Development and application of an HDF5 schema for SKA-scale image cube visualization
(Elsevier, 2020)In this paper, we describe an HDF5 schema created to support the efficient visualization of the large image cubes that will be produced by SKA Phase 1 and precursor radio telescopes. We demonstrate how the “HDF5-IDIA” ... -
Direction-dependent corrections in polarimetric radio imaging. Iii. A-to-Z solver— Modeling the full jones antenna aperture illumination pattern
(IOP Publishing, 2022)In this third paper of a series describing direction-dependent corrections for polarimetric radio imaging, we present the the A-to-Z solver methodology to model the full Jones antenna aperture illumination pattern (AIP) ... -
Mightee-hi: Evolution of hi scaling relations of star-forming galaxies at z < 0.5*
(IOP Publishing, 2022)We present the first measurements of H I galaxy scaling relations from a blind survey at z > 0.15. We perform spectral stacking of 9023 spectra of star-forming galaxies undetected in H I at 0.23 < z < 0.49, extracted ... -
The tianlai cylinder pathfinder array: System functions and basic performance analysis
(Springer, 2020)The Tianlai Cylinder Pathfinder is a radio interferometer array designed to test techniques for 21 cm intensity mapping in the post-reionization Universe, with the ultimate aim of mapping the large scale structure and ...
