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 formation of the first galaxies during cosmic dawn and reionization (at redshifts z= 5–
30), triggered the last major phase transition of our universe, as hydrogen evolved from cold …

We estimate the 21 cm radio background from accretion onto the first intermediate-mass
black holes between z≈ 30 and z≈ 16. Combining potentially optimistic, but plausible …

In this review article, we briefly outline our current understanding of the physics associated
with the HI 21-cm signal from cosmic dawn. We discuss different phases of cosmic dawn as …

ABSTRACT The Experiment to Detect the Global Epoch of Reionization Signature (EDGES)
recently reported a strong 21-cm absorption signal relative to the cosmic microwave …

The semianalytical model a-sloth (Ancient Stars and Local Observables by Tracing Halos) is
the first public code that connects the formation of the first stars and galaxies to observables …

Despite extensive search efforts, direct observations of the first [Population III (Pop III)] stars
have not yet succeeded. Theoretical studies have suggested that late Pop III star formation is …

We construct a theoretical framework to study Population III (Pop III) star formation in the post-
reionization epoch (z≲ 6) by combining cosmological simulation data with semi-analytical …

The formation of Population III (Pop III) stars is a critical step in the evolution of the early
Universe. To understand how these stars affected their metal-enriched descendants, the …

The first stars, galaxies, star clusters, and direct-collapse black holes are expected to have
formed in low-mass (∼ 105–109 M⊙) haloes at Cosmic Dawn (z∼ 10–30) under conditions …
