Asteroid Polarimetric-Phase Behavior in the Near-Infrared: S- and C-Complex Objects [PDF]
arXiv, 2022 We present the first results of our survey of asteroid polarization-phase curves in the near-infrared J and H bands using the WIRC+Pol instrument on the Palomar 200-inch telescope. We confirm through observations of standard stars that WIRC+Pol can reach the 0.1% precision needed for asteroid phase curve characterization, and show that C-complex ...

Near infrared spectroscopy for fibre based gas detection [PDF]
, 2010 Gas sensing systems based on fibre optic linked near infra red absorption cells are potentially a flexible and effective tool for monitoring accumulations of hazardous and noxious gases in enclosed areas such as tunnels and mines.

Modelling of integrated-light spectra from the optical to the near-infrared: the globular cluster G280 in M31 [PDF]
A&A 617, A119 (2018), 2018 In previous papers, we introduced our method for measuring chemical abundances from integrated-light spectra of globular clusters and applied it to a variety of extragalactic star clusters. Here we extend our analysis technique to the infrared. We simultaneously analyse an optical spectrum of the massive globular cluster G280 in M31, obtained with the ...

Extending the Canada-France brown Dwarfs Survey to the near-infrared: first ultracool brown dwarfs from CFBDSIR [PDF]
, 2010 We present the first results of the ongoing Canada-France Brown Dwarfs Survey-InfraRed, hereafter CFBDSIR, a Near InfraRed extension to the optical wide-field survey CFBDS. Our final objectives are to constrain ultracool atmosphere physics by finding a statistically significant sample of objects cooler than 650K and to explore the ultracool brown dwarf

Telluric correction in the near-infrared: Standard star or synthetic transmission? [PDF]
A&A 621, A79 (2019), 2018 Context. The atmospheric absorption of the Earth is an important limiting factor for ground-based spectroscopic observations and the near-infrared and infrared regions are the most affected. Several software packages that produce a synthetic atmospheric transmission spectrum have been developed to correct for the telluric absorption; these are Molecfit,

Understanding near infrared spectroscopy and its application to skeletal muscle research.
Journal of applied physiology, 2019 Near infrared spectroscopy (NIRS) is a powerful noninvasive tool with which to study the matching of oxygen delivery to oxygen utilization and the number of new publications utilizing this technique has increased exponentially in the last 20 yr.

Early-type galaxies in the near-infrared: 1.5-2.4\mum spectroscopy [PDF]
, 2008 Near-infrared (hereafter NIR) data may provide complementary information to the traditional optical population synthesis analysis of unresolved stellar populations because the spectral energy distribution of the galaxies in the 1-2.5\mum range is dominated by different types of stars than at optical wavelengths.

AKARI Near-Infrared Spectroscopy of Luminous Infrared Galaxies
, 2012 We present the AKARI near-infrared (NIR; 2.5-5 micron) spectroscopic study of 36 (ultra)luminous infrared galaxies [(U)LIRGs] at z=0.01-0.4. We measure the NIR spectral features including the strengths of 3.3 micron polycyclic aromatic hydrocarbon (PAH ...
