How Massive Star Clusters Form and Evolve: A Near-IR Survey of the W51 Complex
We present near-infrared JHK _s and narrowband H _2 (1–0) photometric observations of the W51A region, obtained with GTC EMIR, aiming to characterize its young stellar population, and provide mass estimates for individual cluster members and the ...

Surface plasmon enhanced infrared photodetection
infrared photodetectors have been used extensively in biomedicine, surveillance, communication and astronomy. however, state of the art technology based on Ⅲ-Ⅴ and Ⅱ-Ⅵ compounds still lacks excellent performance for high-temperature operation.

An Improved Atlas of Full-scan Spectra from ISO/SWS
We present an atlas of full-scan spectra from the Short-Wavelength Spectrometer (SWS) on board the Infrared Space Observatory after reprocessing and improving an earlier version published 22 yr ago. The SWS spectra cover the wavelength range from 2.35 to

A Simple Model of the Radio–Infrared Correlation Depending on Gas Surface Density and Redshift
We introduce a simple parametric model of the radio–infrared correlation (i.e., the ratio between the IR luminosity and the 1.4 GHz radio luminosity, q _IR ) by considering the energy loss rate of high-energy cosmic-ray (CR) electrons governed by ...

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