Deep learning-based deconvolution for interferometric radio transient reconstruction
Benjamin Naoto Chiche, Julien N. Girard, Joana Frontera-Pons +2
Radio astronomy is currently thriving with new large ground-based radio telescopes coming online in preparation for the upcoming Square Kilometre Array (SKA). Facilities like LOFAR…
Galaxy Image Restoration with Shape Constraint
Fadi Nammour, Morgan A. Schmitz, Fred Maurice Ngolè Mboula +2
Images acquired with a telescope are blurred and corrupted by noise. The blurring is usually modeled by a convolution with the Point Spread Function and the noise by Additive Gauss…
Pulsars with NenuFAR: backend and pipelines
L. Bondonneau, J. -M. Grießmeier, G. Theureau +27
NenuFAR (New extension in Nançay upgrading LoFAR) is a new radio telescope developed and built on the site of the Nançay Radio Observatory. It is designed to observe the largely un…
Primary beam effects of radio astronomy antennas -- II. Modelling the MeerKAT L-band beam
K. M. B. Asad, J. N. Girard, M. de Villers +12
After a decade of design and construction, South Africa's SKA-MID precursor MeerKAT has begun its science operations. To make full use of the widefield capability of the array, it…
Kliko - The Scientific Compute Container Format
Gijs Molenaar, Spheshile Makhathini, Julien N. Girard +1
Kliko is a Docker-based container specification for running one or multiple related compute jobs. The key concepts of Kliko are the encapsulation of data processing software into a…
NOIRE Study Report: Towards a Low Frequency Radio Interferometer in Space
Baptiste Cecconi, Moustapha Dekkali, Carine Briand +13
Ground based low frequency radio interferometers have been developed in the last decade and are providing the scientific community with high quality observations. Conversely, curre…
Sparse representations and convex optimization as tools for LOFAR radio interferometric imaging
Julien N. Girard, Hugh Garsden, Jean Luc Starck +5
Compressed sensing theory is slowly making its way to solve more and more astronomical inverse problems. We address here the application of sparse representations, convex optimizat…
LOFAR Sparse Image Reconstruction
H. Garsden, J. N. Girard, J. L. Starck +77
Context. The LOw Frequency ARray (LOFAR) radio telescope is a giant digital phased array interferometer with multiple antennas distributed in Europe. It provides discrete sets of F…
