🌌 OPEN NIGHT AT THE NRF-SAAO
Join us for an evening of astronomy, science and exploration at the NRF-SAAO in Cape Town.
This month’s 2nd Open Night presentation will be delivered by:
🎤 *Malcolm Scarrott*
Presenting:
✨ *“Commissioning and Qualifying a Titanium Sapphire-Based Laser Frequency Comb for Precision Radial Velocity Measurements with SALT’s High Resolution Spectrograph”*
How can tiny movements in distant stars reveal the presence of planets orbiting them?
Malcolm will explore the science behind the search for exoplanets and explain how Laser Frequency Combs provide the extremely precise calibration needed to measure subtle changes in a star’s motion.
He will introduce the Laser Frequency Comb being developed for the Southern African Large Telescope’s High Resolution Spectrograph, discuss improvements made to the instrument during 2026 and share results from testing its performance in the laboratory and on the sky.
Malcolm is a Master’s student at the University of Cape Town with a passion for astronomical instrumentation and precision radial velocity research.
Following the presentation, guests can enjoy a guided tour of the Observatory and, weather permitting, stargazing through our outreach telescopes.
