Sydney-AAO Multi-object Integral field spectrograph (SAMI)

  • 13 integral field units (IFUs),each with a field of view of 15arcsec
12 galaxies and 1 secondary star
  • each IFU consists of a bundle of 61 optical fibers a high filling factor ~75%)
  • installed on the 3.9-m Anglo-Australian Telescope (AAT),1 deg FOV
  • 370–570 nm with R=1730 in the blue arm, and 625–735 nm with R = 4500 in the red arm.

SAMI Galaxy survey

  • aim: IFS data for 3400 galaxies
  • Sample:
a field and group sample from GAMA G09, G12 and G15 fields
a cluster sample from a set of eight galaxy clusters.
  • EDR, 107 galaxies [1]

which utilizes pPXF for stellar template fitting and the MPFIT library (MILES templates) for estimating emission-line properties.
