Single mode, extreme precision Doppler spectrographs
Christian Schwab, Sergio G. Leon-Saval, Christopher H. Betters +2
The 'holy grail' of exoplanet research today is the detection of an earth-like planet: a rocky planet in the habitable zone around a main-sequence star. Extremely precise Doppler s…
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…
First Science with SAMI: A Serendipitously Discovered Galactic Wind in ESO 185-G031
Lisa M. R. Fogarty, Joss Bland-Hawthorn, Scott M. Croom +27
We present the first scientific results from the Sydney-AAO Multi-Object IFS (SAMI) at the Anglo-Australian Telescope. This unique instrument deploys 13 fused fibre bundles (hexabu…
Kinematics of the stellar halo and the mass distribution of the Milky Way using BHB stars
Prajwal R. Kafle, Sanjib Sharma, Geraint F. Lewis +1
Here we present a kinematic study of the Galactic halo out to a radius of 60 kpc, using 4664 blue horizontal branch (BHB) stars selected from the SDSS/SEGUE survey, to deter…
Thin disk kinematics from RAVE and the solar motion
S. Pasetto, E. K. Grebel, T. Zwitter +14
Aims. We study the Milky Way thin disk with the Radial Velocity Experiment (RAVE) survey. We consider the thin and thick disks as different Galactic components and present a techni…
Thick disk kinematics from RAVE and the solar motion
S. Pasetto, E. K. Grebel, T. Zwitter +14
Radial velocity surveys such as the Radial Velocity Experiment (RAVE) provide us with measurements of hundreds of thousands of nearby stars most of which belong to the Galactic thi…
