Improving the Epoch of Reionization Power Spectrum Results from Murchison Widefield Array Season 1 Observations
Measurements of 21 cm Epoch of Reionization (EoR) structure are subject to systematics originating from both the analysis and the observation conditions. Using 2013 data from the Murchison Widefield
First Season MWA Phase II Epoch of Reionization Power Spectrum Results at Redshift 7
The compact configuration of Phase II of the Murchison Widefield Array (MWA) consists of both a redundant subarray and pseudo-random baselines, offering unique opportunities to perform sky-model and
Production of bioactive, post-translationally modified, heterotrimeric, human recombinant type-I collagen in transgenic tobacco.
Collagen's biocompatibility, biodegradability and low immunogenicity render it advantageous for extensive application in pharmaceutical or biotechnological disciplines. However, typical collagen
Deep multiredshift limits on Epoch of Reionization 21 cm power spectra from four seasons of Murchison Widefield Array observations
Abstract We compute the spherically averaged power spectrum from four seasons of data obtained for the Epoch of Reionization (EoR) project observed with the Murchison Widefield Array (MWA). We
Absolving the SSINS of Precision Interferometric Radio Data: A New Technique for Mitigating Faint Radio Frequency Interference
TLDR
SSINS is designed to identify and remove faint RFI below the single baseline thermal noise by employing a frequency-matched detection algorithm on baseline-averaged amplitudes of time-differenced visibilities.
Quantifying excess power from radio frequency interference in Epoch of Reionization measurements
We quantify the effect of radio frequency interference (RFI) on measurements of the 21-cm power spectrum during the Epoch of Reionization (EoR). Specifically, we investigate how the frequency
Gridded and direct Epoch of Reionisation bispectrum estimates using the Murchison Widefield Array
Abstract We apply two methods to estimate the 21-cm bispectrum from data taken within the Epoch of Reionisation (EoR) project of the Murchison Widefield Array (MWA). Using data acquired with the
A new MWA limit on the 21 cm power spectrum at redshifts ∼13–17
Observations in the lowest MWA band between 75 − 100MHz have the potential to constrain the distribution of neutral hydrogen in the intergalactic medium at redshift ∼ 13−17. Using 15 hours of MWA
Robust statistics towards detection of the 21 cm signal from the Epoch of Reionization
We explore methods for robust estimation of the 21 cm signal from the Epoch of Reionisation (EoR). A Kernel Density Estimator (KDE) is introduced for measuring the spatial temperature fluctuation
A unified calibration framework for 21 cm cosmology
Calibration precision is currently a limiting systematic in 21 cm cosmology experiments. While there are innumerable calibration approaches, most can be categorized as either `sky-based,' relying on
