The redshifted 21 cm line is an emerging tool in cosmology, in principle permitting three-
dimensional surveys of our universe that reach unprecedentedly large volumes, previously …

Imaging the Universe during the first hundreds of millions of years remains one of the
exciting challenges facing modern cosmology. Observations of the redshifted 21 cm line of …

LOFAR, the LOw-Frequency ARray, is a new-generation radio interferometer constructed in
the north of the Netherlands and across europe. Utilizing a novel phased-array design …

Abstract The Square Kilometre Array (SKA) will have a low frequency component (SKA-low)
which has as one of its main science goals the study of the redshifted 21 cm line from the …

The H i 21 cm transition line is expected to be an important probe into the cosmic dark ages
and epoch of reionization. Foreground source removal is one of the principal challenges for …

Concerted effort is currently ongoing to open up the Epoch of Reionization (EoR)($ z\sim
$15-6) for studies with IR and radio telescopes. Whereas IR detections have been made of …

The Universe's dark ages end with the formation of the first generation of galaxies. These
objects start emitting ultraviolet radiation that carves out ionized regions around them. After a …

We present the largest-volume (425 Mpc h− 1= 607 Mpc on a side) full radiative transfer
simulation of cosmic reionization to date. We show that there is significant additional power …

Measurement of the spatial distribution of neutral hydrogen via the redshifted 21-cm line
promises to revolutionize our knowledge of the epoch of reionization and the first galaxies …

We introduce a new implementation of the fastica algorithm on simulated Low Frequency
Array Epoch of Reionization data with the aim of accurately removing the foregrounds and …
