Selection of ThAr lines for wavelength calibration of echelle spectra and implications for variations in the fine-structure constant
M. T. Murphy, P. Tzanavaris, J. K. Webb +1
Echelle spectrographs currently provide some of the most precise and detailed spectra in astronomy, the interpretation of which sometimes depends on the wavelength calibration accu…

High-precision wavelength calibration of astronomical spectrographs with laser frequency combs
M. T. Murphy, Th. Udem, R. Holzwarth +8
We describe a possible new technique for precise wavelength calibration of high-resolution astronomical spectrographs using femtosecond-pulsed mode-locked lasers controlled by stab…

H-alpha kinematics of a z ~ 1 disc galaxy from near-IR integral field spectroscopy
J. K. Smith, A. J. Bunker, N. P. Vogt +6
In this letter we present the first 3D spectroscopic study of H-alpha emission in a z ~ 1 field galaxy with an integral field unit. Using the CIRPASS spectrograph on Gemini-South w…
