    • 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

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 ...
    • Understanding the structure of school staff advice relations: an inferential social network perspective 

      Ortega Ferrand, Lorena; Boda, Zsófia; Thompson, Ian; Daniels, Harry (Elsevier, 2020)
      Understanding the structure of staff advice relationships and the factors that facilitate (and hinder) the flow of resources within schools is key to school improvement. Our study examines school staff advice networks for ...
