IGM damping wing constraints on reionisation from covariance reconstruction of two QSOs
Bradley Greig, Andrei Mesinger, Frederick B. Davies +3
Bright, high redshift () QSOs are powerful probes of the ionisation state of the intervening intergalactic medium (IGM). The detection of Ly damping wing absorption imprint…
Calibrating excursion set reionization models to approximately conserve ionizing photons
Jaehong Park, Bradley Greig, Andrei Mesinger
The excursion set reionization framework is widely used, due to its speed and accuracy in reproducing the 3D topology of reionization. However, it is known that it does not conserv…
Epoch of Reionization Power Spectrum Limits from Murchison Widefield Array Data Targeted at EoR1 Field
M. Rahimi, B. Pindor, J. L. B. Line +28
Current attempts to measure the 21cm Power Spectrum of neutral hydrogen during the Epoch of Reionization are limited by systematics which produce measured upper limits above both t…
The Impact of the First Galaxies on Cosmic Dawn and Reionization
Julian B. Muñoz, Yuxiang Qin, Andrei Mesinger +3
The formation of the first galaxies during cosmic dawn and reionization (at redshifts ), triggered the last major phase transition of our universe, as hydrogen evolved from…
SKA-Low Intensity Mapping Pathfinder Updates: Deeper 21 cm Power Spectrum Limits from Improved Analysis Frameworks
Nichole Barry, Gianni Bernardi, Bradley Greig +2
The Square Kilometre Array (SKA) is a planned radio interferometer of unprecedented scale that will revolutionize low-frequency radio astronomy when completed. In particular, one o…
Automated Detection of Antenna Malfunctions in Large-N Interferometers: A Case Study with the Hydrogen Epoch of Reionization Array
Dara Storer, Joshua S. Dillon, Daniel C. Jacobs +75
We present a framework for identifying and flagging malfunctioning antennas in large radio interferometers. We outline two distinct categories of metrics designed to detect outlier…
