Photonic lantern behaviour and implications for instrument design
Anthony Horton, Robert Content, Simon Ellis +1
Photonic lanterns are an important enabling technology for astrophotonics with a wide range of potential applications including fibre Bragg grating OH suppression, integrated photo…
GAMA: towards a physical understanding of galaxy formation
Simon P. Driver, Peder Norberg, Ivan K. Baldry +46
The Galaxy And Mass Assembly (GAMA) project is the latest in a tradition of large galaxy redshift surveys, and is now underway on the 3.9m Anglo-Australian Telescope at Siding Spri…
Potential of commercial SiN MPW platforms for developing mid/high-resolution integrated photonic spectrographs for astronomy
Pradip Gatkine, Nemanja Jovanovic, Christopher Hopgood +6
Integrated photonic spectrographs offer an avenue to extreme miniaturization of astronomical instruments, which would greatly benefit extremely large telescopes and future space mi…
Seeking celestial Positronium with an OH-suppressed diffraction-limited spectrograph
J. Gordon Robertson, Simon Ellis, Qingshan Yu +4
Celestially, Positronium (Ps), has only been observed through gamma-ray emission produced by its annihilation. However, in its triplet state, a Ps atom has a mean lifetime long eno…
The GALAH survey and Gaia DR2: dissecting the stellar disc's phase space by age, action, chemistry and location
Joss Bland-Hawthorn, Sanjib Sharma, Thor Tepper-Garcia +24
We use the second data releases of the ESA Gaia astrometric survey and the high-resolution GALAH spectroscopic survey to analyse the structure of our Galaxy's disc components. With…
The Sydney-AAO Multi-object Integral field spectrograph (SAMI)
Scott M. Croom, Jon S. Lawrence, Joss Bland-Hawthorn +22
We demonstrate a novel technology that combines the power of the multi-object spectrograph with the spatial multiplex advantage of an integral field spectrograph (IFS). The Sydney-…
2023 Astrophotonics Roadmap: pathways to realizing multi-functional integrated astrophotonic instruments
Nemanja Jovanovic, Pradip Gatkine, Narsireddy Anugu +77
Photonics offer numerous functionalities that can be used to realize astrophotonic instruments. The most spectacular example to date is the ESO Gravity instrument at the Very Large…
Astro2020: Astrophotonics White Paper
Pradip Gatkine, Sylvain Veilleux, John Mather +19
Astrophotonics is the application of versatile photonic technologies to channel, manipulate, and disperse guided light from one or more telescopes to achieve scientific objectives…
Multicore fibre technology - the road to multimode photonics
Joss Bland-Hawthorn, Seong-Sik Min, Emma Lindley +6
For the past forty years, optical fibres have found widespread use in ground-based and space-based instruments. In most applications, these fibres are used in conjunction with conv…
PRAXIS: low thermal emission high efficiency OH suppressed fibre spectrograph
Robert Content, Joss Bland-Hawthorn, Simon Ellis +12
PRAXIS is a second generation instrument that follows on from GNOSIS, which was the first instrument using fibre Bragg gratings for OH background suppression. The Bragg gratings re…
PRAXIS: a low background NIR spectrograph for fibre Bragg grating OH suppression
Anthony Horton, Simon Ellis, Jon Lawrence +1
Fibre Bragg grating (FBG) OH suppression is capable of greatly reducing the bright sky background seen by near infrared spectrographs. By filtering out the airglow emission lines a…
