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…
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…
Sunyaev--Zel'dovich profile fitting with joint AMI-Planck analysis
Yvette C. Perrott, Kamran Javid, Pedro Carvalho +5
We develop a Bayesian method of analysing Sunyaev-Zel'dovich measurements of galaxy clusters obtained from the Arcminute Microkelvin Imager (AMI) radio interferometer system and fr…
Physical modelling of galaxy clusters using Einasto dark matter profiles
Kamran Javid, Yvette C. Perrott, Clare Rumsey +1
We derive a model for Sunyaev--Zel'dovich data from a galaxy cluster which uses an Einasto profile to model the cluster's dark matter component. This model is similar to the physic…
Physical modelling of galaxy clusters detected by Planck
Kamran Javid, Malak Olamaie, Yvette C. Perrott +5
We present a comparison of mass estimates for galaxy cluster candidates from the second Planck catalogue (PSZ2) of Sunyaev-Zel'dovich sources. We compare the mass values obtai…
Comparison of physical and observational galaxy cluster modelling
Kamran Javid, Yvette C. Perrott, Michael P. Hobson +3
We present a comparison between three cluster models applied to data obtained by the Arcminute Microkelvin Imager radio interferometer system. The physical model (PM) parameterises…
