A broadband thermal emission spectrum of the ultra-hot Jupiter WASP-18b. [PDF]

open access: yesNature, 2023
The dayside thermal emission spectrum and brightness temperature map of the ultra-hot Jupiter WASP-18b obtained from the NIRISS instrument on the JWST showed water emission features, an atmosphere consistent with solar metallicity, as well as a steep and

Emission spectrum of quasi-resonant laterally coupled quantum dots [PDF]

open access: yes, 2011
We calculate the emission spectrum of neutral and charged excitons in a pair of laterally coupled InGaAs quantum dots with nearly degenerate energy levels.

Measurement of the emission spectrum of a semiconductor laser using laser-feedback interferometry. [PDF]

open access: yesSci Rep, 2017
The effects of optical feedback (OF) in lasers have been observed since the early days of laser development. While OF can result in undesirable and unpredictable operation in laser systems, it can also cause measurable perturbations to the operating ...

Time parameters of optimal emission spectrum registration using millisecond laser pulses [PDF]

open access: yesРадиофизика и электроника, 2020
Subject and Purpose. Emission spectra of copper-silver alloys are examined for various recording durations. The radiation coming to the photodetector of the spectrometer consists of the reflected laser radiation and the line spectra of vapors formed by ...

Metabolomics of Pseudomonas aeruginosa Treated by Atmospheric-Pressure Cold Plasma

open access: yesApplied Sciences, 2021
With increasing drug resistance of Pseudomonas aeruginosa, a new sterilization method is needed. Plasma has been shown to be an effective method of sterilization, but no researchers have studied the effect of plasma on bacterial metabolism. In this paper,

The Electron Spectrum in 3C 279 and the Observed Emission Spectrum [PDF]

open access: yesThe Astrophysical Journal, 2003
The emission mechanisms of the blazar 3C 279 are studied by solving the kinetic equations of electrons and photons in a relativistically moving blob. The gamma-ray spectral energy distribution (SED) is fitted by inverse Compton scattering of external photons.
