LIMFAST. V. Probing Reionization with the Synergy Between 21 cm and Photometric Galaxy Surveys

Guochao Sun, Adam Lidz, Tzu-Ching Chang +4

Cross-correlating the 21\,cm signal from intergalactic neutral hydrogen with the galaxy distribution is a powerful probe of the Epoch of Reionization and the physical mechanisms dr…

CIBER galaxy cross-correlations reveal a bright, low-redshift NIR background

Richard M. Feder, Grigory Heaton, James J. Bock +7

We perform the first tomographic analysis of near-IR extragalactic background light (EBL) anisotropies, cross-correlating CIBER 1.1 and 1.8 m imager data with photometric galaxy…

Spectral Map Making with SPHEREx

Ari J. Cukierman, Shuang-Shuang Chen, Jae Hwan Kang +24

We present map-making methodologies and preliminary spectral data cubes for SPHEREx, a NASA Explorer mission that launched in March 2025 and has been performing an all-sky near-inf…

Relatively Fast and Reasonably Furious: Evidence for Increased Burstiness in Smaller Halos at Cosmic Dawn

Julian B. Muñoz, John Chisholm, Guochao Sun +7

We introduce an effective framework to model star-formation burstiness and use it to jointly fit galaxy UV luminosity functions (UVLFs), clustering, and H/UV ratios, providing t…

The SPHEREx Satellite Mission

James J. Bock, Asad M. Aboobaker, Joseph Adamo +111

SPHEREx, a NASA explorer satellite launched on 11 March 2025, is carrying out the first all-sky near-infrared spectral survey. The satellite observes in 102 spectral bands from 0.7…

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…
