High-resolution spectroscopy of buffer-gas-cooled phthalocyanine [PDF]

open access: yesCommunications Chemistry, 2022
High-resolution molecular spectroscopy provides invaluable insight into the quantum properties of molecules, but high-resolution rovibronic spectroscopy has largely been limited to relatively small systems owing to the difficulty in preparing ...

High-Resolution Nanoscale Solid-State Nuclear Magnetic Resonance Spectroscopy

open access: yesPhysical Review X, 2018
We present a new method for high-resolution nanoscale magnetic resonance imaging (nano-MRI) that combines the high spin sensitivity of nanowire-based magnetic resonance detection with high-spectral-resolution nuclear magnetic resonance (NMR) spectroscopy.

Instrumentation prospects for rocky exoplanet atmospheres studies with high resolution spectroscopy [PDF]

open access: yesScientific Reports
Studying the atmospheres of exoplanets is one of the most promising ways to learn about distant worlds beyond our solar system. The composition of an exoplanet’s atmosphere can provide critical insights into its geology and potential habitability.

Spatial spectroscopy for high resolution imaging [PDF]

open access: yesEPJ Web of Conferences, 2020
Quantum estimation theory provides bounds for the precision in the estimation of a set of parameters that characterize a system. Two questions naturally arise: Is any of these bounds tight?

Shock Excitation in Narrow-line Regions Powered by AGN Outflows

open access: yesThe Astrophysical Journal, 2023
Outflows in an active galactic nucleus (AGN) are considered to play a key role in the evolution of the host galaxy through transfer of a large amount of energy.

Metallicities of Classical Cepheids in the Inner Galactic Disk

open access: yesThe Astrophysical Journal, 2023
Metallicity gradients refer to the sloped radial profiles of the metallicities of gas and stars and are commonly seen in disk galaxies. A well-defined metallicity gradient of the Galactic disk is observed particularly well with classical Cepheids, which ...

High-resolution ultrasonic spectroscopy [PDF]

open access: yesJournal of Sensors and Sensor Systems, 2018
High-resolution ultrasonic spectroscopy (HR-US) is an analytical technique for direct and non-destructive monitoring of molecular and micro-structural transformations in liquids and semi-solid materials.

Acyl-Lipid Δ6-Desaturase May Act as a First FAD in Cyanobacteria

open access: yesBiomolecules, 2022
Fatty acid desaturases (FADs) play important roles in various metabolic and adaptive pathways in all living organisms. They represent a superfamily of oxygenases that introduce double bonds into the acyl chains of fatty acids (FAs).
