    • Levesque, Emily M.; Bloom, Joshua S.; Butler, Nathaniel R.; Perley, Daniel; Cenko, S. Bradley; Prochaska, Xavier; Kewley, Lisa; Bunker, Andrew; Chen, Hsiao-Wen; Chornock, Ryan; Filippenko, Alexei V.; Glazebrook, Karl; López Morales, Sebastián; Masiero, Joseph; Modjaz, Maryam; Morgan, Adam; Poznanski, Dovi (2010)
      We present the discovery of an absorption-line redshift of z = 2.609 for GRB 090426, establishing the first firm lower limit to a redshift for a gamma-ray burst (GRB) with an observed duration of <2 s.With a rest-frame ...
    • Prochter, Gabriel E.; Prochaska, Jason X.; Chen, Hsiao-Wen; Bloom, Joshua S.; Dessauges-Zavadsky, Miroslava; Foley, Ryan J.; López Morales, Sebastián; Pettini, Max; Dupree, Andrea K.; Guhathakurta, P. (UNIV CHICAGO PRESS, 2006-09-10)
      We report on a survey for strong ( rest equivalent width W-r >= 1 angstrom) intervening Mg II systems along the sight lines to long-duration gamma-ray bursts (GRBs). The GRB spectra that comprise the survey have a heterogeneous ...

Ivanov; Krzeminski, Wojtek; Kulesa, Craig; McCarthy, Patrick; Moro Martín, Amaya; Muena, César; Noriega-Crespo, Alberto; Persson, S. E.; Pinto, Philip A.; Roth, Miguel; Rubenstein, Eric P.; Stanford, S. Adam; Stringfellow, Guy S.; Zapata, Abner; Porter, Alain; Wischnjewsky, Marina (IOP Publishing, 2004-12)
      We present optical and/or infrared photometry of the Type Ia supernovae SN 1991T, SN 1991bg, SN 1999ek, SN 2001bt, SN 2001cn, SN 2001cz, and SN 2002bo. All but one of these supernovae have decline rate parameters, ...
    • 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 ...
    • 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). ...
