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…

Improved upper limits on the 21-cm signal power spectrum of neutral hydrogen at $z \approx 9.1$ 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 $z \approx 9.1$ is presented, based on 141 hours of data obtained with the Low-Frequency Array (LOFAR). The an…

Constraining the intergalactic medium at $z \approx$ 9.1 using LOFAR Epoch of Reionization observations

R. Ghara, S. K. Giri, G. Mellema +19

We derive constraints on the thermal and ionization states of the intergalactic medium (IGM) at redshift $\approx$ 9.1 using new upper limits on the 21-cm power spectrum measured b…
