    • A VLT/MUSE galaxy survey towards QSO Q1410: looking for a WHIM traced by BLAs in inter-cluster filaments 

      Pessa, Ismael; Tejos, Nicolás; Barrientos, Luis; Werk, Jessica; Bielby, Richard; Padilla, Nelson; Morris, Simón; Prochaska, J.; López Morales, Sebastián; Hummels, Cameron (Oxford University Press, 2018)
      Cosmological simulations predict that a significant fraction of the low-z baryon budget resides in large-scale filaments in the form of a diffuse plasma at temperatures T similar to 10(5)-10(7) K. However, direct observation ...
    • A VLT/MUSE galaxy survey towards QSO Q1410: Looking for aWHIM traced by BLAs in inter-cluster filaments 

      Pessa, Ismael; Tejos, Nicolás; Barrientos, L. Felipe; Werk, Jessica; Bielby, Richard; Padilla, Nelson; Morris, Simon L.; Prochaska, J. Xavier; Lopez, Sebastian; Hummels, Cameron (Oxford University Press, 2018)
      Cosmological simulations predict that a significant fraction of the low-z baryon budget resides in large-scale filaments in the form of a diffuse plasma at temperatures T ∼ 105 −107 K. However, direct observation of this ...
    • A coronagraphic absorbing cloud reveals the narrow-line region and extended Lyman alpha emission of QSO J0823+0529 

      Fathivavsari, H.; Petitjean, P.; Noterdaeme, P.; Paris, I.; Finley, H.; López Morales, Sebastián; Srianand, R.; Sánchez, P. S. (Oxford Univ Press, 2015)
      We report long-slit spectroscopic observations of the quasar SDSS J082303.22+052907.6 (z(C IV) similar to 3.1875), whose broad-line region (BLR) is partly eclipsed by a strong damped Lyman alpha (DLA; logN(H I) = 21.7) ...
    • A coronagraphic absorbing cloud reveals the narrow-line region and extended Lyman α emission of QSO J0823+0529 

      Fathivavsari, H.; Petitjean, P.; Noterdaeme, P.; Paris, I.; Finley, H.; López Morales, Sebastián; Srianand, R.; Sánchez, Paula (Royal Astronomical Society, 2015)
      We report long-slit spectroscopic observations of the quasar SDSS J082303.22+052907.6 (zC IV ∼ 3.1875), whose broad-line region (BLR) is partly eclipsed by a strong damped Lyman α (DLA; logN(H I) = 21.7) cloud. This ...
    • The Lyman α forest power spectrum from the XQ-100 Legacy Survey 

      Irsic, Vid; Viel, Matteo; Berg, Trystyn A. M.; D'Odorico, Valentina; Haehnelt, Martin G.; Cristiani, Stefano; Cupani, Guido; Kim, Tae-Sun; López Morales, Sebastián; Ellison, Sara; Becker, George D.; Christensen, Lise; Denney, Kelly D.; Worseck, Gabor; Bolton, James S. (Oxford University Press, 2017-05)
      We present the Lyman α flux power spectrum measurements of the XQ-100 sample of quasar spectra obtained in the context of the European Southern Observatory Large Programme ‘Quasars and their absorption lines: a legacy ...
    • The UVES large program for testing fundamental physics – II. Constraints on a change in μ towards quasar HE 0027−1836. 

      Rahmani, Hadi.; Wend, Martin; Srianand, Raghunathan; Noterdaeme, Pasquier; Petitjean, Patrick; Molaro, Paolo; Whitmore, Jonathan; Murphy, Michael; Centurion, M.; Fathivavsari, Hassan; D'Odorico, Sandro; Evans, Tyler; Levshakov, Sergei Anatolievich; López Morales, Sebastián; Martins, C. J. A. P.; Reimers, D.; Vladilo, Giovanni (Royal Astronomical of Society, 2013-08-22)
      We present an accurate analysis of the H2 absorption lines from the zabs ˜ 2.4018 damped Lyα system towards HE 0027-1836 observed with the Very Large Telescope Ultraviolet and Visual Echelle Spectrograph (VLT/UVES) as a ...
