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…
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…
Fast GPU-Based Seismogram Simulation from Microseismic Events in Marine Environments Using Heterogeneous Velocity Models
Saptarshi Das, Xi Chen, Michael P. Hobson
A novel approach is presented for fast generation of synthetic seismograms due to microseismic events, using heterogeneous marine velocity models. The partial differential equation…
Sampling Errors in Nested Sampling Parameter Estimation
Edward Higson, Will Handley, Mike Hobson +1
Sampling errors in nested sampling parameter estimation differ from those in Bayesian evidence calculation, but have been little studied in the literature. This paper provides the…
