Source Finding in Linear Polarization for LOFAR, and SKA Predecessor Surveys, using Faraday Moments
J. S. Farnes, G. Heald, H. Junklewitz +10
The optimal source-finding strategy for linear polarization data is an unsolved problem, with many inhibitive factors imposed by the technically-challenging nature of polarization…
Wide-field LOFAR-LBA power-spectra analyses: Impact of calibration, polarization leakage and ionosphere
B. K. Gehlot, L. V. E. Koopmans, A. G. de Bruyn +9
Contamination due to foregrounds (Galactic and Extra-galactic), calibration errors and ionospheric effects pose major challenges in detection of the cosmic 21 cm signal in various…
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 (…
