Generative AI-Enabled Discovery and Experimental Demonstration of Ultra-Broadband Epsilon-Near-Zero Perfect Absorbers. [PDF]

Adv Sci (Weinh)
Researchers developed and applied a generative artificial intelligence (AI) model to optimize epsilon‐near‐zero thin film stacks for ultra‐broadband perfect absorption of light. The fabricated AI‐designed absorber, with a total thickness of only 160 nm, experimentally demonstrated an absorption bandwidth exceeding 1000 nm while maintaining greater than

Wide-field dynamic astronomy in the near-infrared with Palomar Gattini-IR and DREAMS [PDF]

Advances in Optical Astronomical Instrumentation 2019, 2020
There have been a dramatic increase in the number of optical and radio transient surveys due to astronomical transients such as gravitational waves and gamma ray bursts, however, there have been a limited number of wide-field infrared surveys due to narrow field-of-view and high cost of infrared cameras, we present two new wide-field near-infrared ...

Integration of a Testbench for the Optical and Thermal Characterization of Near-Infrared Detectors Used in Ground and Space-Based Astronomy [PDF]

IEEE Transactions on Instrumentation and Measurement, 2021
The mercury–cadmium–tellurium (MCT) sensors are considered the ideal infrared detectors to equip the focal plane arrays (FPAs) of astronomical scientific missions. To tackle Europe to be self-sufficient on this technology and promote to reach the same maturity level attained by the current MCT sensors market leaders, the Astronomy European Infrared ...

Validation of the near infrared spectroscopy method for determining soil organic carbon by employing a proficiency assay for fertility laboratories [PDF]

, 2021
Current research indicates that near infrared (NIR) spectroscopy is the most promising alternative technique for the determination of soil organic carbon (SOC) in laboratories worldwide and that it may serve as a total or partial replacement for the ...

Toward Measuring the Microlensing Event Rate in the Galactic Center. I. Event Detection from the UKIRT Microlensing Survey Data

The Astrophysical Journal Supplement Series, 2023
To overcome the high optical extinction, near-infrared (NIR) observations are needed for probing the microlensing events toward the Galactic center. The 2015–2019 UKIRT microlensing survey toward the Galactic center is the first dedicated precursor NIR ...

Background-limited Imaging in the Near Infrared with Warm InGaAs Sensors: Applications for Time-domain Astronomy [PDF]

The Astronomical Journal, 2019
Abstract We describe test observations made with a customized 640 × 512 pixel indium gallium arsenide (InGaAs) prototype astronomical camera on the 2.5 m DuPont telescope. This is the first test of InGaAs as a cost-effective alternative to HgCdTe for research-grade astronomical observations. The camera exhibits a background of 113 e– s–1/
