A 21-cm power spectrum at 48 MHz, using the Owens Valley Long Wavelength Array
Hugh Garsden, Lincoln Greenhill, Gianni Bernardi +6
The Large-aperture Experiment to detect the Dark Age (LEDA) was designed to measure the 21-cm signal from neutral hydrogen at Cosmic Dawn, 15-30. Using observations mad…
maxsmooth: Rapid Maximally Smooth Function Fitting With Applications in Global 21-cm Cosmology
H. T. J. Bevins, W. J. Handley, A. Fialkov +3
Maximally Smooth Functions (MSFs) are a form of constrained functions in which there are no inflection points or zero crossings in high order derivatives. Consequently, they have a…
Bayesian constraints on the global 21-cm signal from the Cosmic Dawn
G. Bernardi, J. T. L. Zwart, D. Price +7
The birth of the first luminous sources and the ensuing epoch of reionization are best studied via the redshifted 21-cm emission line, the signature of the first two imprinting the…
A study of fundamental limitations to statistical detection of redshifted HI from the epoch of reionization
Nithyanandan Thyagarajan, N. Udaya Shankar, Ravi Subrahmanyan +46
In this paper we explore for the first time the relative magnitudes of three fundamental sources of uncertainty, namely, foreground contamination, thermal noise and sample variance…
Low Frequency Observations of the Moon with the Murchison Widefield Array
B. McKinley, F. Briggs, D. L. Kaplan +49
A new generation of low frequency radio telescopes is seeking to observe the redshifted 21 cm signal from the Epoch of Reionization (EoR), requiring innovative methods of calibrati…
HI Epoch of Reionization Arrays
L. J. Greenhill, G. Bernardi
There are few data available with which to constrain the thermal history of the intergalactic medium (IGM) following global recombination. Thus far, most constraints flow from anal…
Subtraction of point sources from interferometric radio images through an algebraic forward modeling scheme
G. Bernardi, D. A. Mitchell, S. M. Ord +4
We present a method for subtracting point sources from interferometric radio images via forward modeling of the instrument response and involving an algebraic nonlinear minimizatio…
