High-resolution isotope-shift spectroscopy of Cd i

Physical Review Research, 2023
We present absolute frequency measurements of the ^{1}P_{1}←^{1}S_{0} (229-nm) and ^{3}P_{1}←^{1}S_{0} (326-nm) transitions for all naturally occurring isotopes of cadmium.

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.

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.

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.

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.

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-

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
