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 …

The existence of∼ 109M⊙ supermassive black holes (SMBHs) within the first billion years
of the Universe has stimulated numerous ideas for the prompt formation and rapid growth of …

We present the JWST cycle 1 53.8 h medium program FRESCO, short for 'First Reionization
Epoch Spectroscopically Complete Observations'. FRESCO covers 62 arcmin2 in each of …

Abstract The Reionization Era Bright Emission Line Survey (REBELS) is a cycle-7 ALMA
Large Program (LP) that is identifying and performing a first characterization of many of the …

Hydrogen Lyman-α (Lyα) emission has been one of the major observational probes for the
high-redshift Universe since the first discoveries of high-z Lyα-emitting galaxies in the late …

The Binary Population and Spectral Synthesis suite of binary stellar evolution models and
synthetic stellar populations provides a framework for the physically motivated analysis of …

Forthcoming observational facilities will make the exploration of the early universe routine,
likely probing large populations of galaxies at very low metallicities. It will therefore be …

We discuss new Keck/MOSFIRE spectroscopic observations of four luminous galaxies at z≃
7–9 selected to have intense optical line emission by Roberts-Borsani et al. Previous follow …

Intermediate-mass black holes (IMBHs), with masses in the range 1 0 0–1 0 6 M⊙, are the
link between stellar-mass BHs and supermassive BHs (SMBHs). They are thought to be the …

We present new ALMA observations and physical properties of a Lyman break galaxy at z=
7.15. Our target, B14-65666, has a bright ultra-violet (UV) absolute magnitude, M UV≈ …
