Functional Analysis of Widefield Radio Interferometry
Nichole Barry, Jaiden Cook, Cathryn Trott +2
Radio interferometry relies on reconstruction techniques to form images from discrete visibility measurements. As instruments encompass wider fields of view, the nuance of that rec…
The Murchison Widefield Array Phase III upgrade: Sensitivity Doubled, Number of Baselines Quadrupled, Flexibility Enhanced, and EoR Observations Optimised
S. J. Tingay, M. Johnston-Hollitt, R. B. Wayth +32
We describe the latest iteration of upgrades (designated Phase III) to the Murchison Widefield Array (MWA), in the fourth paper in a series that covers the evolution of the telesco…
Strategy for mitigation of systematics for EoR experiments with the Murchison Widefield Array
Chuneeta D. Nunhokee, Dev Null, Cathryn M. Trott +4
Observations of the 21 cm signal face significant challenges due to bright astrophysical foregrounds that are several orders of magnitude higher than the brightness of the hydrogen…
The challenges of low-frequency radio polarimetry: lessons from the Murchison Widefield Array
Emil Lenc, C. S. Anderson, N. Barry +26
We present techniques developed to calibrate and correct Murchison Widefield Array (MWA) low frequency (72-300 MHz) radio observations for polarimetry. The extremely wide field-of-…
Empirical Covariance Modeling for 21 cm Power Spectrum Estimation: A Method Demonstration and New Limits from Early Murchison Widefield Array 128-Tile Data
Joshua S. Dillon, Abraham R. Neben, Jacqueline N. Hewitt +52
The separation of the faint cosmological background signal from bright astrophysical foregrounds remains one of the most daunting challenges of mapping the high-redshift intergalac…
A Laboratory-based Hard X-ray Monochromator for High-Resolution X-ray Emission Spectroscopy and X-ray Absorption Near Edge Structure Measurements
G. T. Seidler, D. R. Mortensen, A. J. Remesnik +5
We report the development of a laboratory-based Rowland-circle monochromator that incorporates a low poer x-ray (bremsstrahlung) tube source, a spherically-bent crystal analyzer (S…
Modeling Pulse Characteristics in Xenon with NEST
Jeremy Mock, Nichole Barry, Kareem Kazkaz +5
A comprehensive model for describing the characteristics of pulsed signals, generated by particle interactions in xenon detectors, is presented. An emphasis is laid on two-phase ti…
