The Wavelength Dependence of Interstellar Extinction from 1.25 to 8.0 μm Using GLIMPSE Data [PDF]

open access: yes, 2004
We determine and tabulate A[λ]/AK, the wavelength dependence of interstellar extinction, in the Galactic plane for 1.25 μm ≤ λ ≤ 8.0 μm along two lines of sight: l = 42° and 284°.

The Optical–Mid-infrared Extinction Law of the l = 165° Sightline in the Galactic Plane: Diversity of the Extinction Law in the Diffuse Interstellar Medium [PDF]

open access: yes, 2017
Understanding the effects of dust extinction is important to properly interpret observations. The optical total-to-selective extinction ratio, , is widely used to describe extinction variations in ultraviolet and optical bands. Since the extinction curve

A Solar Analog Model for Decrease in Far Ultraviolet Irradiance Under a Grand Minimum

open access: yesEarth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Solar analog field stars having a range of magnetic activity can provide an estimate of solar spectral irradiance (SSI) variability relevant to understanding the Sun's influence on terrestrial climate. This approach is particularly useful for far ultraviolet (FUV) irradiance that cannot be observed from the Earth surface.

Modeling of Interstellar Dust Grains

open access: yes, 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 ...

Modeling the Infrared Interstellar Extinction [PDF]

open access: yes, 2014
How dust scatters and absorbs starlight in the interstellar medium (ISM) contains important clues about the size and composition of interstellar dust.

Different Frontier, Same Legal Script? On the Course of Replicating Earth's Patterns in Space

open access: yesThe Modern Law Review, Volume 89, Issue 5, Page 723-759, September 2026.
As states and private actors expand their activities in outer space, the international legal framework governing this domain risks extending longstanding structures of global inequality beyond Earth. This article examines how international space law, shaped by a broader disciplinary pattern of reactive legal development, is poised to reproduce ...

The Great Cosmic Silence: What Does the Fermi Paradox Tell About the Future of Humanity?

open access: yesGlobal Policy, Volume 17, Issue 4, Page 553-565, September 2026.
ABSTRACT This article examines how institutional time horizons shape the long‐term survival prospects of human technological civilisation. While research on global catastrophic and existential risks has expanded, the temporal structures of political‐economic institutions remain underexamined.

A measurement of interstellar polarization and an estimation of Galactic extinction for the direction of the X-ray black hole binary V404 Cygni [PDF]

open access: yes, 2016
V404 Cygni is a well-known black hole binary candidate thought to have relativistic jets. It showed extreme outbursts on June 2015, characterized by a large amplitude and short time variation of flux in the radio, optical, and X-ray bands.

Negotiating in a Foreign Land: Understanding the Curious Interactions Between Intracellular Mitochondria and Internalized Nanoparticles

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 16, 18 August 2026.
Therapeutic nano‐drug delivery systems interact with cellular mitochondria in a multitude of ways. While the complexity of such interactions disrupts the mitochondrial electron transport chain and increases reactive oxygen species production, thereby contributing to nanoparticle toxicity, they also present unique theranostic opportunities in diseases ...

Grain growth, optical polarisation, and extinction in interstellar clouds [PDF]

open access: yes, 1989
Increases in the wavelength of maximum polarization and the ratio of total to selective extinction are generally assumed to be the result of grain growth in interstellar clouds.
