A practical preconditioner for wide-field continuum imaging of radio interferometric data

ratt-ru/pfb-imaging 20 Jan 2021

The celebrated CLEAN algorithm has been the cornerstone of deconvolution algorithms in radio interferometry almost since its conception in the 1970s.

Reconstructing Video from Interferometric Measurements of Time-Varying Sources

achael/eht-imaging 3 Nov 2017

Most recently, the Event Horizon Telescope (EHT) has extended VLBI to short millimeter wavelengths with a goal of achieving angular resolution sufficient for imaging the event horizons of nearby supermassive black holes.

DeepSource: Point Source Detection using Deep Learning

vafaei-ar/deepsource 7 Jul 2018

For uniformly-weighted images it achieves a Purity x Completeness (PC) score at SNR = 3 of 0. 73, compared to 0. 31 for the best PyBDSF model.

Learned radio interferometric imaging for varying visibility coverage

astro-informatics/leia 14 May 2024

The challenge in designing learned, data-driven reconstruction techniques for radio interferometry is that they need to be agnostic to the varying visibility coverages of the telescope, since these are different for each observation.

Self-supervised learning for radio-astronomy source classification: a benchmark

dr4thmos/solo-learn-radio 21 Nov 2024

This study explores the application of SSL to radio astronomy, comparing the performance of SSL-trained models with that of traditional models pretrained on natural images, evaluating the importance of data curation for SSL, and assessing the potential benefits of self-supervision to different domain-specific radio astronomy datasets.

Energy and polarization based on-line interference mitigation in radio interferometry

sarodyatawatta/flagpol 19 Dec 2024

We combine statistics based on the energy as well as the polarization alignment of the correlated signal to develop an on-line RFI mitigation scheme that can be applied to a data stream produced by the correlator in real-time, especially targeted at low duty-cycle or transient RFI detection.

IRIS: A Bayesian Approach for Image Reconstruction in Radio Interferometry with expressive Score-Based priors

enceladecandy/iris 5 Jan 2025

Inferring sky surface brightness distributions from noisy interferometric data in a principled statistical framework has been a key challenge in radio astronomy.
