21cmfish: Fisher-matrix framework for fast parameter forecasts from the cosmic 21-cm signal
Charlotte A. Mason, Julian B. Muñoz, Bradley Greig +2
The 21-cm signal from neutral hydrogen in the early universe will provide unprecedented information about the first stars and galaxies. Extracting this information, however, requir…
Calibrating excursion set reionization models to approximately conserve ionizing photons
Jaehong Park, Bradley Greig, Andrei Mesinger
The excursion set reionization framework is widely used, due to its speed and accuracy in reproducing the 3D topology of reionization. However, it is known that it does not conserv…
21cmFAST v3: A Python-integrated C code forgenerating 3D realizations of the cosmic 21cm signal
Steven G. Murray, Bradley Greig, Andrei Mesinger +4
This brief code paper presents a new Python-wrapped version of the popular 21cm cosmology simulator, 21cmFAST. The new version, v3+, maintains the same core functionality of previo…
A tale of two sites -- II: Inferring the properties of minihalo-hosted galaxies with upcoming 21-cm interferometers
Yuxiang Qin, Andrei Mesinger, Bradley Greig +1
The first generation of galaxies is expected to form in minihalos, accreting gas through cooling, and possessing unique properties. Although unlikely to be directly det…
Reionization inference from the CMB optical depth and E-mode polarization power spectra
Yuxiang Qin, Vivian Poulin, Andrei Mesinger +3
The Epoch of Reionization (EoR) depends on the complex astrophysics governing the birth and evolution of the first galaxies and structures in the intergalactic medium. EoR models r…
A tale of two sites -- I: Inferring the properties of minihalo-hosted galaxies from current observations
Yuxiang Qin, Andrei Mesinger, Jaehong Park +2
The very first galaxies that started the cosmic dawn likely resided in so-called "minihaloes", with masses of -, accreting their gas from the interg…
