Mapping the aberrations of a wide-field spectrograph using a photonic comb
Joss Bland-Hawthorn, Janez Kos, Christopher Betters +4
We demonstrate a new approach to calibrating the spectral-spatial response of a wide-field spectrograph using a fibre etalon comb. Conventional wide-field instruments employed on f…
GNOSIS: the first instrument to use fibre Bragg gratings for OH suppression
Christopher Q. Trinh, Simon C. Ellis, Joss Bland-Hawthorn +20
GNOSIS is a prototype astrophotonic instrument that utilizes OH suppression fibres consisting of fibre Bragg gratings and photonic lanterns to suppress the 103 brightest atmospheri…
Design of Optically Path Length Matched, Three-Dimensional Photonic Circuits Comprising Uniquely Routed Waveguides
Ned Charles, Nemanja Jovanovic, Simon Gross +6
A method for designing physically path length matched, three-dimensional photonic circuits is described. We focus specifically on the case where all the waveguides are uniquely rou…
Age patterns in a sample of nearby spiral galaxies
M. Carmen Sánchez-Gil, D. Heath Jones, Enrique Pérez +3
We present the burst ages for young stellar populations in a sample of six nearby (< 10 Mpc) spiral galaxies using a differential pixel-based analysis of the ionized gas emission.…
The radius and other fundamental parameters of the F9 V star beta Virginis
J. R. North, J. Davis, J. G. Robertson +10
We have used the Sydney University Stellar Interferometer (SUSI) to measure the angular diameter of the F9 V star beta Virginis. After correcting for limb darkening and combining w…
A new determination of the orbit and masses of the Be binary system delta Scorpii
W. J. Tango, J. Davis, A. P. Jacob +5
The binary star delta Sco (HD143275) underwent remarkable brightening in the visible in 2000, and continues to be irregularly variable. The system was observed with the Sydney Univ…
