Fault‐Related Carbonates as Quaternary Seismotectonic and Paleoclimate Archives (Monte Marine Fault, Central Apennines)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Seismogenic faults shape continental landscapes, drive crustal deformation and influence fluid exchange between the lithosphere and atmosphere. Yet, quantitative links between fault activity, exhumation and near‐surface environmental evolution remain poorly understood. Here, structural (meso‐ and micro‐scale) investigations are integrated with

Early infrared astronomy

, 2009
International audienceI present a short history of infrared astronomy, from the first scientific approaches of the `radiant heat' in the seventeenth century to the 1970's, the time when space infrared astronomy was developing very rapidly.

The JCMT Legacy Release: SCUBA-2 850 μm Coadds and Catalogs

The Astrophysical Journal Supplement Series
We present the James Clerk Maxwell Telescope (JCMT) 850 μ m Legacy Release, containing uniformly reduced, coadded tiles, and catalogs of detected emission, for the 850 μ m data from all Submillimetre Common User Bolometer Array 2 (SCUBA-2) observations ...

Stratigraphic Partitioning of Evaporites Through the Clay‐Sulfate Transition in Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Changing surface conditions on Mars during the Hesperian eon (∼3.6–3.0 billion years ago) produced widespread stratal sequences transitioning from clay to sulfate‐bearing according to orbital data. Using data collected in situ at Gale crater by the Curiosity rover, we examined both the sedimentology and geochemistry of a 210‐m‐thick succession

An Improved Upper Limit of Cyanodiacetylene (HC5N) in the Atmosphere of Titan

The Astronomical Journal
In the complex Titan atmospheric chemistry, photochemical reactions involving cyanodiacetylene (HC _5 N) may be important as reaction pathways that could lead to the production of amines and aromatic molecules.

Tertiary‐Ozone‐Maximum‐Like Mesospheric Ozone Increases Driven by Solar Eclipses: Sensitivity Experiments on WACCM‐X

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Solar eclipses offer natural experiments to isolate the photochemical response of mesospheric ozone to solar radiation. Using the WACCM‐X model, we performed mechanism‐oriented sensitivity experiments for the 14 December 2020 eclipse to quantify the tertiary‐ozone‐maximum‐like (TOM‐like) response.

Advanced aqueous alteration in primitive meteorites: Micro‐ to nanoscale studies of CR1 iron sulfides

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1806-1825, August 2026.
Abstract This study documents micro‐ to nanoscale observations of primary nebular and secondary parent body iron sulfides in the CR1 GRO 95577. Despite the extensive alteration of the bulk sample, some primary sulfides managed to avoid alteration, having originally formed in the solar nebula during chondrule formation by either fission‐sulfidization or

The role of composition in the spectral evolution of carbonaceous asteroids as informed by Bennu sample return

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1875-1904, August 2026.
Abstract Near‐Earth rubble‐pile asteroids Bennu and Ryugu are part of the carbonaceous taxonomic complex (C‐complex), and samples returned from both bodies resemble the most aqueously altered carbonaceous chondrites. However, telescopic and spacecraft visible–near infrared (VIS–NIR) reflectance spectra of Ryugu exhibit a red (positive) spectral slope ...

Dust Properties of 870 μm-selected Galaxies in GOODS-S

The Astrophysical Journal, 2023
We analyze the dust properties of 57 870 μ m-selected dusty star-forming galaxies in GOODS-S using new deep Atacama Large Millimeter/Submillimeter Array 1.2, 2, and 3 mm continuum imaging together with other far-infrared through millimeter data.
