Semi-analytic modelling of Pop. III star formation and metallicity evolution -- II. Impact on 21cm power spectrum
Emanuele M. Ventura, Yuxiang Qin, Sreedhar Balu +1
Simulating Population (Pop.) III star formation in mini-halos in a large cosmological simulation is an extremely challenging task but it is crucial to estimate its impact on the 21…
The Impact of ionization Morphology and X-ray Heating on the Cosmological 21cm Skew Spectrum
J. H. Cook, S. Balu, B. Greig +4
The cosmological 21cm signal offers a potential probe of the early Universe and the first ionizing sources. Current experiments probe the spatially-dependent variance (Gaussianity)…
Fisher matrix forecasts on the astrophysics of galaxies during the epoch of reionisation from the 21-cm power spectra
Sreedhar Balu, Bradley Greig, J. Stuart B. Wyithe
The hyperfine 21-cm transition of neutral hydrogen from the early Universe () is a sensitive probe of the formation and evolution of the first luminous sources. Using the Fish…
Thermal and Reionisation History within a Large-Volume Semi-Analytic Galaxy Formation Simulation
Sreedhar Balu, Bradley Greig, Yisheng Qiu +4
We predict the 21-cm global signal and power spectra during the Epoch of Reionisation using the MERAXES semi-analytic galaxy formation and reionisation model, updated to include X-…
