A 15.5 GHz detection of the galaxy cluster minihalo in RXJ1720.1+2638

Yvette C. Perrott, Pedro Carvalho, Patrick J. Elwood +6

RXJ1720.1+2638 is a cool-core, 'relaxed-appearing' cluster with a minihalo previously detected up to 8.4 GHz, confined by X-ray-detected cold fronts. We present observations of the…

GLOBALEMU: A novel and robust approach for emulating the sky-averaged 21-cm signal from the cosmic dawn and epoch of reionisation

H. T. J. Bevins, W. J. Handley, A. Fialkov +2

Emulation of the Global (sky-averaged) 21-cm signal with neural networks has been shown to be an essential tool for physical signal modelling. In this paper we present globalemu, a…

Compromise-free Bayesian neural networks

Kamran Javid, Will Handley, Mike Hobson +1

We conduct a thorough analysis of the relationship between the out-of-sample performance and the Bayesian evidence (marginal likelihood) of Bayesian neural networks (BNNs), as well…

Geometric nested sampling: sampling from distributions defined on non-trivial geometries

Kamran Javid

Metropolis Hastings nested sampling evolves a Markov chain, accepting new points along the chain according to a version of the Metropolis Hastings acceptance ratio, which has been…

Physical modelling of galaxy clusters and Bayesian inference in astrophysics

Kamran Javid

I compare the mass values obtained with data taken from the Arcminute Microkelvin Imager (AMI) radio interferometer system and from the Planck satellite. The former of these uses a…

Nested sampling on non-trivial geometries

Kamran Javid

Metropolis nested sampling evolves a Markov chain from a current livepoint and accepts new points along the chain according to a version of the Metropolis acceptance ratio modified…
