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…
Cosmological performance of SKA HI galaxy surveys
S. Yahya, P. Bull, M. G. Santos +4
The Square Kilometre Array (SKA) will conduct the biggest spectroscopic galaxy survey ever, by detecting the 21cm emission line of neutral hydrogen (HI) from around a billion galax…
Fast Large Volume Simulations of the 21 cm Signal from the Reionization and pre-Reionization Epochs
M. G. Santos, L. Ferramacho, M. B. Silva +2
While limited to low spatial resolution, the next generation low-frequency radio interferometers that target 21 cm observations during the era of reionization and prior will have i…
