A Model Connecting Galaxy Masses, Star Formation Rates, and Dust Temperatures Across Cosmic Time
We investigate the evolution of dust content in galaxies from redshifts z=0 to z=9.5. Using empirically motivated prescriptions, we model galactic-scale properties -- including halo mass, stellar mass, star formation rate, gas mass, and metallicity -- to

DESTRUCTION OF INTERSTELLAR DUST IN EVOLVING SUPERNOVA REMNANT SHOCK WAVES [PDF]
Supernova generated shock waves are responsible for most of the destruction of dust grains in the interstellar medium (ISM). Calculations of the dust destruction timescale have so far been carried out using plane parallel steady shocks, however, that ...

The Near-infrared Extinction Law at High and Low Galactic Latitudes
The Milky Way dust extinction curve in the near-infrared (NIR) follows a power-law form, but the value of the slope, β _NIR , is debated. Systematic variations in the slope of the Milky Way UV extinction curve are known to be correlated with variations ...

Dust production scenarios in galaxies at z ~ 6-8.3
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 non-stellar processes may substantially contribute to dust production ...

Clusters Stagnating During Condensation: Metastable Material or a Separate State of Matter?
Condensation stagnation, that is, the existence of a delay between nucleation and growth during the gas‐phase particle formation, is a crucial phenomenon, which manifests itself as the presence of supercritical clusters in resulting particulates. The light emission signature of stagnant clusters is identified in the magnesium particle flame in air, and,

NEW ULTRAVIOLET EXTINCTION CURVES FOR INTERSTELLAR DUST IN M31 [PDF]
New low-resolution UV spectra of a sample of reddened OB stars in M31 were obtained with the Hubble Space Telescope/STIS to study the wavelength dependence of interstellar extinction and the nature of the underlying dust grain populations.

INTERSTELLAR DUST CHARGING IN DENSE MOLECULAR CLOUDS: COSMIC RAY EFFECTS [PDF]
The local cosmic-ray (CR) spectra are calculated for typical characteristic regions of a cold, dense molecular cloud to investigate two mechanisms of dust charging that have, thus far, been neglected: the collection of suprathermal CR electrons and ...

Algae Protein Creates Sustainable Alternatives for Various Food Matrices: From Function to Nutrition
Abstract Protein deficiency and environmental deterioration are pressing and complex issues in traditional agriculture system. Algae, which can grow without the need of land and with minimal water, offer a rich source of protein. Recently, large‐scale algae cultivation and advanced extraction techniques have been developed, positioning algae protein as

The presence of dust in the general interstellar medium is inferred from the extinction, polarization, and scattering of starlight; the presence of dark nebulae; interstellar depletions; the observed infrared emission around certain stars and various ...
