  title = {Frequency Comb Velocity-Modulation Spectroscopy},
  abstract = {We have demonstrated a new technique that provides massively parallel comb spectroscopy sensitive specifically to ions through the combination of cavity-enhanced direct frequency comb spectroscopy with velocity-modulation spectroscopy. Using this novel system, we have measured electronic transitions of HfF+ and achieved a fractional absorption sensitivity of 3×10-7 recorded over 1500 simultaneous channels spanning 150  cm-1 around 800 nm with an absolute frequency accuracy of 30 MHz (0.001  cm-1). A fully sampled spectrum consisting of interleaved measurements is acquired in 30 min.},
