Organic Matter in Cosmic Dust. [PDF]
Organics are observed to be a significant component of cosmic dust in nearly all environments were dust is observed. In many cases only remote telescope observations of these materials are obtainable and our knowledge of the nature of these materials is very basic. However, it is possible to obtain actual samples of extraterrestrial dust in the Earth's

Sources of cosmic dust in the Earth's atmosphere. [PDF]
AbstractThere are four known sources of dust in the inner solar system: Jupiter Family comets, asteroids, Halley Type comets, and Oort Cloud comets. Here we combine the mass, velocity, and radiant distributions of these cosmic dust populations from an astronomical model with a chemical ablation model to estimate the injection rates of Na and Fe into ...

Cosmic dust evolution: The challenges for NIKA2 [PDF]
I summarize a recent study aimed at constraining dust evolution timescales in nearby galaxies. We were able to quantify the effciency of dust condensation in SN II ejecta, grain growth in the ISM and dust destruction by SN II blast waves.

Laboratory Analogues of Cosmic Dust [PDF]
Abstract Understanding the properties and the evolution of cosmic dust requires laboratory experiments for measuring basic physical and chemical data and simulating the interaction of dust grains with their cosmic environments. We give a short review of such laboratory experiments using analogue materials of cosmic dust.

Star Formation and Dust in the Cosmic Web
The large-scale environment of the cosmic web is believed to impact galaxy evolution, but there is still no consensus regarding the mechanisms. We use a semi-analytic model (SAM) galaxy catalog to study the star formation and dust content of local ...
