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).

Structure and evolution of interstellar carbonaceous dust. Insights from the laboratory
Frontiers in Astronomy and Space Sciences, 2022 A large fraction of interstellar carbon is locked up in solid grains. The nature, origin and evolution of these grains have been investigated for decades.

C$^+$ detection of warm dark gas in diffuse clouds [PDF]
, 2010 We present the first results of the Herschel open time key program, Galactic Observations of Terahertz C$^+$ (GOT C+) survey of the [CII] fine-structure line at 1.9 THz (158 microns) using the HIFI instrument on Herschel.

Confined Chemistry in Space: Zeolite‐Supported Fe13 Nanoclusters Modulate CS Reactivity
Small Structures, Volume 7, Issue 3, March 2026.The study explores how an Fe13 cluster confined in chabazite reshapes the reaction of CS and H2 under astrochemical conditions. Confinement promotes C–S bond cleavage over hydrogenation, directing chemistry toward CH4 and H2S formation. Additional CS enables CS2 and C2 species. Microkinetic analysis identifies protoplanetary environments where zeolites

Life Cycle of Dust in the Magellanic Clouds and the Milky Way
, 2014 To a great extent, our understanding of the life cycle of dust is based on the observational and theoretical studies of the Milky Way and the Magellanic Clouds, which will be the topic of this contribution. Over past years, a large volume of observations

The kinetic chemistry of dense interstellar clouds
The Astrophysical Journal Supplement Series, 1982 A model of the time-dependent chemistry of dense interstellar clouds is formulated to study the dominant chemical processes in carbon and oxygen isotope fractionation, the formation of nitrogen-containing molecules, and the evolution of product molecules as a function of cloud density and temperature.

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract 10Be deposition in ice cores is widely used for solar reconstructions, but its interpretation is complicated by volcanic influences. Using the state‐of‐the‐art aerosol‐climate model ECHAM6.3‐HAM2.3‐SALSA2.0: 10Be, we assess the impacts of three major volcanic eruptions: Agung (1963), El Chichón (1982) and Pinatubo (1991). All eruptions enhance

Small Structures, Volume 7, Issue 2, February 2026.This work describes how to conceive validated mixed machine learned/empirical energy functions based on finite‐sized molecular clusters for condensed phase simulations. Energy functions for pure and heterogeneous systems are one of the backbones for molecular simulation of condensed phase systems.
