  • Polarimetric and spectroscopic study of radio quiet weak emission line quasars 
    Kumar, P; Chand, H; Srianand, R; Stalin, C. S; Petitjean, P; Gopal-Krishna (Oxford University Press on behalf of the Royal Astronomical Society, 2018-10)
    A small subset of optically selected radio-quiet quasars showing weak or no emission lines may turn out to be the elusive radio-quiet BL Lac objects, or simply be radio-quiet QSOs with a still-forming/shielded broad line ...
  • The Sloan Digital Sky Survey Quasar Catalog: Sixteenth Data Release 
    Lyke, Brad W; Higley, Alexandra N; McLane, J. N; Schurhammer, D. P; Myers, A. D; Ross, A. J; Dawson, K; Chabanier, S; Martini, P; Busca, N. G; Mas des Bourboux, Helion du; Salvato, Mara; Streblyanska, A; Zarrouk, P; Burtin, E; Anderson, S. F; Bautista, J; Bizyaev, D; Brandt, W. N; Brinkmann, J; Brownstein, J. R; Comparat, J; Green, Paul; de la Macorra, Axel; Munoz Gutierrez, Andrea; Hou, Jiamin; Newman, J. A; Palanque-Delabrouille, N; Paris, I; Percival, W. J; Petitjean, P; Rich, J; Rossi, G; Schneider, D. P; Smith, Alexander; Vivek, M; Weaver, Benjamin A (IOP Publishing, 2020-09)
    We present the final Sloan Digital Sky Survey IV (SDSS-IV) quasar catalog from Data Release 16 of the extended Baryon Oscillation Spectroscopic Survey (eBOSS). This catalog comprises the largest selection of spectroscopically ...
  • The WIRCAM Deep Infrared Cluster Survey I. Groups and clusters at z  ≳  1.1 
    Bielby, R. M; Finoguenov, A; Tanaka, M; McCracken, H. J; Daddi, E; Hudelot, P; Ilbert, O; Kneib, J. P; Le Fèvr, O; Mellier, Y; Nandra, K; Petitjean, P; Srianand, R; Stalin, C. S; Willott, C. J (EDP Sciences, 2010-12)
    We use a combination of CFHTLS deep optical data, WIRcam Deep Survey (WIRDS) near-infrared data and XMM-Newton survey data to identify z ≳ 1.1 clusters in the CFHTLS D1 and D4 fields. Counterparts to such clusters can not ...
  • X-ray and optical properties of broad absorption line quasars in the Canada–France–Hawaii Telescope Legacy Survey 
    Stalin, C. S; Srianand, R; Petitjean, P (Wiley-Blackwell, 2011-05)
    We study the X-ray and optical properties of 16 broad absorption line (BAL) quasars detected in a ≈3 deg2 region common to the wide synoptic (W-1) component of the Canada–France–Hawaii Telescope Legacy Survey (CFHTLS) and ...
