We study the method of Voigt profile fitting for ultra-narrow linewidth measurement. It filters
out the effect of the spectrum broadening due to the 1/f frequency noise and extracts out the …

Rotating detonation engines (RDEs) require advanced rapid combustion diagnostic
techniques to better understand their complex detonation processes. A fast mid-infrared …

Accurate discrimination of Shigella spp. sits in the core of shigellosis prevention and control.
As a label-free method, surface enhanced Raman spectroscopy (SERS) is being intensively …

Why did I feel the need to write this book in the first place? I started in astrophysics studying
supernova remnants for my doctoral thesis. Almost immediately after obtaining my doctorate …

Warm Neptunes offer a rich opportunity for understanding exo-atmospheric chemistry. With
the upcoming James Webb Space Telescope (JWST), there is a need to elucidate the …

Motivated by both ground-and space-based detections of the sodium doublet in the
transmission spectra of exoplanetary atmospheres, we revisit the theory and interpretation of …

We provide a remedy for a recently published formulation of the Voigt function by
reformulating the function into a single proper integral with a damped sine integrand. The …

ITER plans foresee the quantitative diagnostics of fuel retention in reactor walls at near-
atmospheric pressures. Using laser induced breakdown spectroscopy (LIBS) for this …

An exact calculation of the Voigt spectral line profile in spectroscopy has been derived using
the Fourier transform method. The analytical formula we calculated is a real function, rather …

We show that the entire x-ray Thomson scattering (XRTS) spectrum, including both elastic
and inelastic features, can be calculated from first principles in the framework of quantum …
