The Impact of HI in Galaxies on 21-cm Intensity Fluctuations During the Reionisation Epoch
Stuart Wyithe, Lila Warszawski, Paul M. Geil +1
We investigate the impact of neutral hydrogen (HI) in galaxies on the statistics of 21-cm fluctuations using analytic and semi-numerical modelling. Following the reionisation of hy…
Modification of the 21-cm power spectrum by X-rays during the epoch of reionisation
Lila Warszawski, Paul M. Geil, Stuart Wyithe
We incorporate a contribution to reionization from X-rays within analytic and semi-numerical simulations of the 21-cm signal arising from neutral hydrogen during the epoch of reion…
The effect of Galactic foreground subtraction on redshifted 21-cm observations of quasar HII regions
Paul. M. Geil, Stuart Wyithe, Nada Petrovic +1
We assess the impact of Galactic synchrotron foreground removal on the observation of high-redshift quasar HII regions in redshifted 21-cm emission. We consider the case where a qu…
Measurement of the baryonic acoustic oscillation scale in 21 cm intensity fluctuations during the reionisation era
Kirsty J. Rhook, Paul M. Geil, J. Stuart B. Wyithe
It has recently been suggested that the power spectrum of redshifted 21cm fluctuations could be used to measure the scale of baryonic acoustic oscillations (BAOs) during the reioni…
Baryonic Acoustic Oscillations in 21cm Emission: A Probe of Dark Energy out to High Redshifts
Stuart Wyithe, Abraham Loeb, Paul Geil
Low-frequency observatories are currently being constructed with the goal of detecting redshifted 21cm emission from the epoch of reionization. These observatories will also be abl…
The Impact of a Percolating IGM on Redshifted 21 cm Observations of Quasar HII Regions
Paul M. Geil, Stuart Wyithe
We assess the impact of inhomogeneous reionization on detection of HII regions surrounding luminous high redshift quasars using planned low frequency radio telescopes. Our approach…
