VizieR Online Data Catalog: HETDEX [OIII] emitters. I. Low-z galaxies (Indahl+, 2021)
Abstract
We constructed our sample of low-metallicity [OIII] emitters from an early internal HETDEX DR (iHDR1) consisting of a catalog of every emission-line detection in the 8.16deg2 of the survey completed between 2017 January 3 and 2019 February 9. The HETDEX survey is conducted with the Visible Integral Field Unit Spectrograph (VIRUS), which covers 3500-5500Å at an R~800 (2Å/pixel dispersion).
Each galaxy in our sample was followed up with the LRS2 Red unit, an IFS on the Hobby-Eberly Telescope at McDonald Observatory between 2019-10-30 and 2020-05-29. See Section 2.2. Photometric data were collected from several surveys to perform SED fitting of our sample. These data are discussed in detail in Section 2.4. (4 data files).- Publication:
