On bursty star formation during cosmological reionization -- influence on the metal and dust content of low-mass galaxies
Anand Menon, Sreedhar Balu, Chris Power
Observations indicate that high-redshift galaxies undergo episodic star formation bursts, driving strong outflows that expel gas and suppress accretion. We investigate the conseque…
The DORCHA suite: nature, nurture, and the phase space distribution of the Milky Way's high redshift progenitors today
Sreedhar Balu, Chris Power, Kris Walker +1
Where in the present-day Milky Way should we search for the remnants of its earliest stars? We address this question using the DORCHA (Gaelic for Dark; DUR-uh-khuh) suite: a set of…
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…
On the Use of WGANs for Super-Resolution in Dark-Matter Simulations
John Brennan, Sreedhar Balu, Yuxiang Qin +2
Super-resolution techniques have the potential to reduce the computational cost of cosmological and astrophysical simulations. This can be achieved by enabling traditional simulati…
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)…
Semi-analytic modelling of Pop. III star formation and metallicity evolution -- I. Impact on the UV luminosity functions at z = 9-16
Emanuele M. Ventura, Yuxiang Qin, Sreedhar Balu +1
We implemented Population III (Pop. III) star formation in mini-halos within the MERAXES semi-analytic galaxy formation and reionisation model, run on top of a N-body simulation wi…
Implications of JWST galaxies for galaxy formation at high redshift
Yuxiang Qin, Sreedhar Balu, J. Stuart B. Wyithe
Using a semi-analytic galaxy-formation model, we study analogues of 8 recently discovered JWST galaxies at . We select analogues from a cosmological simulation with a $…
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-…
