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…

Detecting the neutral IGM in filaments with the SKA

Robin Kooistra, Marta B. Silva, Saleem Zaroubi +3

The intergalactic medium (IGM) plays an important role in the formation and evolution of galaxies. Recent developments in upcoming radio telescopes are starting to open up the poss…

The first power spectrum limit on the 21-cm signal of neutral hydrogen during the Cosmic Dawn at z=20-25 from LOFAR

B. K. Gehlot, F. G. Mertens, L. V. E. Koopmans +19

Observations of the redshifted 21-cm hyperfine line of neutral hydrogen from early phases of the Universe such as Cosmic Dawn and the Epoch of Reionization promise to open a new wi…
