Lunar occultation of the diffuse radio sky: LOFAR measurements between 35 and 80 MHz

H. K. Vedantham, L. V. E. Koopmans, A. G. de Bruyn +91

We present radio observations of the Moon between and MHz to demonstrate a novel technique of interferometrically measuring large-scale diffuse emission extending far bey…

Initial LOFAR observations of Epoch of Reionization windows: II. Diffuse polarized emission in the ELAIS-N1 field

V. Jelic, A. G. de Bruyn, M. Mevius +106

This study aims to characterise the polarized foreground emission in the ELAIS-N1 field and to address its possible implications for the extraction of the cosmological 21-cm signal…

Probing reionization with LOFAR using 21-cm redshift space distortions

Hannes Jensen, Kanan K. Datta, Garrelt Mellema +24

One of the most promising ways to study the epoch of reionization (EoR) is through radio observations of the redshifted 21-cm line emission from neutral hydrogen. These observation…

LEDDB: LOFAR Epoch of Reionization Diagnostic Database

O. Martinez-Rubi, V. K. Veligatla, A. G. de Bruyn +6

One of the key science projects of the Low-Frequency Array (LOFAR) is the detection of the cosmological signal coming from the Epoch of Reionization (EoR). Here we present the LOFA…

Initial deep LOFAR observations of Epoch of Reionization windows: I. The North Celestial Pole

S. Yatawatta, A. G. de Bruyn, M. A. Brentjens +86

The aim of the LOFAR Epoch of Reionization (EoR) project is to detect the spectral fluctuations of the redshifted HI 21cm signal. This signal is weaker by several orders of magnitu…

Prospects for detecting the 21cm forest from the diffuse intergalactic medium with LOFAR

B. Ciardi, P. Labropoulos, A. Maselli +20

We discuss the feasibility of the detection of the 21cm forest in the diffuse IGM with the radio telescope LOFAR. The optical depth to the 21cm line has been derived using simulati…

LOFAR insights into the epoch of reionization from the cross power spectrum of 21cm emission and galaxies

R. P. C. Wiersma, B. Ciardi, R. M. Thomas +18

Using a combination of N-body simulations, semi-analytic models and radiative transfer calculations, we have estimated the theoretical cross power spectrum between galaxies and the…

Imaging neutral hydrogen on large-scales during the Epoch of Reionization with LOFAR

S. Zaroubi, A. G. de Bruyn, G. Harker +17

The first generation of redshifted 21 cm detection experiments, carried out with arrays like LOFAR, MWA and GMRT, will have a very low signal-to-noise ratio per resolution element…
