The EoR Sensitivity of the Murchison Widefield Array
A. P. Beardsley, B. J. Hazelton, M. F. Morales +48
Using the final 128 antenna locations of the Murchison Widefield Array (MWA), we calculate its sensitivity to the Epoch of Reionization (EoR) power spectrum of red- shifted 21 cm e…
A new layout optimization technique for interferometric arrays, applied to the MWA
A. P. Beardsley, B. J. Hazelton, M. F. Morales +46
Antenna layout is an important design consideration for radio interferometers because it determines the quality of the snapshot point spread function (PSF, or array beam). This is…
Four Fundamental Foreground Power Spectrum Shapes for 21 cm Cosmology Observations
Miguel F. Morales, Bryna Hazelton, Ian Sullivan +1
Contamination from instrumental effects interacting with bright astrophysical sources is the primary impediment to measuring Epoch of Reionization and BAO 21 cm power spectra---an…
