The effect of the impact of comet Shoemaker Levy‐9 on Jupiter's aurorae [PDF]

, 1995
We present infrared spectra and images of the jovian aurorae taken at wavelengths sensitive to the H-3(+) molecular ion during the period around the impact of Comet Shoemaker Levy-9.

Research Progress of Three‐Terminal Perovskite/Silicon Tandem Solar Cells Based on Back‐Contact Silicon

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Perovskite/silicon tandem solar cells offer efficiencies beyond 30%, yet conventional architectures face trade‐offs between optical performance and current matching. Three‐terminal tandems employing silicon back‐contact bottom cells eliminate the current‐matching constraint while minimizing optical losses, offering superior energy yield under real ...

Retrievals of Protoplanetary Disk Parameters Using Thermochemical Models. I. Disk Gas Mass from Hydrogen Deuteride Spectroscopy

The Astrophysical Journal
We discuss statistical relationships between the mass of protoplanetary disks, the hydrogen deuteride (HD) line flux, and the dust spectral energy distribution (SED) determined using 3000 ProDiMo disk models. The models have 15 free parameters describing

Scanning‐Tip and Confocal Raman Characterization of Gold Nanoparticles as Plasmonic Structures for Molecular Sensing

Journal of Raman Spectroscopy, EarlyView.
We apply a sharp silicon tip, typically used for atomic force microscopy (AFM), as a nanoscale probe, and collect frequency‐shifted photons resulting from Raman scattering within the sharp tip. This approach allows us to map local electromagnetic fields in various plasmonic structures and study field “hotspots” with nanometer spatial resolution ...

The Massive and Distant Clusters of WISE Survey 2: A Stacking Analysis Investigating the Evolution of Star Formation Rates and Stellar Masses in Groups and Clusters

The Astrophysical Journal
The evolution of galaxies depends on their masses and local environments; understanding when and how environmental quenching starts to operate remains a challenge.

Submillimeter and Far-Infrared Polarimetric Observations of Magnetic Fields in Star-Forming Regions

Frontiers in Astronomy and Space Sciences, 2019
Observations of star-forming regions by the current and upcoming generation of submillimeter polarimeters will shed new light on the evolution of magnetic fields over the cloud-to-core size scales involved in the early stages of the star formation ...

Tunable Terahertz Generation in Dispersion‐Engineered ZnTe Waveguides

Laser &Photonics Reviews, EarlyView.
A dispersion‐engineered Zinc Telluride (ZnTe) slab waveguide platform enables tunable and efficient guided‐wave terahertz (THz) generation through modal phase matching. By tailoring the optical and THz modal dispersion, coherent THz emission is achieved across 0.1–3 THz.

The far-infrared/submillimeter properties of galaxies located behind the Bullet cluster* [PDF]

, 2010
The Herschel Lensing Survey (HLS) takes advantage of gravitational lensing by massive galaxy clusters to sample a population of high-redshift galaxies which are too faint to be detected above the confusion limit of current far-infrared/submillimeter ...

Reconfigurable Geometric Phase Matching by Multilayered Nonlinear Thin‐Film Crystals

Laser &Photonics Reviews, EarlyView.
The concept of geometric phase matching is demonstrated as a dynamically reconfigurable approach for tunable nonlinear wave mixing in multilayered nonlinear thin‐film crystals. Experimental results reveal full modulation in a bilayer structure and near‐perfect spin‐selective phase matching of second‐harmonic generation in an eight‐layer configuration ...

A balloon-borne 1 meter telescope for far-infrared astronomy [PDF]

, 1974
The flight of a balloon-borne one-meter telescope for infrared astronomy in the wavelength interval of 40 to 240 microns is discussed. The gyro-stabilized telescope mapped the intensity of the far infrared radiation from NGC 7538, Mars, the Orion Nebula,
