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…
Comparing Foreground Removal Techniques for Recovery of the LOFAR-EoR 21cm Power Spectrum
Ian Hothi, Emma Chapman, Jonathan R. Pritchard +10
We compare various foreground removal techniques that are being utilised to remove bright foregrounds in various experiments aiming to detect the redshifted 21cm signal of neutral…
Interpreting LOFAR 21-cm signal upper limits at z~9.1 in the context of high-z galaxy and reionisation observations
Bradley Greig, Andrei Mesinger, Léon V. E. Koopmans +11
Using the latest upper limits on the 21-cm power spectrum at from the Low Frequency Array (LOFAR), we explore regions of parameter space which are inconsistent with t…
Lyman-alpha transmission properties of the intergalactic medium in the CoDaII simulation
Max Gronke, Pierre Ocvirk, Charlotte Mason +10
The decline in abundance of Lyman- (Ly) emitting galaxies at is a powerful and commonly used probe to constrain the progress of cosmic reionization. We use the…
Tight Constraints on the Excess Radio Background at from LOFAR
R. Mondal, A. Fialkov, C. Fling +13
The ARCADE2 and LWA1 experiments have claimed an excess over the Cosmic Microwave Background (CMB) at low radio frequencies. If the cosmological high-redshift contribution to this…
Improved upper limits on the 21-cm signal power spectrum of neutral hydrogen at from LOFAR
F. G. Mertens, M. Mevius, L. V. E Koopmans +23
A new upper limit on the 21-cm signal power spectrum at a redshift of is presented, based on 141 hours of data obtained with the Low-Frequency Array (LOFAR). The an…
