Gravitational wave (GW) astronomy has entered a new era with the direct detection of dekahertz-band GW signals by laser interferometers. As with the electromagnetic spectrum, observing gravitational waves in a range of different frequency bands will yield complementary insights into the astrophysics of gravitating objects. Gravitational waves at micro-hertz to milli-hertz frequencies can be...

We will discuss recent spectroscopic results for He-broadened transitions of carbon monoxide in the fundamental band, performed over a range of temperatures from 80 to 296 K. Experimentally, the spectral line parameters and their temperature dependencies were retrieved using a multispectrum analysis software and different line shape models (Voigt, speed dependent Voigt, Rautian, Rautian with...

We have re-analyzed room-temperature spectra of first overtone band of CO and CO broadened by hydrogen. We have employed the Voigt, speed depended Voigt, Rautian, and Rautian with speed dependence line shape models and a multispectrum fit software [1].
The line mixing coefficients have been calculated using scaling laws. The CO line widths in CO-Hydrogen and CO-CO collisions were calculated...

This paper is part of a joint theoretical/experimental project to test QED by measuring the tune-out wavelength of helium near the 413 nm line where the frequency-dependent polarizability vanishes [1]. As a first strep, we calculate a high-precision value for the static polarizability defined in the nonrelativistic limit as the second-order perturbation energy due to the perturbation...

The infrared Fourier transform spectrum of the asymmetric C-H stretching bands of CH$_{3}$SH has been recorded in the 2950-3100 cm$^{-1}$ region using synchrotron radiation at the FIR beamline of the Canadian Light Source in Saskatoon. Assignment of numerous torsion-rotation sub-bands for the asymmetric stretches has revealed a surprising pseudo-symmetric behavior, in which each band is seen...
