Probing the Distinct Extinction Law of the Pillars of Creation in M16 with JWST
The Astrophysical Journal LettersInvestigating the extinction law in regions of high dust extinction, such as the Pillars of Creation within the M16 region, is crucial for understanding the densest parts of the interstellar medium (ISM).

The Optical Extinction Law Depends on Magnetic Field Orientation: The RV–ψ Relation
The Astrophysical JournalFor aspherical interstellar dust grains aligned with their short axes preferentially parallel to the local magnetic field, the amount of extinction per grain is larger when the magnetic field is along the line of sight and smaller when in the plane of ...

Lactea: Web‐Based Spectrum‐Preserving Multi‐Resolution Visualization of the GAIA Star Catalog
Computer Graphics Forum, Volume 44, Issue 3, June 2025.Abstract The explosion of data in astronomy has resulted in an era of unprecedented opportunities for discovery. The GAIA mission's catalog, containing a large number of light sources (mostly stars) with several parameters such as sky position and proper motion, is playing a significant role in advancing astronomy research and has been crucial in ...

Modelling interstellar extinction in three dimensions [PDF]
, 2004 We have developed a technique that estimates the threedimensional extinction in the Galactic plane. The colour distribution (J-K) of stars from the Two Micron All Sky Survey (2MASS) are compared to that of stars from the Besançon model of the Galaxy, to ...

Modeling of Interstellar Dust Grains [PDF]
, 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 ...

An Empirical Extinction Curve Revealed by Gaia XP Spectra and LAMOST
The Astrophysical JournalWe present a direct measurement of extinction curves using corrected Gaia XP spectra of the common sources in Gaia DR3 and LAMOST DR7. Our analysis of approximately 370,000 high-quality samples yielded a high-precision average extinction curve for the ...

Interstellar extinction: a parametrical study by using laboratory data [PDF]
, 1993 In this paper we present a comparative study between laboratory data, astronomical observations and theoretical models in order to provide a contribution to the characterization of cosmic-dust properties.

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 ...
