Using the latest upper limits on the 21-cm power spectrum at $z\approx9.1$ from the Low Frequency Array (LOFAR), we explore regions of parameter space which are inconsistent with the data. We use 21CMMC, a Monte Carlo Markov Chain sampler of 21cmFAST

This paper presents the results from one of the first observations of ionospheric scintillation taken using the Low-Frequency Array (LOFAR). The observation was of the strong natural radio source Cas A, taken overnight on 18-19 August 2013, and exhib

Systematic biases in low frequency radio interferometric data due to calibration: the LOFAR EoR case

Patil, Ajinkya H., Yatawatta, Sarod, Zaroubi, Saleem, Koopmans, Léon V. E., de Bruyn, A. G., Jelić, Vibor, Ciardi, Benedetta, Iliev, Ilian T., Mevius, Maaijke, Pandey, Vishambhar N., Gehlot, Bharat K.
The redshifted 21 cm line of neutral hydrogen is a promising probe of the Epoch of Reionization (EoR). However, its detection requires a thorough understanding and control of the systematic errors. We study two systematic biases observed in the LOFAR

Future high redshift 21-cm experiments will suffer from a high degree of contamination, due both to astrophysical foregrounds and to non-astrophysical and instrumental effects. In order to reliably extract the cosmological signal from the observed da
