Bayesian estimation of cross-coupling and reflection systematics in 21cm array visibility data

Geoff G. Murphy, Philip Bull, Mario G. Santos +76

Observations with radio arrays that target the 21-cm signal originating from the early Universe suffer from a variety of systematic effects. An important class of these are reflect…

1-arcsecond imaging of ELAIS-N1 field at 144MHz using the LoTSS survey with international LOFAR telescope

Haoyang Ye, Frits Sweijen, Reinout van Weeren +10

We present the first wide area (2.5 x 2.5 deg^2) LOFAR High Band Antenna image at a resolution of 1.2'' x 2'' with a median noise of approximately 80 microJy per beam. It was made…

Trajectory Based RFI Subtraction and Calibration for Radio Interferometry

Chris Finlay, Bruce A. Bassett, Martin Kunz +1

Radio interferometry calibration and Radio Frequency Interference (RFI) removal are usually done separately. Here we show that jointly modelling the antenna gains and RFI has signi…
