We present a novel scenario for the growth of dust grains in galaxies at high-redshift (z ∼ 6). In our model, the mechanical feedback from massive star clusters evolving within high-density pre-enriched media allows to pile-up a large amount of matter into massive supershells. If the gas metallicity (≥ Z ), number density (≥ 10 cm−3) and dust-to-gas mass ratio (∼ 1/150 × Z) within the supershell are sufficiently large, such supershells may become optically thick to the starlight emerging from… Expand

Accurate dust temperature determination in a z = 7.13 galaxy
We report ALMA Band 9 continuum observations of the normal, dusty star-forming galaxy A1689-zD1 at z = 7.13, resulting in a ∼4.6 σ detection at 702 GHz. For the first time, these observations probeExpand

The problematic growth of dust in high-redshift galaxies
Dust growth via accretion of gas species has been proposed as the dominant process to increase the amount of dust in galaxies. We show here that this hypothesis encounters severe difficulties thatExpand
Stellar sources of dust in the high-redshift Universe
With the aim of investigating whether stellar sources can account for the ≥10 8 Mdust masses inferred from mm/sub-mm observations of samples of 5 <z< 6.4 quasars, we develop a chemical evolutionExpand
Maximally Dusty Star-forming Galaxies: Supernova Dust Production and Recycling in Local Group and High-redshift Galaxies
Motivated by recent observations suggesting that core-collapse supernovae may on average produce ~0.3 M_sun of dust, we explore a simple dust production scenario which applies to star-formingExpand
Production of dust by massive stars at high redshift
The large amounts of dust detected in sub-millimeter galaxies and quasars at high redshift pose a challenge to galaxy formation models and theories of cosmic dust formation. At z>6 only stars ofExpand
The dust content of QSO hosts at high redshift
Infrared observations of high-z quasar (QSO) hosts indicate the presence of large masses of dust in the early universe. When combined with other observables, such as neutral gas masses and starExpand
Fragmentation in Dusty Low-metallicity Star-forming Halos
The first stars in the universe, termed Population III, are thought to have been very massive compared to the stars that form in the present epoch. As feedback from the first generation of starsExpand

Context. The mechanism of dust formation in galaxies at high redshift is still unknown. Asymptotic giant branch (AGB) stars and explosions of supernovae (SNe) are possible dust producers, andExpand
Globular Cluster Formation at High Density: A Model for Elemental Enrichment with Fast Recycling of Massive-star Debris
The self-enrichment of massive star clusters by p-processed elements is shown to increase significantly with increasing gas density as a result of enhanced star formation rates and stellarExpand
Infrared Observational Manifestations of Young Dusty Super Star Clusters
The growing evidence pointing at core-collapse supernovae as large dust producers makes young massive stellar clusters ideal laboratories to study the evolution of dust immersed in a hot plasma. HereExpand
The infrared-dark dust content of high redshift galaxies
We present a theoretical model aimed at explaining the IRX-$\beta$ relation for high redshift (z >5) galaxies. Recent observations (Capak+2015; Bouwens+2016) have shown that early Lyman BreakExpand
