Cometary Delivery of Hydrogen Cyanide to the Early Earth

Journal Article
Delivery of water and organics by asteroid and comet impacts may have influenced prebiotic chemistry on the early Earth. Some recent prebiotic chemistry experiments emphasize hydrogen cyanide (HCN) as a feedstock molecule for the formation of sugars...

Visible-Spanning Flat Supercontinuum for Astronomical Applications

Journal Article

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 Ti:sapphire laser outputting ~30 fs pulses at 800 nm. At a pulse energy...
