First Results from HERA Phase I: Upper Limits on the Epoch of Reionization 21 cm Power Spectrum
Abdurashidova, Zara; Aguirre, James E.; Alexander, Paul; Ali, Zaki S.; Balfour, Yanga; e.a. (American Astronomical Society, 2022-02-01)We report upper limits on the Epoch of Reionization 21 cm power spectrum at redshifts 7.9 and 10.4 with 18 nights of data (∼36 hr of integration) from Phase I of the Hydrogen Epoch of Reionization Array (HERA). The Phase ... -
H i 21 cm Cosmology and the Bi-spectrum: Closure Diagnostics in Massively Redundant Interferometric Arrays
Carilli, C.L.; Nikolic, Bojan; Thyagarajan, Nithyanandan; Gale-Sides, K.; Abdirashidova, Zara; e.a. (2018)New massively redundant low frequency arrays allow for a novel investigation of closure relations in interferometry. We employ commissioning data from the Hydrogen Epoch of Reionization Array to investigate closure ... -
