Absolute Calibration Strategies for the Hydrogen Epoch of Reionization Array and Their Impact on the 21 cm Power Spectrum
Kern, NS; Dillon, JS; Parsons, AR; Carilli, CL; Bernardi, G; Abdurashidova, Z; Aguirre, JE; Alexander, P; Ali, ZS; Balfour, Y (American Astronomical Society, 2020-02-20)We discuss absolute calibration strategies for Phase I of the Hydrogen Epoch of Reionization Array (HERA), which aims to measure the cosmological 21 cm signal from the Epoch of Reionization. HERA is a drift-scan array with ... -

Mitigating Internal Instrument Coupling for 21 cm Cosmology. II. A Method Demonstration with the Hydrogen Epoch of Reionization Array
Kern, NS; Parsons, AR; Dillon, JS; Lanman, AE; Liu, A; Bull, P; Ewall-Wice, A; Abdurashidova, Z; Aguirre, JE; Alexander, P (The American Astronomical Society, 2020-01-10)We present a study of internal reflection and cross-coupling systematics in Phase I of the Hydrogen Epoch of Reionization Array (HERA). In a companion paper, we outlined the mathematical formalism for such systematics and ... -
