The first generation of stars, often called Population III (or Pop III), form from metal-free
primordial gas at redshifts z∼ 30 and below. They dominate the cosmic star-formation …

Spurred by rich, multiwavelength observations and enabled by new simulations, ranging
from cosmological to subparsec scales, the past decade has seen major theoretical …

Abstract LiteBIRD, the Lite (Light) satellite for the study of B-mode polarization and Inflation
from cosmic background Radiation Detection, is a space mission for primordial cosmology …

ABSTRACT A substantial number of ultra-high redshift (8≲ z≲ 17) galaxy candidates have
been detected with JWST, posing the question: Are these observational results surprising in …

We identify a low-metallicity () Ly-emitting galaxy at with evidence of a strong Balmer jump,
arising from nebular continuum. While Balmer jumps are sometimes observed in low-redshift …

Galaxy formation is at the heart of our understanding of cosmic evolution. Although there is a
consensus that galaxies emerged from the expanding matter background by gravitational …

Recent observations with JWST have identified several bright galaxy candidates at z≳ 10,
some of which appear unusually massive (up to∼ 10 11 M⊙). Such early formation of …

The Square Kilometre Array (SKA) is a planned large radio interferometer designed to
operate over a wide range of frequencies, and with an order of magnitude greater sensitivity …

We propose a space-based interferometer surveying the gravitational wave (GW) sky in the
milli-Hz to μ-Hz frequency range. By the 2040s, the μ-Hz frequency band, bracketed in …

Line-intensity map** (LIM) is an emerging approach to survey the Universe, using
relatively low-aperture instruments to scan large portions of the sky and collect the total …
