21CMMC: an MCMC analysis tool enabling astrophysical parameter studies of the cosmic 21 cm signal (2015, background): “…(5) where X2Y is a cosmological conversion factor between observing bandwidth, frequency and comoving distance units, Ω′ is a beam-dependent factor derived in Parsons et al. (2014), t is the total time spent by all baselines within a particular k mode and Tsys is the system temperature, the sum of…”
What does the first highly redshifted 21-cm detection tell us about early galaxies? (2018, background): “…model – which is representative of the kinds of models used broadly in the high-z galaxy evolution community (e.g. Dayal et al. 1This result is consistent with previous limits from PAPER (Parsons et al. 2014; Pober et al. 2015), which required only that the IGM have been heated prior to z ∼ 9.”

FIRST SEASON MWA EOR POWER SPECTRUM RESULTS AT REDSHIFT 7 (2016, methodology): “Using the first generation of instruments, several upper limits have been placed on the 21 cm EoR signal (Ali et al. 2015; Dillon et al. 2014; Parsons et al. 2014; Jacobs et al. 2015; Paciga et al. 2013).”
PAPER-64 CONSTRAINTS ON REIONIZATION: THE 21 cm POWER SPECTRUM AT z = 8.4 (2015, methodology): “That the excesses at k ≈ 0.30 and 0.44h Mpc−1 are relatively unaffected by the filtering could be an indication that they are more isotropically distributed, but more likely, it may mean that the simply arise closer to the center of the primary beam where they are downweighted less.”
