    • A Magellan M2FS spectroscopic survey of galaxies at 5.5 < z < 6.8: program overview and a sample of the brightest Ly alpha emitters 

      Jiang, Linhua; Shen, Yue; Bian, Fuyan; Zheng, Zhen Ya; Wu, Jin; Oyarzún, Grecco A.; Blanc Mendiberri, Guillermo; Fan, Xiaohui; Ho, Luis C.; Infante, Leopoldo; Wang, Ran; Wu, Xue Bing; Mateo, Mario; Bailey, John I.; Crane, Jeffrey D.; Olszewski, Edward W; Shectman, Stephen; Thompson, Ian; Walker, Matthew G. (IOP Publishing Ltd, 2017)
      We present a spectroscopic survey of high-redshift, luminous galaxies over four square degrees on the sky, aiming to build a large and homogeneous sample of Ly alpha emitters (LAEs) at z approximate to 5.7 and 6.5, and ...
    • CTQ 839: Candidate for the smallest projected separation binary quasar 

      Morgan, Nicholas D.; Burley, Greg; Costa Hechenleitner, Edgardo; Maza Sancho, José; Persson, S. E.; Ruiz González, María Teresa; Schechter, Paul L.; Thompson, Ian; Winn, Joshua N. (2000-03)
      We report the discovery of the new double quasar CTQ 839. This B\18.3, radio-quiet quasar pair is separated by 2A.1 in BRI and H Ðlters, with magnitude di erences of *mB\2.5, *mR\*mI\1.9, and *mH\2.3. Spectral observations ...
    • MagAO Imaging of long-period Objects (MILO). I. A Benchmark M Dwarf Companion Exciting a Massive Planet around the Sun-like star HD 7449 

      Rodigas, Timothy; Arriagada, Pamela; Faherty, Jackie; Anglada Escudé, Guillem; Kaib, Nathan; Butler, R. Paul; Shectman, Stephen; Weinberger, Alycia; Males, Jared; Morzinski, Katie; Close, Laird; Hinz, Philip; Crane, Jeffrey; Thompson, Ian; Teske, Johanna; Díaz, Matías; Minniti, Dante; López Morales, Mercedes; Adams, Adam; Boss, Alan (IOP, 2016)
      We present high-contrast Magellan adaptive optics images of HD 7449, a Sun-like star with one planet and a longterm radial velocity (RV) trend. We unambiguously detect the source of the long-term trend from 0.6–2.15 μmat ...
    • Optical and infrared photometry of the nearby Type Ia supernovae 1999ee, 2000bh, 2000ca, and 2001ba 

      Krisciunas, Kevin; Phillips, Mark M.; Suntzeff, Nicholas B.; Persson, S. E.; Hamuy Wackenhut, Mario; Antezana, Roberto; Candia, Pablo; Clocchiatti, Alejandro; L. DePoy, Darren; Germany, Lisa M.; Gonzalez, Luis; Gonzalez, Sergio; Krzeminski, Wojtek; Maza Sancho, José; Nugent, Peter E.; Qiu, Yulei; Rest, Armin; Roth, Miguel; Stritzinger, Maximilian; Strolger, L. G.; Thompson, Ian; Williams, T. B.; Wischnjewsky, Marina (IOP Publishing, 2004-03)
      We present near-infrared photometry of the Type Ia supernova (SN) 1999ee; also, optical and infrared photometry of the Type Ia SNe 2000bh, 2000ca, and 2001ba. For SNe 1999ee and 2000bh, we present the first-ever SN ...
