The Impact of Tandem Redundant/Sky-Based Calibration in MWA Phase II Data Analysis

Zheng Zhang, Jonathan C. Pober, Wenyang Li +26

Precise instrumental calibration is of crucial importance to 21-cm cosmology experiments. The Murchison Widefield Array's (MWA) Phase II compact configuration offers us opportuniti…

Detection of Cosmic Structures using the Bispectrum Phase. II. First Results from Application to Cosmic Reionization Using the Hydrogen Epoch of Reionization Array

Nithyanandan Thyagarajan, Chris L. Carilli, Bojan Nikolic +69

Characterizing the epoch of reionization (EoR) at via the redshifted 21 cm line of neutral Hydrogen (HI) is critical to modern astrophysics and cosmology, and thus a k…

Measuring HERA's primary beam in-situ: methodology and first results

Chuneeta D. Nunhokee, Aaron R. Parsons, Nicholas S. Kern +64

The central challenge in 21~cm cosmology is isolating the cosmological signal from bright foregrounds. Many separation techniques rely on the accurate knowledge of the sky and the…

DAYENU: A Simple Filter of Smooth Foregrounds for Intensity Mapping Power Spectra

Aaron Ewall-Wice, Nicholas Kern, Joshua S. Dillon +14

We introduce DAYENU, a linear, spectral filter for HI intensity mapping that achieves the desirable foreground mitigation and error minimization properties of inverse co-variance w…

Redundant-Baseline Calibration of the Hydrogen Epoch of Reionization Array

Joshua S. Dillon, Max Lee, Zaki S. Ali +76

In 21 cm cosmology, precision calibration is key to the separation of the neutral hydrogen signal from very bright but spectrally-smooth astrophysical foregrounds. The Hydrogen Epo…
