Inferring the astrophysics of reionization and cosmic dawn from galaxy luminosity functions and the 21-cm signal
Jaehong Park, Andrei Mesinger, Bradley Greig +1
The properties of the first galaxies, expected to drive the Cosmic Dawn (CD) and the Epoch of Reionization (EoR), are encoded in the 3D structure of the cosmic 21-cm signal. Parame…
Constraints on reionisation from the z=7.5 QSO ULASJ1342+0928
Bradley Greig, Andrei Mesinger, Eduardo Bañados
The recent detection of ULASJ1342+0928, a bright QSO at , provides a powerful probe of the ionisation state of the intervening intergalactic medium, potentially allowing us…
Results from EDGES High-Band: II. Constraints on Parameters of Early Galaxies
Raul A. Monsalve, Bradley Greig, Judd D. Bowman +5
We use the sky-average spectrum measured by EDGES High-Band ( MHz) to constrain parameters of early galaxies independent of the absorption feature at ~MHz reported by B…
HI 21cm Cosmology and the Bi-spectrum: Closure Diagnostics in Massively Redundant Interferometric Arrays
C. L. Carilli, Bojan Nikolic, Nithyanandan Thyagarajan +62
New massively redundant low frequency arrays allow for a novel investigation of closure relations in interferometry. We employ commissioning data from the Hydrogen Epoch of Reioniz…
Deep learning from 21-cm tomography of the Cosmic Dawn and Reionization
Nicolas Gillet, Andrei Mesinger, Bradley Greig +2
The 21-cm power spectrum (PS) has been shown to be a powerful discriminant of reionization and cosmic dawn astrophysical parameters. However, the 21-cm tomographic signal is highly…
The HERA-19 Commissioning Array: Direction Dependent Effects
Saul A. Kohn, James E. Aguirre, Paul La Plante +64
Foreground power dominates the measurements of interferometers that seek a statistical detection of highly-redshifted HI emission from the Epoch of Reionization (EoR). The chromati…
