Interstellar extinction from photometric surveys: application to four high-latitude areas [PDF]

Open Astronomy, 2018
Information on interstellar extinction and dust properties may be obtained from modern large photometric surveys data. Virtual Observatory facilities allow users to make a fast and correct cross-identification of objects from various surveys. It yields a

Ultraviolet Interstellar Extinction toward High Galactic Latitudes

The Astrophysical Journal
Nearby high Galactic latitude clouds provide a unique laboratory to study the physics and structure of the Galactic interstellar medium and the properties of the interstellar dust.

DIBs, interstellar dust, and extinction [PDF]

, 2014
The relationship between DIBs and dust is still unknown. The correlation between reddening and DIB strength means that the DIBs are mixed in with the dust and gas in interstellar clouds. The DIBs are relatively stronger in the diffuse interstellar medium

New Candidate Massive Clusters from 2MASS [PDF]

, 2013
Massive stars are important for the evolution of the interstellar medium. The detailed study of their properties (such as mass loss, rotation, magnetic fields) is enormously facilitated by samples of these objects in young massive galactic star clusters.

Interstellar Silicon Depletion and the Ultraviolet Extinction [PDF]

, 2017
Spinning small silicate grains were recently invoked to account for the Galactic foreground anomalous microwave emission. These grains, if present, will absorb starlight in the far ultraviolet (UV).

New ultraviolet extinction curves for interstellar dust in M31 [PDF]

, 2015
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.

Modeling of Interstellar Dust Grains

, 2008
Dust has two major effects on light passing through the Interstellar Medium - Interstellar Extinction and Reddening. Interstellar dust grains are typically a fraction of a micron, approximately the wavelength of blue light and hence light passing ...

High spatial resolution galactic 3D extinction mapping with IPHAS [PDF]

, 2008
We present an algorithm (MEAD, for 'Mapping Extinction Against Distance') which will determine intrinsic (r' - i') colour, extinction, and distance for early-A to K4 stars extracted from the IPHAS r'/ i'/H alpha photometric data base.

On the Variation of Interstellar Dust Extinction [PDF]

Dust obscures astronomical observations and plays a important role in the evolution of galaxies. Mapping dust in three dimensions not only allows accurate correction of observations but also constrains the evolution of the interstellar medium (ISM ...
