Interstellar X-Ray Absorption and Scattering

open access: yesThe Astrophysical Journal
Accurate estimates of the absorption of X-rays by interstellar gas and dust are of crucial importance for the analysis and interpretation of almost all astronomical soft X-ray observations.

Interstellar absorption and dust scattering

open access: yes, 2022
The study of the interstellar medium (ISM) in the X-rays has entered a golden age with the advent of the X-ray observatories XMM-Newton and Chandra. High-energy resolution allowed to study dust spectroscopic features with unprecedented detail.

Pulsar Scattering as a Probe for Structures in the Interstellar Medium

open access: yesThe Astrophysical Journal
Due to the inhomogeneity of electron number density, radio waves emitted by pulsars undergo scattering as they pass through the interstellar medium (ISM).

Interstellar scattering in the inner parts of the galaxy

open access: yesNature, 1984
A new survey of the galactic plane for sources with size less than 1 arc s at 327 MHz shows that towards the inner parts of the galaxy for galactic latitudes less than 5°, interstellar scattering is much larger than expected from data at higher latitudes.

Associations between Scattering Screens and Interstellar Medium Filaments

open access: yesThe Astrophysical Journal
Pulsar scintillation can be used to measure small-scale structure in the Galaxy, but little is known about the specific interstellar medium (ISM) features that cause scintillation.

Technology requirements of exploration beyond Neptune by solar sail propulsion [PDF]

open access: yes, 2010
This paper provides a set of requirements for the technology development of a solar sail propelled Interstellar Heliopause Probe mission. The mission is placed in the context of other outer solar systems missions, ranging from a Kuiper Belt mission ...

SCATTERING OF PULSAR RADIO EMISSION BY THE INTERSTELLAR PLASMA [PDF]

open access: yesThe Astrophysical Journal, 2010
We present simulations of scattering phenomena which are important in pulsar observations, but which are analytically intractable. The simulation code, which has also been used for solar wind and atmospheric scattering problems, is available from the authors.

Low and high orders light scattering within the dispersible media. [PDF]

open access: yes, 2005
Sprays, aerosols as well as other industrially relevant turbid media can be characterized by light scattering techniques. However these techniques often fall into the intermediate scattering regime where the average number of times a photon is ...

Turbulence in the interstellar medium [PDF]

open access: yes, 2014
Turbulence is ubiquitous in the insterstellar medium and plays a major role in several processes such as the formation of dense structures and stars, the stability of molecular clouds, the amplification of magnetic fields, and the re-acceleration and ...
