Upper limits on the 21-cm Epoch of Reionization power spectrum from one night with LOFAR
A. H. Patil, S. Yatawatta, L. V. E. Koopmans +25
We present the first limits on the Epoch of Reionization (EoR) 21-cm HI power spectra, in the redshift range , using the Low-Frequency Array (LOFAR) High-Band Antenna (…
Probing Ionospheric Structures using the LOFAR radio telescope
M. Mevius, S. van der Tol, V. N. Pandey +24
LOFAR is the LOw Frequency Radio interferometer ARray located at mid-latitude (). Here, we present results on ionospheric structures derived from 29 LOFAR nighttim…
Systematic biases in low frequency radio interferometric data due to calibration: the LOFAR EoR case
Ajinkya H. Patil, Sarod Yatawatta, Saleem Zaroubi +8
The redshifted 21 cm line of neutral hydrogen is a promising probe of the Epoch of Reionization (EoR). However, its detection requires a thorough understanding and control of the s…
Linear polarization structures in LOFAR observations of the interstellar medium in the 3C196 field
V. Jelić, A. G. de Bruyn, V. N. Pandey +21
This study aims to characterize linear polarization structures in LOFAR observations of the interstellar medium (ISM) in the 3C196 field, one of the primary fields of the LOFAR-Epo…
Polarization leakage in Epoch of Reionization windows: I. LOFAR observations of the 3C196 field
K. M. B. Asad, L. V. E. Koopmans, V. Jelić +25
Detection of the 21-cm signal coming from the epoch of reionization (EoR) is challenging especially because, even after removing the foregrounds, the residual Stokes maps conta…
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…
Constraining the epoch of reionization with the variance statistic: simulations of the LOFAR case
Ajinkya H. Patil, Saleem Zaroubi, Emma Chapman +27
Several experiments are underway to detect the cosmic redshifted 21-cm signal from neutral hydrogen from the Epoch of Reionization (EoR). Due to their very low signal-to-noise rati…
