Redshift-space distortions in simulations of the 21-cm signal from the cosmic dawn
Hannah E. Ross, Sambit K. Giri, Keri L. Dixon +3
The 21-cm signal from the Cosmic Dawn (CD) is likely to contain large fluctuations, with the most extreme astrophysical models on the verge of being ruled out by observations from…
The 21cm bispectrum as a probe of non-Gaussianities due to X-ray heating
Catherine A. Watkinson, Sambit K. Giri, Hannah E. Ross +4
We present analysis of the normalised 21-cm bispectrum from fully-numerical simulations of intergalactic-medium heating by stellar sources and high-mass X-ray binaries (HMXB) durin…
New simulation of QSO X-ray heating during the Cosmic Dawn
Hannah Ross, Keri Dixon, Garrelt Mellema +1
The upcoming radio interferometer Square Kilometre Array is expected to directly detect the redshifted 21-cm signal from the Cosmic Dawn for the first time. In this era temperature…
Simulating the Impact of X-ray Heating during the Cosmic Dawn
Hannah E. Ross, Keri L. Dixon, Ilian T. Iliev +1
Upcoming observations of the 21-cm signal from the Epoch of Reionization will soon provide the first direct detection of this era. This signal is influenced by many astrophysical e…
