This page provides information for members of the astronomical community interested in specific fields that the SAMI Galaxy Survey has observed or plans to observe soon. We are observing galaxies in from two main samples, carefully matched to allow cross-comparison. The first is selected from the Galaxy And Mass Assembly (GAMA) survey, and the second is from a set of 8 massive galaxy clusters.
Details of the target selection are in Bryant et al. 2014, MNRAS (soon to be submitted).
SAMI targets in the GAMA fields
The main sample of galaxies targeted by SAMI are in areas surveyed by the GAMA project. In particular the GAMA-I G09, G12 and G15 areas which are:
|Field||RA range||Dec range|
|G09||129.0 to 141.0||−1 to +3|
|G12||174.0 to 186.0||−2 to +2|
|G15||211.5 to 223.5||−2 to +2|
The list of object names, GAMA IDs, RA, DEC, redshift and Petrosian R magnitudes for the SAMI survey GAMA targets is given here:
This is the list that we select from but not all of these targets will be observed.
If you specifically would like to know which objects have been observed so far, then contact jbryantphysics [dot] usyd [dot] edu [dot] au (Target Selection Working Group).
SAMI cluster targets
The GAMA regions do not contain any massive clusters at z<0.1, so we are separately targeting galaxies in 8 specific clusters. The clusters to be targeted are listed below.
Location of SAMI Galaxy Survey Fields
The figure below shows the distribution of the SAMI GAMA and cluster regions compared to other related imaging and spectroscopic galaxy surveys.
