  • Calibration of an echelle spectrograph with an astro-comb: a laser frequency comb with very high repetition rate 
    Phillips, David F.; Glenday, Alex; Li, Chih-Hao; Furesz, Gabor; Benedick, Andrew J.; Chang, Guoqing N.; Chen, Li-Jin; Korzennik, Sylvain; Sasselov, Dimitar; Kaertner, Franz X.; Szentgyorgyi, Andrew H.; Walsworth, Ronald L. (2012)
    Searches for extrasolar planets using precision radial velocity (PRV) techniques are approaching Earth-like planet sensitivity, however require an improvement of one order of magnitude to identify earth-mass planets in the ...
  • Green astro-comb for HARPS-N 
    Li, Chih-Hao; Glenday, Alexander G.; Phillips, David F.; Furesz, Gabor; Langellier, Nicholas; Webber, Matthew; Zibrov, Alexander; Benedick, Andrew J.; Chang, Guoqing; Chen, Li-Jin; Sasselov, Dimitar; Kärtner, Franz; Szentgyorgyi, Andrew H.; Walsworth, Ronald L. (2012)
    Searches for Earth-like exoplanets using the stellar radial velocity measurements require accuracy <SUP>-10</SUP> in the visible spectral range. We have developed a green astro-comb that generates ~6000 lines equally spaced ...
  • High-resolution Fourier transform spectrograph for characterization of echelle spectrograph wavelength calibrators 
    Glenday, Alexander G.; Phillips, David F.; Webber, Matthew; Li, Chih-Hao; Furesz, Gabor; Chang, Guoqing; Chen, Li-Jin; Kärtner, Franz X.; Sasselov, Dimitar D.; Szentgyorgyi, Andrew H.; Walsworth, Ronald L. (2012)
    Wavelength calibrators are a critical component of high precision and accuracy radial velocity measurements. An order of magnitude improvement of the state-of-the-art of calibration of echelle spectrographs is amongst the ...
