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…
