SPECTRAL LINE IDENTIFICATION OF A PHOTOIONIZED SILICON PLASMA IN EMISSION.
2021 IEEE International Conference on Plasma Science (ICOPS), 2021 Photoionized silicon plasma experiments were performed using the Z machine at Sandia National Laboratories. A spectrometer with high spectral resolution (λ/δλ~9200) was conceived to record emission from the expanding plasma. The data resolution is unprecedented for plasma emission and include detections of many previously unobserved spectral lines. The

Line identification in the Ca II K spectral region of sharp-lined B-type stars [PDF]
Astronomy & Astrophysics, 2001 Previous Ca ii K observations of the B-type star HD 83206 have revealed putative high-velocity interstellar clouds (HVCs) at Local Standard of Rest (LSR) velocities of −80 and −110 km s−1. Similar results were also found for the sightline towards HD 135485.

Ultraviolet Line Identifications and Spectral Formation Near Max Light in Type Ia Supernova 2011fe [PDF]
The Astrophysical Journal, 2020 Abstract We present ultraviolet line identifications of near maximum-light Hubble Space Telescope observations of SN 2011fe using synthetic spectra generated from both SYNOW and PHOENIX. We find the spectrum to be dominated by blends of iron group elements Fe, Co, and Ni (as expected due to heavy line blanketing by these elements in the ...

Automated spectral line identification [PDF]
Publications of the Astronomical Society of the Pacific, 1990 Software has been developed to automate the intricate and tedious process of stellar line identification. A set of unknown stellar wavelengths and intensities is compared with a master multiplet list composed of the Revised Multiplet Table plus extensions.

A Graph-Based Method for Molecular Spectral Line Identification
Intelligent ComputingTo address the high computational cost associated with molecular identification in spectral lines, we propose a graph-based feature learning framework to determine the molecular composition of spectral lines that incorporates rule-driven and node-level ...

Saliva as a first-line diagnostic tool: A spectral challenge for identification of cancer biomarkers [PDF]
Journal of Molecular Liquids, 2020 Abstract The paper concentrates on the role of saliva in the early diagnosis of salivary gland tumor. Due to the still not fully understood etiology of head and neck cancer, the fundamental objective of this study is to find tumor markers of salivary gland tumor progression.

Spectral line identification from a photoionised silicon plasma in emission [PDF]
Journal of Plasma PhysicsNext-generation X-ray satellite telescopes such as XRISM, NewAthena and Lynx will enable observations of exotic astrophysical sources at unprecedented spectral and spatial resolution. Proper interpretation of these data demands that the accuracy of the models is at least within the uncertainty of the observations.
