TL;DR

The SAMI Galaxy Survey's third data release provides extensive integral-field spectroscopic data for over 3000 galaxies, including detailed 2D maps of their properties, enabling large-scale structure studies.

Contribution

This release is the first to include the full SAMI cluster galaxy sample, offering comprehensive spectral cubes and maps for a large, diverse galaxy dataset.

Findings

01

Data covers 3068 galaxies with detailed spectral and spatial information.

02

Includes the first data release of the SAMI cluster galaxy sample.

03

Provides publicly accessible, high-quality galaxy spectral maps.

Abstract

We have entered a new era where integral-field spectroscopic surveys of galaxies are sufficiently large to adequately sample large-scale structure over a cosmologically significant volume. This was the primary design goal of the SAMI Galaxy Survey. Here, in Data Release 3 (DR3), we release data for the full sample of 3068 unique galaxies observed. This includes the SAMI cluster sample of 888 unique galaxies for the first time. For each galaxy, there are two primary spectral cubes covering the blue (370-570nm) and red (630-740nm) optical wavelength ranges at spectral resolving power of R=1808 and 4304 respectively. For each primary cube, we also provide three spatially binned spectral cubes and a set of standardized aperture spectra. For each galaxy, we include complete 2D maps from parameterized fitting to the emission-line and absorption-line spectral data. These maps provide…
