First Season MWA Phase II EoR Power Spectrum Results at Redshift 7
W. Li, J. C. Pober, N. Barry +44
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 per…
Probing Small Scale Primordial Power Spectrum with 21cm Line Global Signal
Shintaro Yoshiura, Keitaro Takahashi, Tomo Takahashi
We argue that the global signal of neutral hydrogen 21cm line can be a powerful probe of primordial power spectrum on small scales. Since the amplitude of small scale primordial fl…
Science with the Murchison Widefield Array: Phase I Results and Phase II Opportunities
A. P. Beardsley, M. Johnston-Hollitt, C. M. Trott +56
The Murchison Widefield Array (MWA) is an open access telescope dedicated to studying the low frequency (80300 MHz) southern sky. Since beginning operations in mid 2013, the MWA…
Gridded and direct Epoch of Reionisation bispectrum estimates using the Murchison Widefield Array
Cathryn M. Trott, Catherine A. Watkinson, Christopher H. Jordan +42
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 wit…
Robust statistics toward detection of the 21 cm signal from the Epoch of Reionisation
Cathryn M. Trott, Shih Ching Fu, Steven Murray +26
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 temperat…
Detectability of CMB Weak Lensing and HI Cross Correlation and constraints on cosmological parameters
Shoichiro Tanaka, Shintaro Yoshiura, Kenji Kubota +3
Neutral hydrogen (H) intensity mapping is capable of measuring redshift evolution of H density parameter , which is an important parameter to…
