    • The neutral hydrogen cosmological mass density at z = 5 
      Crighton, Neil; Murphy, Michael; Xavier, J.; Worseck, Gábor; Rafelski, Marc; Becker, George; Ellison, Sara L.; Fumagalli, Michele; López Morales, Sebastián; Meiksin, Avery; O’Meara, John (The Royal Astronomical Society, 2015)
      We present the largest homogeneous survey of z > 4.4 damped Lyα systems (DLAs) using the spectra of 163 QSOs that comprise the Giant Gemini GMOS (GGG) survey. With this survey we make the most precise high-redshift ...
    • The cosmic ultraviolet baryon survey (CUBS) - III. Physical properties and elemental abundances of Lyman-limit ... 
      Zahedy, Fakhri S.; Chen, Hsiao-Wen; Cooper, Thomas M.; Boettcher, Erin; Johnson, Sean D.; Rudie, Gwen C.; Chen, Mandy C.; Cantalupo, Sebastiano; Cooksey, Kathy L.; Faucher Giguere, Claude-Andre; Greene, Jenny E.; López Morales, Sebastián Víctor Claudio; Mulchaey, John S.; Penton, Steven; Petitjean, Patrick; Putman, Mary E.; Rafelski, Marc; Rauch, Michael; Schaye, Joop; Simcoe, Robert A.; Walth, Gregory L. (Oxford, 2021)
      We present a systematic investigation of physical conditions and elemental abundances in four optically thick Lyman-limit systems (LLSs) at z = 0.36-0.6 discovered within the cosmic ultraviolet baryon survey (CUBS). Because ...
    • The cosmic ultraviolet baryon survey (CUBS) IV: The complex multiphase circumgalactic medium as revealed ... 
      Cooper, Thomas J.; Rudie, Gwen C.; Chen, Hsiao-Wen; Johnson, Sean D.; Zahedy, Fakhri S.; Chen, Mandy C.; Boettcher, Erin; Walth, Gregory L.; Cantalupo, Sebastiano; Cooksey, Kathy L.; Faucher Giguere, Claude Andre; Greene, Jenny E.; López Morales, Sebastián Víctor Claudio; Mulchaey, John S.; Penton, Steven; Petitjean, Patrick; Putman, Mary E.; Rafelski, Marc; Rauch, Michael; Schaye, Joop; Simcoe, Robert A. (Oxford, 2021)
      We present a detailed study of two partial Lyman limit systems (pLLSs) of neutral hydrogen column density N-HI approximate to ( 1 - 3) x 10(16) cm(-2 )discovered at z = 0.5 in the Cosmic Ultraviolet Baryon Survey (CUBS). ...
