa…
