M67 Blue Stragglers with High-resolution Infrared Spectroscopy
The Astronomical Journal, 2023 We report on the first detailed infrared chemical analysis of five binary members (S277, S997, S975, S1031, and S1195) in the open cluster M67 (NGC 2682).

Finding extraterrestrial life using ground-based high-resolution spectroscopy [PDF]
, 2013 Exoplanet observations promise one day to unveil the presence of extraterrestrial life. Atmospheric compounds in strong chemical disequilibrium would point to large-scale biological activity just as oxygen and methane do in the Earth's atmosphere.

Fast High Resolution Echelle Spectroscopy Of A Laboratory Plasma [PDF]
, 2006 An echelle diffraction grating and a multianode photomultiplier tube are paired to construct a high resolution (R=lambda/delta lambda approximate to 2.5x10(4)) spectrograph with fast time response for use from the UV through the visible.

Fundamental constants and high‐resolution spectroscopy [PDF]
Astronomische Nachrichten, 2014 AbstractAbsorption‐line systems detected in high resolution quasar spectra can be used to compare the value of dimensionless fundamental constants such as the fine‐structure constant, α, and the proton‐to‐electron mass ratio, μ = mp/me, as measured in remote regions of the Universe to their value today on Earth.

Chandra High Resolution X-ray Spectroscopy of AM Her [PDF]
, 2007 We present the results of high resolution spectroscopy of the prototype polar AM Herculis observed with Chandra High Energy Transmission Grating. The X-ray spectrum contains hydrogen-like and helium-like lines of Fe, S, Si, Mg, Ne and O with several Fe L-

High-Resolution Photoelectron Spectroscopy of Molecules [PDF]
, 1995 Rotationally resolved photoelectron spectra can provide significant insight into the underlying dynamics of molecular photoionization. Here, we discuss and compare results of recent theoretical studies of rotationally resolved photoelectron spectra ...

Mid-infrared dual-comb spectroscopy with an optical parametric oscillator [PDF]
, 2013 We present the first implementation of mid-infrared dual-comb spectroscopy with an optical parametric oscillator. Methane absorption spectroscopy was demonstrated with a resolution of 0.2 cm(-1) (5 GHz) at an acquisition time of similar to 10.4 ms over a

ExoGemS Detection of a Metal Hydride in an Exoplanet Atmosphere at High Spectral Resolution
The Astrophysical Journal Letters, 2023 Exoplanet atmosphere studies are often enriched by synergies with brown dwarf analogs. However, many key molecules commonly seen in brown dwarfs have yet to be confirmed in exoplanet atmospheres.
