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…
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…
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…
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…
