Prospects for measuring the Doppler magnification dipole with LSST and DESI
Isabelle Ye, Philip Bull, Caroline Guandalin +2
We forecast the detectability of the Doppler magnification dipole with a joint analysis of galaxy spectroscopic redshifts and size measurements. The Doppler magnification arises fr…

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…

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…
