Design and development of an adaptive optics system in visible and near-infrared for Inter-University Centre for Astronomy and Astrophysics 2-meter telescope [PDF]

Journal of Astronomical Telescopes, Instruments, and Systems, 2019
Robo-AO is the first robotic autonomous laser-guided adaptive optics (AO) system operating in the sky. It is a very economical AO system especially suitable for observations with 1- to 3-m class telescopes. A second Robo-AO system, which works both in the visible and near-infrared wavelengths, has been developed to improve the image quality of the 2-m ...

Cerebral near-infrared spectroscopy guided neonatal intensive care management for the preterm infant [PDF]

Infants requiring admission to the neonatal intensive care unit (NICU) are particularly vulnerable to developing brain injury. The severity of the underlying clinical conditions and the complexity of care call for continuous, cot-side, non-invasive ...

NEOWISE Data Processing and Color Corrections for Near-Earth Asteroid Observations

The Planetary Science Journal
The Wide-field Infrared Survey Explorer and NEOWISE missions are a key source of thermal data for near-Earth asteroids (NEAs). These missions, which utilized a space-based platform in Earth orbit, produced thermal images across four different wavelength ...

Covalently Locked Donor–Acceptor Block Copolymer Nanoparticles Enable Efficient, Stable and Reproducible Photocatalytic Hydrogen Evolution

Advanced Energy Materials, EarlyView.
To overcome the efficiency–stability trade‐off of traditional donor:acceptor blends, covalently locked all‐conjugated block copolymer nanoparticles are developed for solar hydrogen production. This strategy achieves an outstanding HER rate exceeding 120 mmol cm−2 g−1 h−1, alongside exceptional operational stability (95% retention after 96 h) and high ...

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

, 2023
Abstract We propose high-Q factors sub-stoichiometric TiN-based Lumped Element MKIDs on sapphire with vacuum gap suspended meander. The aim is to improve detector response by trapping phonons within the meander to increase the number of Cooper pairs breaking into quasiparticles.

Grain Size Effects on UV-MIR Spectra of Aubrites: Clues for Interpreting E-type Near-Earth Asteroids

The Planetary Science Journal
The Vera C. Rubin Observatory and the future NEO Surveyor infrared space telescope are expected to dramatically increase the number of near-Earth object discoveries. Among these new objects, we expect small (0.40).
