Interesting Follow-up Targets

Back to Research By: Sarah True

The goal of this research is to use the Sloan Digital Sky Survey (SDSS) to data mine the spectra of quasars and identify redshifted absorption troughs as outflows. Of the thousands of objects found in the SDSS, the ones deemed most interesting are analyzed using custom computer software (Spectral Trough ID) that identifies doublets in the spectra, such as CIV, SiII, and NV. The tables below show our list of future targets for the William Herschel Telescope (WHT), the Very Large Telescope (VLT) at the European Southern Observatory in Chile, and the Hubble Space Telescope (HST).

• SDSS Search: Summer 2011: A complete search of the entire sky.
• SDSS Search: CII and SiIV: A summer 2010 search focused on CII and SIV.
• SDSS Search: Excited: A 2009 search focused on finding excited lines in the spectra.
• SDSS Search: Helium Excited: A search specifically of Helium excited in the universe.
• VLT X-Shooter Targets: Part I: A compliation of targets specifically for VLT X-Shooter with magnitude 18.0 < g < 18.2.
• VLT X-Shooter Targets: Part II: A compliation of targets specifically for VLT X-Shooter with magnitude 18.2 < g < 18.7.
• VLT X-Shooter Targets: Part III: A compliation of targets specifically for VLT X-Shooter with magnitude 18.7 < g < 18.8.
