VizieR Online Data Catalog: 4 AGN optical spectra (Simmonds+, 2016)

We targeted with dedicated Chandra observations the four most extreme ELGs reported by Izotov and Thuan (2008ApJ...687..133I) (J1025+1402, J1047+0739, J0045+1339, and J1222+3602). For completeness, we also report the results of archival Chandra observations for three weaker objects (J1536+3122, J0840+4707, and J1404+5423) in the parent Izotov et al. (2007ApJ...671.1297I) sample which also have broad Hα emission lines.

New optical spectra for galaxies J0045+1339, J1025+1402, J1047+0739, and J1222+3602 were obtained using the Apache Point Observatory (APO) 3.5m telescope using the Dual Imaging Spectrograph (DIS) in both the blue and red wavelength ranges. The sources were observed on several occasions between 2007-2015.

New optical spectra for galaxies J0045+1339 and J1222+3602 were obtained using the MODS instrument on the Large Binocular Telescope (LBT) on UT 2013 October 27 and UT 2015 May 18, respectively.
