Mapping the dynamics, star-formation rates, and chemical properties of galaxies with integral field spectroscopy [PDF]

, 2005
Major advances in the development of instruments for eight and ten meter class telescopes are revolutionising our understanding of galaxy formation. In particular, Integral Field Spectrographs (which produce a three dimensional {x, y, velocity) map of a ...

Geology of the Selk crater region on Titan from Cassini VIMS observations

, 2010
International audienceObservations of Titan obtained by the Cassini Visual and Infrared Mapping Spectrometer (VIMS) have revealed Selk crater, a geologically young, bright-rimmed, impact crater located similar to 800 km north-northwest of the Huygens ...

Memristive Physical Reservoir Computing

Advanced Science, Volume 13, Issue 33, 15 June 2026.
Memristors’ nonlinear dynamics and input‐dependent memory effects make them ideal candidates for high‐performance physical reservoir computing (RC). Based on their conductance modulation, memristors can be classified as electronic or optoelectronic types.

Design and Simulation of TiN-Based Suspended Meander Kinetic Inductance Detectors (KIDs) for Visible and Near-Infrared Astronomy Applications

Journal of Low Temperature Physics
We report on simulations of a novel design of optical titanium nitride (TiN)- based Kinetic Inductance Detectors (KIDs) in order to improve their response to optical photons. We propose to separate the meander from the substrate to trap hot phonons generated by optical photons, preventing their rapid propagation through the substrate.

Uranium Doped Gallium Nitride Epitaxial Thin Films

Advanced Electronic Materials, Volume 12, Issue 12, 22 June 2026.
Uranium was controllably added to gallium nitride using molecular beam epitaxy. The uranium atoms segregated into vertically oriented regions with higher doping levels. Concentrations up to a few percent were achieved without showing significant degradation in the crystalline quality or optical characteristics. Low electrical resistivity was maintained

Near-infrared evolution of the equatorial ring of SN 1987A [PDF]

We used adaptive optics imaging and integral field spectroscopy from the Very Large Telescope, together with images from the Hubble Space Telescope, to study the near-infrared (NIR) evolution of the equatorial ring (ER) of SN 1987A.

Astro2020 Activity, Project of State of the Profession Consideration (APC) White Paper: All-Sky Near Infrared Space Astrometry. State of the Profession Considerations: Development of Scanning NIR Detectors for Astronomy

, 2019
Gaia is a revolutionary space mission developed by ESA and is delivering 5 parameter astrometry, photometry and radial velocities over the whole sky with astrometric accuracies down to a few tens of micro-arcseconds. A weakness of Gaia is that it only operates at optical wavelengths.

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

Advanced Electronic Materials, Volume 12, Issue 12, 22 June 2026.
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 ...
