Journal ArticleDOI
Thermal and fragmentation properties of star-forming clouds in low-metallicity environments
TL;DR: In this article, the authors studied the thermal and chemical evolution of star-forming clouds for different gas metallicities, Z, using the model of Omukai, updated to include deuterium chemistry and the effects of cosmic microwave background (CMB) radiation.
Journal ArticleDOI
First Stars, Very Massive Black Holes, and Metals
TL;DR: In this paper, the mass fraction of pair-unstable supernovae (SNs) is estimated to be the dominant sources of the first heavy elements in the early universe.
Journal ArticleDOI

TL;DR: In this article, the first results of a project, Lyman-break galaxies Stellar populations and Dynamics (LSD), aimed at obtaining spatially resolved, near-infrared (IR) spectroscopy of a complete sample of Lyman break galaxies at z ∼ 3.
Journal ArticleDOI
Dust formation and survival in supernova ejecta
TL;DR: In this paper, the authors revisited the model of Todini & Ferrara (2001) for dust formation in the ejecta of core collapse SNe and followed the evolution of newly condensed grains from the time of formation to their survival through the passage of the reverse shock in the SN remnant.
Journal ArticleDOI
Fragmentation of star-forming clouds enriched with the first dust
TL;DR: In this article, a model for the evolution of star forming clouds enriched by metals and dust from the first supernovae (SNe), resulting from the explosions of metal-free progenitors with masses in the range 12-30 M and 140-260 M, was presented.
