Constraining reionization with persistent homology: a novel summary statistic for wide-field Lyman- emitter observations

Michael M. Wyatt, Nikolaos Triantafyllou, Steven R. Furlanetto +4

The spatial clustering of Lyman- emitters (LAEs) is one of the most promising observables for constraining reionization. In this work, we introduce persistent homology, a popula…

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…

Dual Signatures of Bursty Star Formation in High-Redshift UV Luminosity Functions

Guochao Sun, Claude-André Faucher-Giguère, Steven R. Furlanetto +1

The UV luminosity function (UVLF) encodes key information about galaxy formation. The slowly evolving bright-end UVLFs at have made UV variability from bursty star for…

A model to mini-quench early galaxies by balancing stellar feedback and gas accretion

Judah Luberto, Steven R. Furlanetto

The James Webb Space Telescope (JWST) has discovered a population of low-mass, early galaxies with very low levels of star formation over tens of Myr. These "mini-quenched" galaxie…

The MegaWave Radio Surveyor

T. Joseph W. Lazio, Evgenya Shkolnik, James Aguirre +40

Several Decadal-level questions in astrophysics, exoplanets, astrobiology, and cosmology can be addressed only at low radio frequencies inaccessible from Earth. The MegaWave Radio…

Searching for Population III stars with line intensity mapping cross-correlations

Sahil Hegde, Guochao Sun, Julian B. Muñoz +1

Decades of searches for Population III stars in individual galaxies have yielded a few potential candidates, but a statistically robust characterization of the demographics of the…
