The cosmic dust rate across the Universe [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 We investigate the evolution of interstellar dust in the Universe by means of chemical evolution models of galaxies of different morphological types, reproducing the main observed features of present day galaxies. We adopt the most updated prescriptions for dust production from supernovae and asymptotic giant branch (AGB) stars as well as for dust ...

Synthesis and Characterization of Polypyrrole-Coated Anthracene Microparticles: A New Synthetic Mimic for Polyaromatic Hydrocarbon-Based Cosmic Dust. [PDF]
ACS Appl Mater Interfaces, 2021 Polyaromatic hydrocarbons (PAHs) are found throughout the universe. The ubiquity of these organic molecules means that they are of considerable interest in the context of cosmic dust, which typically travels at hypervelocities (>1 km s–1) within our ...

The DNA of Bacteria of the World Ocean and the Earth in Cosmic Dust at the International Space Station. [PDF]
ScientificWorldJournal, 2018 Cosmic dust samples from the surface of the illuminator of the International Space Station (ISS) were collected by a crew member during his spacewalk. The sampler with tampon in a vacuum container was delivered to the Earth.

Carbonaceous dust grains seen in the first billion years of cosmic time [PDF]
Nature, 2023 An (ultraviolet) dust attenuation feature at 2,175 Å, attributed to carbonaceous dust grains in the Milky Way and nearby galaxies, also exists in galaxies up to a redshift of 7. Large dust reservoirs (up to approximately 10^8 M _⊙) have been detected^ 1

Physics and Chemistry on the Surface of Cosmic Dust Grains: A Laboratory View [PDF]
, 2021 Dust grains play a central role in the physics and chemistry of cosmic environments. They influence the optical and thermal properties of the medium due to their interaction with stellar radiation; provide surfaces for the chemical reactions that are ...

The REBELS ALMA Survey: cosmic dust temperature evolution out to z $\sim$ 7 [PDF]
, 2022 ALMA observations have revealed the presence of dust in the first generations of galaxies in the Universe. However, the dust temperature $T_d$ remains mostly unconstrained due to the few available FIR continuum data at redshift $z>5$.

The ALMA REBELS Survey: The Dust-obscured Cosmic Star Formation Rate Density at Redshift 7 [PDF]
, 2022 Cosmic dust is an essential component shaping both the evolution of galaxies and their observational signatures. How quickly dust builds up in the early Universe remains an open question that requires deep observations at (sub-)millimeter wavelengths to ...

The Origin of Parity Violation in Polarized Dust Emission and Implications for Cosmic Birefringence [PDF]
Astrophysical Journal, 2021 Recent measurements of Galactic polarized dust emission have found a nonzero TB signal, a correlation between the total intensity and the B-mode polarization component. We present evidence that this parity-odd signal is driven by the relative geometry of

The origin of dust in galaxies across cosmic time [PDF]
Monthly notices of the Royal Astronomical Society, 2020 We study the dust evolution in galaxies by implementing a detailed dust prescription in the SAGE semi-analytical model (SAM) for galaxy formation. The new model, called Dusty SAGE, follows the condensation of dust in the ejecta of Type II supernovae ...
