    • A new, faint population of X-ray transients 
      Bauer, Franz E.; Treister, Ezequiel; Schawinski, Kevin; Schulze, Steve; Luo, Bin; Alexander, David M.; Brandt, William N.; Comastri, Andrea; Forster, Francisco; Gilli, Roberto; Kann, David Alexander; Maeda, Keiichi; Nomoto, Ken'ichi; Paolillo, Maurizio; Ranalli, Piero; Schneider, Donald P.; Shemmer, Ohad; Tanaka, Masaomi; Tolstov, Alexey; Tominaga, Nozomu; Tozzi, Paolo; Vignali, Cristian; Wang, Junxian; Xue, Yongquan; Yang, Guang (Oxford University Press, 2017)
      © 2017 The Authors. We report on the detection of a remarkable new fast high-energy transient found in the Chandra Deep Field-South, robustly associated with a faint (mR = 27.5mag, zph ~2.2) host in the CANDELS survey. The ...
    • 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, ...
    • Type 2 AGN host galaxies in the Chandra-COSMOS Legacy Survey: No evidence of AGN-driven Quenching 
      Suh, Hyewon; Civano, Francesca; Hasinger, Guenther; Lusso, Elisabeta; Lanzuisi, Giorgio; Marchesi, Stefano; Trakhtenbrot, Benny; Allevato, Viola; Cappelluti, Nico; Capak, Peter L.; Elvis, Martin; Griffiths, Richard E.; Laigle, Clotilde; Lira Teillery, Paulina; Riguccini, Laurie; Rosario, David J.; Salvato, Mara; Schawinski, Kevin; Vignali, Cristian (IOP Publishing, 2017-06-01)
      We investigate the star formation properties of a large sample of similar to 2300 X-ray-selected Type 2 Active Galactic Nuclei (AGNs) host galaxies out to z similar to 3 in the Chandra COSMOS Legacy Survey in order to ...
