    • Exploratory X-Ray monitoring of luminous radio quiet quasars at high redshift: no evidence for evolution ... 
      Shemmer, Ohad; Brandt, W. N.; Paolillo, Maurizio; Kaspi, Shai; Vignali, Cristian; Lira Teillery, Paulina; Schneider, Donald P. (IOP Publishing Ltd, 2017)
      We report on the second installment of an X-ray monitoring project of seven luminous radio-quiet quasars (RQQs). New Chandra observations of four of these, at 4.10 <= z <= 4.35, yield a total of six X-ray epochs per source, ...
    • THE SDSS-III BARYON OSCILLATION SPECTROSCOPIC SURVEY: THE QUASAR LUMINOSITY FUNCTION FROM DATA RELEASE NINE 
      Ross, Nicholas P.; McGreer, I.; White, Martin; Richards, Gordon; Myers, Adam D.; Palanque-Delabrouille, Nathalie; Strauss, Michael; Anderson, Scott; Shen, Yue; Brandt, W.

H.; York, Donald (The American Astronomical Society, 2013)
      We present a new measurement of the optical quasar luminosity function (QLF), using data from the Sloan Digital Sky Survey-III: Baryon Oscillation Spectroscopic Survey (SDSS-III: BOSS). From the SDSS-IIIData ReleaseNine, a ...

(IOP Publishing, 2019)
      We report the detection of a hot Jupiter (M-p = 1.75(-0.17)(+0.14) M-J, R-p = 1.38 +/- 0.04R(J)) orbiting a middle-aged star (log g = 4.152(-0.043)(+0.030)) in the Transiting Exoplanet Survey Satellite (TESS) southern ...
