Non-thermal emission from galaxy clusters: feasibility study with SKA1
Chiara Ferrari, Arwa Dabbech, Oleg Smirnov +20
Galaxy clusters are known to host a variety of extended radio sources: tailed radio galaxies whose shape is modelled by the interaction with the intra-cluster medium (ICM); radio b…
MORESANE: MOdel REconstruction by Synthesis-ANalysis Estimators. A sparse deconvolution algorithm for radio interferometric imaging
Arwa Dabbech, Chiara Ferrari, David Mary +3
(arXiv abridged abstract) The current years are seeing huge developments of radio telescopes and a tremendous increase of their capabilities. Such systems make mandatory the design…
PAINTER: a spatio-spectral image reconstruction algorithm for optical interferometry
Antony Schutz, André Ferrari, David Mary +3
Astronomical optical interferometers sample the Fourier transform of the intensity distribution of a source at the observation wavelength. Because of rapid perturbations caused by…
Statistical characterization of polychromatic absolute and differential squared visibilities obtained from AMBER/VLTI instrument
Antony Schutz, Martin Vannier, David Mary +3
In optical interferometry, the visibility squared modulus are generally assumed to follow a Gaussian distribution and to be independent of each other. A quantitative analysis of th…
Blind and fully constrained unmixing of hyperspectral images
Rita Ammanouil, André Ferrari, Cédric Richard +1
This paper addresses the problem of blind and fully constrained unmixing of hyperspectral images. Unmixing is performed without the use of any dictionary, and assumes that the numb…
