We investigate the sources and amount of dust in early galaxies. We discuss dust nucleation in stellar atmospheres using published extended atmosphere models, stellar evolution tracks and nucleation conditions. The thermally pulsating asymptotic giant branch phase of intermediate-mass stars is likely to be the most promising site for dust formation in stellar winds. We present an elementary model including dust formation time-scales in which the amount of dust in the interstellar medium is… 
Dust production scenarios in galaxies at z ∼6–8.3
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, and
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 of
Dust Formation in Milky Way-like Galaxies
We introduce a dust model for cosmological simulations implemented in the moving-mesh code AREPO and present a suite of cosmological hydrodynamical zoom-in simulations to study dust formation within
Dust in the early Universe: evidence for non-stellar dust production or observational errors?
Observations have revealed unexpectedly large amounts of dust in high-redshift galaxies and its origin is still much debated. Valiante et al. suggested the net stellar dust production of the quasar
The dust budget crisis in high-redshift submillimetre galaxies
We apply a chemical evolution model to investigate the sources and evolution of dust in a sample of 26 high-redshift (z > 1) submillimetre galaxies (SMGs) from the literature, with complete
Genesis and evolution of dust in galaxies in the early Universe - I. Modelling dust evolution in starburst galaxies
Aims. The aim is to elucidate the astrophysical conditions required for generating large amounts of dust in massive starburst galaxies at high redshift. Methods. We have developed a numerical

In this letter we construct a large sample of early-type galaxies (ETGs) with measured gas-phase metallicities from the Sloan Digital Sky Survey and Galaxy Zoo in order to investigate the origin of
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 evolution
The origin of dust in galaxies revisited: the mechanism determining dust content
The origin of cosmic dust is a fundamental issue in planetary science. This paper revisits the origin of dust in galaxies, in particular, in the Milky Way, by using a chemical evolution model of a
The Evolution of Dust in the Early Universe with Applications to the Galaxy SDSS J1148+5251
Dusty hyperluminous galaxies in the early universe provide unique environments for studying the role of massive stars in the formation and destruction of dust. At redshifts above ~6, when the


Effects of dust grains on early galaxy evolution
Stars form out of molecular gas and supply dust grains during their last evolutionary stages; in turn hydrogen molecules (H2) are produced more efficiently on dust grains. Therefore, dust can
The Evolution of the Elemental Abundances in the Gas and Dust Phases of the Galaxy
We present models for the evolution of the elemental abundances in the gas and dust phases of the interstellar medium (ISM) of our Galaxy by generalizing standard models for its dynamical and
The Formation of Massive Stars from Turbulent Cores
Observations indicate that massive stars in the Galaxy form in regions of very high surface density, � � 1 gc m � 2 . Clusters containing massive stars and globular clusters have a column density
Massive Binary WR 112 and Properties of Wolf-Rayet Dust
Some hot, massive, Population I Wolf-Rayet (W-R) stars of the carbon subclass are known to be prolific dust producers. How dust can form in such a hostile environment remains a mystery. Here we
Chemical Evolution of Galaxies
The chemical evolution of disk galaxies is discussed with special reference to results obtained from studies of the oxygen abundance in H II regions. Normal spirals (including our own) display the by
On the Role of Massive Stars in the Support and Destruction of Giant Molecular Clouds
We argue that massive stars are the dominant sources of energy for the turbulent motions within giant molecular clouds and that the primary agent of feedback is the expansion of H II regions within
Dust Formation in Primordial Type II Supernovae
We have investigated the formation of dust in the ejecta of Type II supernovae (SNe), mostly of primordial composition, to answer the question of where are the first solid particles formed in the
Dust in the Tycho, Kepler and Crab supernova remnants
SuperNova Remnants (SNR) have been extensively studied in radio, X-rays and optical, but barely in the InfraRed (IR). From IRAS observations, SNR are known to be IR emitters, but the origin of the
Sources of Stardust in the Galaxy
Observed mass loss rates and Galactic stellar population distributions are used to estimate the rate of injection of stardust into the ISM. M stars and RLOH/IR Stars produce most of the silicates;
Newly Synthesized Elements and Pristine Dust in the Cassiopeia A Supernova Remnant
Spectroscopic observations at 2.4-45 μm of the young supernova remnant Cas A with the Infrared Space Observatory (ISO) Short Wavelength Spectrometer reveal strong emission lines of O, Ne, Si, S, and
