On-sky commissioning of MAROON-X: A new precision radial velocity spectrograph for Gemini North
A. Seifahrt, J. L. Bean, J. Stürmer +10
MAROON-X is a fiber-fed, red-optical, high precision radial velocity spectrograph recently commissioned at the Gemini North telescope on Mauna Kea, Hawai'i. With a resolving power…
Veloce Rosso: Australia's new precision radial velocity spectrograph
James Gilbert, Christoph Bergmann, Gabe Bloxham +24
Veloce is an ultra-stable fibre-fed R4 echelle spectrograph for the 3.9 m Anglo-Australian Telescope. The first channel to be commissioned, Veloce 'Rosso', utilises multiple low-co…
Development and construction of MAROON-X
Andreas Seifahrt, Jacob L. Bean, Julian Stürmer +4
We report on the development and construction of a new fiber-fed, red-optical, high-precision radial-velocity spectrograph for one of the twin 6.5m Magellan Telescopes in Chile. MA…
First Light Results from the Hermes Spectrograph at the AAT
Andrew Sheinis, Borja Anguiano, Martin Asplund +60
The High Efficiency and Resolution Multi Element Spectrograph, HERMES, is a facility-class optical spectrograph for the Anglo-Australian Telescope (AAT). It is designed primarily f…
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…
CYCLOPS2: the fibre image slicer upgrade for the UCLES high resolution spectrograph
Anthony Horton, C. G. Tinney, Scott Case +10
CYCLOPS2 is an upgrade for the UCLES high resolution spectrograph on the Anglo-Australian Telescope, scheduled for commissioning in semester 2012A. By replacing the 5 mirror Coudé…
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…
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…
