Direct Acceleration: Cosmic and Exoplanet Synergies
David Erskine, Alex Kim, Eric Linder +10
Direct measurement of acceleration is a key scientific goal for both cosmology and exoplanets. For cosmology, the concept of redshift drift (more than 60 years old by the 2020s) co…
Visible-spanning flat supercontinuum for astronomical applications
Aakash Ravi, Matthias Beck, David F. Phillips +4
We demonstrate a broad, flat, visible supercontinuum spectrum that is generated by a dispersion-engineered tapered photonic crystal fiber pumped by a 1 GHz repetition rate turn-key…
Astro-comb calibrator and spectrograph characterization using a turn-key laser frequency comb
Aakash Ravi, David F. Phillips, Matthias Beck +8
Using a turn-key Ti:sapphire femtosecond laser frequency comb, an off-the-shelf supercontinuum device, and Fabry-Perot mode filters, we report the generation of a 16 GHz frequency…
