Performance of AAOmega: the AAT multi-purpose fiber-fed spectrograph

Abstract: AAOmega is the new spectrograph for the 2dF fibre-positioning system on the Anglo-Australian Telescope. It is a bench-mounted, double-beamed design, using volume phase holographic (VPH) gratings and articulating cameras. It is fed by 392 fibres from either of the two 2dF field plates, or by the 512 fibre SPIRAL integral field unit (IFU) at Cassegrain focus. Wavelength coverage is 370 to 950nm and spectral resolution 1,000-8,000 in multi-Object mode, or 1,500-10,000 in IFU mode. Multi-object mode was commission… Show more

“…This has a direct influence on our ability to carry out precise sky subtraction (Sharp, Brough & Cannon 2013). To examine the throughput estimates we measure the rms scatter in throughput over the typical 7 × 1800 s exposures taken for each field.…”

“…SAMI makes use of hexabundles, bundles of 61 fibres that are fused together and have a high optical performance and ∼75 per cent filling factor Bryant et al 2011Bryant et al , 2014a. The fibres feed into the existing AAOmega spectrograph (Sharp et al 2006), a double-beamed spectrograph that offers a range of configurations suitable for galaxy spectroscopy. Since its commissioning in 2012, SAMI observations have been used for studies of galactic winds (Fogarty et al 2012; Ho et al 2014), the kinematic morphology-density relation (Fogarty et al 2014) and star formation in dwarf galaxies (Richards et al 2014).…”

“…Silk & Mamon 2012), and are clearly detected by combining gaseous emissionline ionisation diagnostics with kinematics (e.g. Sharp & Bland-Hawthorn 2010;Fogarty et al 2012;Ho et al 2014Ho et al , 2016a. Gas inflows can be traced using the measurement of misalignment between gas and stellar kinematics (e.g.…”

“…The 13 IFUs and 26 sky fibres are inserted into pre-drilled plates using magnetic connectors. Optical fibres from SAMI feed into AAOmega, a bench-mounted double-beam optical spectrograph (Sharp et al 2006). AAOmega provides a selection of different spectral resolutions and wavelength ranges.…”

“…We observed XMMSL1 J0619-65 with the AAOmega 2dF spectrograph (Saunders et al 2004;Sharp et al 2006) at the prime focus of the Anglo-Australian Telescope on 2012-12-03 for 3 ×600 s, in order to obtain an optical classification of the source and to search for transient emission lines excited by the flare. We used the 580V (3700−5800 A) and 385R (5600−8800 A) low-resolution gratings (R 1300).…”
