Inferring Cosmology and Astrophysics from the High-redshift 21cm Signal with SKA-Low
Anshuman Acharya, Satadru Bag, Sabrina Berger +29
The Square Kilometre Array's low frequency telescope (SKA-Low) will enable inference of astrophysical and cosmological parameters from the redshifted 21 cm signal, probing the Cosm…
21cmEMUv3: a hybrid diffusion-LSTM emulator of 21cmFAST summary observables
Daniela Breitman, Andrei Mesinger, Steven G. Murray +2
We are witnessing a surge in observations of the cosmic dawn (CD) and epoch of reionisation (EoR), driving an increasing demand for fast and robust theoretical interpretation frame…
Sample Variance Denoising in Cylindrical 21-cm Power Spectra
Daniela Breitman, Andrei Mesinger, Steven G. Murray +1
State-of-the-art simulations of reionisation-era 21-cm signal have limited volumes, generally orders of magnitude smaller than observations. Consequently, the Fourier modes in comm…
Efficient simulation of discrete galaxy populations and associated radiation fields during the first billion years
James E. Davies, Andrei Mesinger, Steven Murray
Understanding the epochs of cosmic dawn and reionisation requires us to leverage multi-wavelength and multi-tracer observations, with each dataset providing a complimentary piece o…
