Bayesian recalibration of flux scale factors in diffuse radio maps using low-resolution absolute radiometers

Ainulnabilah Nasirudin, Philip Bull

The Haslam 408 MHz all-sky map is widely used as a template to model the diffuse Galactic synchrotron emission at radio and microwave frequencies. Recent studies have suggested tha…

Joint Bayesian calibration and map-making for intensity mapping experiments

Zheng Zhang, Philip Bull, Mario G. Santos +1

Line-intensity mapping (LIM) is an emerging cosmological technique that traces large-scale structure through the integrated spectral-line emission of unresolved sources. Reconstruc…

RHINO: A large horn antenna for detecting the 21cm global signal

Philip Bull, Ahmed El-Makadema, Hugh Garsden +11

The sky-averaged brightness temperature of the 21cm line from neutral hydrogen provides a sensitive probe of the thermal state of the intergalactic medium, particularly before and…

Characterizing Beam Errors for Radio Interferometric Observations of Reionization

Ainulnabilah Nasirudin, David Prelogovic, Steven G. Murray +2

A limiting systematic effect in 21-cm interferometric experiments is the chromaticity due to the coupling between the sky and the instrument. This coupling is sourced by the instru…

Calibration and 21-cm Power Spectrum Estimation in the Presence of Antenna Beam Variations

Ronniy C. Joseph, C. M. Trott, R. B. Wayth +1

Detecting a signal from the Epoch of Reionisation (EoR) requires an exquisite understanding of galactic and extra-galactic foregrounds, low frequency radio instruments, instrumenta…
