    • The 31 deg2 release of the stripe 82 x-ray survey: the point source catalog 
      La Massa, Stephanie M.; Urry, C. Megan; Cappelluti, Nico; Böhringer, Hans; Comastri, Andrea; Glikman, Eilat; Richards, Gordon; Ananna, Tonima; Brusa, Marcella; Cardamone, Carie; Chon, Gayoung; Civano, Francesca; Farrah, Duncan; Gilfanov, Marat; Green, Paul; Komossa, S.; Lira Teillery, Paulina; Makler, Martin; Marchesi, Stefano; Pecoraro, Robert; Ranalli, Piero; Salvato, Mara; Schawinski, Kevin; Stern, Daniel; Treister, Ezequiel; Viero, Marco (Cornell University, 2015)
      We release the next installment of the Stripe 82 X-ray survey point-source catalog, which currently covers 31.3 deg2 of the Sloan Digital Sky Survey (SDSS) Stripe 82 Legacy field. In total, 6181 unique X-ray sources are ...
    • ALMA Observations of Quasar Host Galaxies at z similar or equal to 4.8 
      Nguyen, Nathen H.; Lira Teillery, Paulina; Trakhtenbrot, Benny; Netzer, Hagai; Cicone, Claudia; Maiolino, Roberto; Shemmer, Ohad (IOP Publishing, 2020)
      We present ALMA Band 7 data of the [C II] lambda 157.74 mu m emission line and underlying far-IR (FIR) continuum for 12 luminous quasars at z similar or equal to 4.8 powered by fast-growing supermassive black holes (SMBHs). ...
    • Black hole fueling and coalescence in galaxy mergers 
      Valle, Luciano del; Prieto, Joaquín; Escala Astorquiza, Andrés (Wiley, 2019)
      We study the gas accretion and orbital decay of super-massive black hole (SMBH) pairs in the nuclear region of galaxy merger remnants, where a large amount of gas is expected to accumulate. For that purpose, we perform ...
    • Reverberation mapping of High - z, High - luminosity quasars 
      Lira Teillery, Paulina; Botti, Ismael; Kaspi, Shai; Netzer, Hagai (Frontiers media SA, 2018)
      We present Reverberation Mapping results after monitoring a sample of 17 high-z, high-luminosity quasars for more than 10 years using photometric and spectroscopic capabilities. Continuum and line emission flux variability ...
    • The effect of nuclear gas distribution on the mass determination of supermassive black holes 
      Mejía Restrepo, J. E.; Lira Teillery, Paulina; Netzer, H.; Trakhtenbrot, B.; Capellupo, D. M. (Nature Publishing Group, 2018)
      Supermassive black holes reside in the nuclei of most galaxies. During their active episodes, black holes are powered by accretion discs where gravitational energy is converted into radiation(1). Accurately determining ...
