Ultra-fast model emulation with PRISM; analyzing the Meraxes galaxy formation model
Ellert van der Velden, Alan R. Duffy, Darren Croton +1
We demonstrate the potential of an emulator-based approach to analyzing galaxy formation models in the domain where constraining data is limited. We have applied the open-source Py…
Exploring reionisation and high-z galaxy observables with recent multi-redshift MWA upper limits on the 21-cm signal
Bradley Greig, Cathryn M. Trott, Nichole Barry +4
We use the latest multi-redshift () upper limits on the 21-cm signal from the Murchison Widefield Array (MWA) to explore astrophysical models which are inconsistent with…
An efficient hybrid method to produce high resolution large volume dark matter simulations for semi-analytic models of reionisation
Yisheng Qiu, Simon J. Mutch, Pascal J. Elahi +3
Resolving faint galaxies in large volumes is critical for accurate cosmic reionisation simulations. While less demanding than hydrodynamical simulations, semi-analytic reionisation…
Dark-ages reionization and galaxy formation simulation -- XVIII. The high-redshift evolution of black holes and their host galaxies
Madeline A. Marshall, Simon J. Mutch, Yuxiang Qin +2
Correlations between black holes and their host galaxies provide insight into what drives black hole-host co-evolution. We use the Meraxes semi-analytic model to investigate the gr…
Evolution of black hole and galaxy growth in a semi-numerical galaxy formation model
Mackenzie L. Jones, R. C. Hickox, S. J. Mutch +3
We present a simple semi-numerical model designed to explore black hole growth and galaxy evolution. This method builds on a previous model for black hole accretion that uses a sem…
Dark-ages Reionization and Galaxy Formation Simulation -- XIX: Predictions of infrared excess and cosmic star formation rate density from UV observations
Yisheng Qiu, Simon J. Mutch, Elisabete da Cunha +2
We present a new analysis of high-redshift UV observations using a semi-analytic galaxy formation model, and provide self-consistent predictions of the infrared excess (IRX) -- …
