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…

Constraining the intergalactic medium at 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 9.1 using new upper limits on the 21-cm power spectrum measured b…
