AMI-LA Observations of the SuperCLASS Super-cluster
C. J. Riseley, K. J. B. Grainge, Y. C. Perrott +21
We present a deep survey of the SuperCLASS super-cluster - a region of sky known to contain five Abell clusters at redshift - performed using the Arcminute Microkelvin I…
AMI-CL J0300+2613: a Galactic anomalous-microwave-emission ring masquerading as a galaxy cluster
Yvette C. Perrott, Therese M. Cantwell, Steve H. Carey +17
The Arcminute Microkelvin Imager (AMI) carried out a blind survey for galaxy clusters via their Sunyaev-Zel'dovich effect decrements between 2008 and 2011. The first detection, kno…
A Digital Correlator Upgrade for the Arcminute MicroKelvin Imager
Jack Hickish, Nima Razavi-Ghods, Yvette C. Perrott +18
The Arcminute Microkelvin Imager (AMI) telescopes located at the Mullard Radio Astronomy Observatory near Cambridge have been significantly enhanced by the implementation of a new…
Stabilized Modulated Photonic Signal Transfer Over 186 km of Aerial Fiber
David Gozzard, Sascha Schediwy, Bruce Wallace +2
Aerial suspended optical-fiber links are being considered as economical alternatives to buried links for long-distance transfer of coherent time and frequency signals. We present s…
AMI SZ observation of galaxy-cluster merger CIZA J2242+5301: perpendicular flows of gas and dark matter
Clare Rumsey, Yvette C. Perrott, Malak Olamaie +5
AMI observations towards CIZA J2242+5301, in comparison with observations of weak gravitational lensing and X-ray emission from the literature, are used to investigate the behaviou…
Free-form modelling of galaxy clusters: a Bayesian and data-driven approach
Malak Olamaie, Michael P. Hobson, Farhan Feroz +5
A new method is presented for modelling the physical properties of galaxy clusters. Our technique moves away from the traditional approach of assuming specific parameterised functi…
