Suppression of the near-infrared OH night sky lines with fibre Bragg gratings - first results
S. C. Ellis, J. Bland-Hawthorn, J. Lawrence +20
The background noise between 1 and 1.8 microns in ground-based instruments is dominated by atmospheric emission from hydroxyl molecules. We have built and commissioned a new instru…

A complex multi-notch astronomical filter to suppress the bright infrared sky
J. Bland-Hawthorn, S. C. Ellis, S. G. Leon-Saval +10
A long-standing and profound problem in astronomy is the difficulty in obtaining deep near-infrared observations due to the extreme brightness and variability of the night sky at t…

Characterization and on-sky demonstration of an integrated photonic spectrograph for astronomy
N. Cvetojevic, J. S. Lawrence, S. C. Ellis +3
We present results from the first on-sky demonstration of a prototype astronomical integrated photonic spectrograph (IPS) using the Anglo-Australian Telescope near-infrared imaging…
