No way ou: Epoch of Reionization Observations Do not Support Large Values of the Optical Depth to Reionization

Paulo Montero-Camacho, Yi Mao

The authors combine CMB data (excluding large‑scale polarization), BAO measurements, and quasar‑based reionization observations to estimate the optical depth to reionization as τ≈0…

Foreground Characterization and Mitigation in the Observations of the CD/EoR with the SKA

Philip Bull, Jacob Burba, Emilio Ceccotti +20

The Square Kilometre Array (SKA), with its unprecedented sensitivity, frequency coverage, and large collecting area, is poised to revolutionize our understanding of the Cosmic Dawn…

Overview of 21cm Experiments at high redshift with SKAO

CD Science Working Group, Gianni Bernardi, Daniela Breitman +81

We provide an overview of the eight SKAO Science Book chapters that motivate the Epoch of Reionisation and Cosmic Dawn experiments with SKA-Low. We describe the individual SKA-Low…

Tantalizing Evidence of Reionization Relics in the eBOSS DR16 Ly Forest Correlations: a Preference for Early Reionization

Yifan Zheng, Paulo Montero-Camacho, Zheng Cai +1

Cosmic reionization of HI leaves enduring relics in the post-reionization intergalactic medium, potentially influencing the Lyman- (Ly) forest down to redshifts as low as $…

Multi-fidelity emulator for large-scale 21 cm lightcone images: a few-shot transfer learning approach with generative adversarial network

Kangning Diao, Yi Mao

Emulators using machine learning techniques have emerged to efficiently generate mock data matching the large survey volume for upcoming experiments, as an alternative approach to…

Constraining fuzzy dark matter with the 21-cm power spectrum from Cosmic Dawn and Reionization

Shihang Liu, Yilin Liu, Bowen Peng +4

The 21-cm signals from Cosmic Dawn and the Epoch of Reionization contain valuable information on cosmological structure formation dominated by dark matter. Measurements of the 21-c…
