Low temperature MIR to submillimeter mass absorption coefficient of interstellar dust analogues [PDF]
A wealth of data from the Herschel and Planck satellites and now from ALMA, revealing cold dust thermal emission, is available for astronomical environments ranging from interstellar clouds, cold clumps, circumstellar envelops, and protoplanetary disks ...

The Power of the Rings: The GRB 221009A Soft X-Ray Emission from Its Dust-scattering Halo
GRB 221009A is the brightest gamma-ray burst (GRB) ever detected that has occurred at low Galactic latitude. Owing to this exceptional combination, its prompt X-ray emission could be detected for weeks in the form of expanding X-ray rings produced by ...

Depletion patterns and dust evolution in the ISM [PDF]
We review the use of elemental depletions in determining the composition of interstellar dust and present a new interpretation of the elemental depletion patterns for the dust forming elements in a range of diffuse cloud types. We discuss this within the

The Herschel Virgo Cluster Survey: VII. Dust in cluster dwarf elliptical galaxies [PDF]
We use the Science Demonstration Phase data of the Herschel Virgo Cluster Survey to search for dust emission of early-type dwarf galaxies in the central regions of the Virgo Cluster as an alternative way of identifying the interstellar medium.We present ...

Dust in protoplanetary disks: observations*
Solid particles, usually referred to as dust, are a crucial component of interstellar matter and of planet forming disks surrounding young stars. Despite the relatively small mass fraction of ≈1% (in the solar neighborhood of our galaxy; this number may ...

Dust evolution in pre-stellar cores [PDF]
Dust grains are the building blocks of future planets. They evolve in size, shape and composition during the life cycle of the interstellar medium. We seek to understand the process which leads from diffuse medium grains to dust grains in the vicinity of

ORGANIC DUST IN THE INTERSTELLAR MEDIUM [PDF]
The traditional view of dust in the interstellar medium is that it is made of graphite and silicates. In this paper, we discuss the evidence for complex organics being a major component of interstellar dust. Comparison between astronomical infrared spectra and laboratory spectra of amorphous carbonaceous materials suggests that organics of mixed ...

Comet Dust: Connections with Interstellar Dust [PDF]
The Comet Halley campaigns resulted in an enormously better understanding of the composition of comets. Silicates, organic compounds, and volatile ices comprised ofH2O, CO, CO2,S2,CN, and possiblyCH4andOCSoccur in comet grains. These are all known or suspected constituents of interstellar dust.

Thermal and non-thermal dust sputtering in hydrodynamical simulations of the multiphase interstellar medium [PDF]
We study the destruction of interstellar dust via sputtering in supernova (SN) shocks using three-dimensional hydrodynamical simulations. With a novel numerical framework, we follow both sputtering and dust dynamics governed by direct collisions, plasma ...
