First Results from HERA Phase II
The HERA Collaboration, Zuhra Abdurashidova, Tyrone Adams +83
We report the first upper limits on the power spectrum of 21-cm fluctuations during the Epoch of Reionization and Cosmic Dawn from Phase II of the Hydrogen Epoch of Reionization Ar…
Narrowing the discovery space of the cosmological 21-cm signal using multi-wavelength constraints
Jiten Dhandha, Anastasia Fialkov, Thomas Gessey-Jones +6
The cosmic 21-cm signal is a promising probe of the early Universe, owing to its sensitivity to the thermal state of the neutral intergalactic medium (IGM) and properties of the fi…
Exploiting synergies between JWST and cosmic 21-cm observations to uncover star formation in the early Universe
Jiten Dhandha, Anastasia Fialkov, Thomas Gessey-Jones +6
In the current era of JWST, we continue to uncover a wealth of information about the Universe deep into the Epoch of Reionization. In this work, we use a suite of simulations with…
LCS: An AI-based Low-Complexity Scaler for Power-Efficient Super-Resolution of Game Content
Simon Pochinda, Momen K. Tageldeen, Mark Thompson +5
The increasing complexity of content rendering in modern games has led to a problematic growth in the workload of the GPU. In this paper, we propose an AI-based low-complexity scal…
Cosmological super-resolution of the 21-cm signal
Simon Pochinda, Jiten Dhandha, Anastasia Fialkov +1
In this study, we train score-based diffusion models to super-resolve gigaparsec-scale cosmological simulations of the 21-cm signal. We examine the impact of network and training d…
Constraining the properties of Population III galaxies with multi-wavelength observations
S. Pochinda, T. Gessey-Jones, H. T. J. Bevins +7
The early Universe, spanning 400,000 to 400 million years after the Big Bang (), has been left largely unexplored as the light from luminous objects is too faint t…
