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 ...

Exploring the Interior Structure of (16) Psyche Through Basin‐Scale Collisions

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Asteroid (16) Psyche, the largest member of the M/X‐type asteroids, may be the leftover core of a differentiated planetesimal. As such (16) Psyche will be explored in detail by NASA's discovery‐class Psyche mission in 2029. This will be the first mission to orbit a metal‐rich asteroid, or any asteroid in the 100–500 km size range.

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.

Integrated heterodyne array receivers for submillimeter astronomy [PDF]

SPIE Proceedings, 2003
The advent of large format (~100 pixel) spectroscopic imaging cameras at submillimeter wavelengths would fundamentally change the way in which astronomy is performed in this important wavelength regime. While the possibility of such instruments has been discussed for more than two decades, only recently have advances in mixer technology, device ...

Differentiating Plumes and Local Torus Segments of Enceladus

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Enceladus's south polar plumes and their surrounding torus segments (local plasma regions formed by plume material diffusion) are key to understanding its magnetospheric interaction; however, clear observational criteria to distinguish them remain lacking.

Self‐Healing Materials from Electronically Integrated Microscopic Robots

Advanced Intelligent Systems, Volume 8, Issue 1, January 2026.
Submillimeter robots can use electronically controlled electrodeposition to assemble into a material structure. The resulting aggregate possesses ultralow density, high strength‐to‐weight ratio, and can heal from damage. Further afield, these results clear a path to materials that organize or adapt by directing matter and information at the microscale.

Magnetic Resonance Neurography of the Brachial Plexus at 1.5 T: Diagnostic Reliability and Time Efficiency of Bilateral Ultra‐Fast 3D STIR vs. Unilateral 2D Dixon

International Journal of Imaging Systems and Technology, Volume 36, Issue 1, January 2026.
ABSTRACT Recent technological advancements may now allow shorter reliable magnetic resonance neurography (MRN) scans of the brachial plexus (BP) even at 1.5 T. The objective of this study was to compare ultra‐fast bilateral coronal 3D T2w TSE STIR (3D‐IR) with unilateral sagittal 2D T2w TSE Dixon (2D‐DX) in terms of image quality, diagnostic ...

Jets in Low-Mass Protostars

Universe
Jets and outflows are key components of low-mass star formation, regulating accretion and shaping the surrounding molecular clouds. These flows, traced by molecular species at (sub)millimeter wavelengths (e.g., CO, SiO, SO, H2CO, and CH3OH) and by atomic,

The Quest for the Missing Dust. II. Two Orders of Magnitude of Evolution in the Dust-to-gas Ratio Resolved within Local Group Galaxies

The Astrophysical Journal, 2023
We explore evolution in the dust-to-gas ratio with density within four well-resolved Local Group galaxies—the LMC, SMC, M31, and M33. We do this using new Herschel maps, which restore extended emission that was missed by previous Herschel reductions ...

A Cross‐Correlation Method to Evaluate Wind Retrieval Accuracy on Mars Using Simulated Microwave Limb Sounder Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract While aspects such as the temperature and composition of the Martian atmosphere are relatively well known thanks to observations from numerous space missions, Martian atmospheric dynamics remain poorly constrained due to the scarcity of direct wind measurements. The use of microwave limb sounders to retrieve winds has been proposed in the past,
