The space infrared telescope for cosmology and astrophysics SPICA: A joint mission between JAXA and ESA

open access: yes, 2008
International audienceThe Space Infrared telescope for Cosmology and Astrophysics (SPICA) is planned to be the next space astronomy mission observing in the infrared. The mission is planned to be launched in 2017 and will feature a 3.5 m telescope cooled

Synthesis and Characterization of Highly Conductive Cobalt Phthalocyanine‐Based Metal–Organic Framework

open access: yesAdvanced Electronic Materials, EarlyView.
A two‐dimensional (2D) layered material, CoPc‐MOF, with a cobalt phthalocyanine backbone as its structural unit, was successfully synthesized. CoPc‐MOF adopts a crystal structure analogous to a Lieb lattice, which is a type of Dirac material. CoPc‐MOF exhibits exceptionally high electrical conductivity for an organic semiconductor, which likely ...

PGC 44685: A Dwarf Star-forming Lenticular Galaxy with a Wolf–Rayet Population

open access: yesThe Astrophysical Journal
Lenticular galaxies (S0s) are formed mainly from the gas stripping of spirals in the cluster. But how S0s form and evolve in the field is still in need of being resolved.

Where within the 3C 84 jet are γ-rays produced?

open access: yesAstronomy & Astrophysics
The location in which γ-ray are created and emitted within extra-galactic jets is a matter of active debate. One particularly well-suited source for determining the location is the nearby bright radio galaxy 3C 84, harbouring a powerful jet.

A Kinetic–Energetic Bottleneck of Charge‐Transfer Injection Governs Energy Loss in Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Kinetic–energetic projection of time‐resolved photoluminescence reveals that charge‐transfer injection acts as a universal bottleneck in organic solar cells. A physics‐constrained Bayesian framework identifies an emergent effective CT injection rate governing the trade‐off between charge generation and nonradiative energy loss.

Automatic Determination of Quasicrystalline Patterns from Microscopy Images

open access: yesAdvanced Intelligent Discovery, EarlyView.
This work introduces a user‐friendly machine learning tool to automatically extract and visualize quasicrystalline tiling patterns from atomically resolved microscopy images. It uses feature clustering, nearest‐neighbor analysis, and support vector machines. The method is broadly applicable to various quasicrystalline systems and is released as part of

A Successful Sheared-arcade Eruption Triggered by a Failed Erupted Small Filament

open access: yesThe Astrophysical Journal
In this work, we analyze a successful eruption, accompanied by an X5.4-class flare in active region 11429. The eruptive structure is an elongated hot structure, with two curved brightenings below it.

Deep Learning‐Assisted Coherent Raman Scattering Microscopy

open access: yesAdvanced Intelligent Discovery, EarlyView.
The analytical capabilities of coherent Raman scattering microscopy are augmented through deep learning integration. This synergistic paradigm improves fundamental performance via denoising, deconvolution, and hyperspectral unmixing. Concurrently, it enhances downstream image analysis including subcellular localization, virtual staining, and clinical ...

Abundant Molecular Gas in the Central Region of Lenticular Galaxy PGC 39535

open access: yesThe Astrophysical Journal
Lenticular galaxies (S0s) in the local Universe are generally absent of recent star formation and lack molecular gas. In this paper, we investigate one massive ( M _* ∼ 5 × 10 ^10 M _⊙ ) star-forming S0, PGC 39535, with the Northern Extended Millimeter ...
