  • Origin of Metals around Galaxies. I. Catalogs of Metal-line Absorption Doublets from High-resolution Quasar Spectra 
    Mas Ribas, Lluis; Riemer-Sørensen, Signe; Hennawi, Joseph F; Miralda-Escudé, Jordi; O'Meara, John M.; Pérez-Ràfols, Ignasi; Murphy, Michael T.; Webb, John K. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    We present the first paper of the series Origin of Metals around Galaxies, which aims to explore the origin of the metals observed in the circumgalactic and intergalactic media. In this work we extract and build catalogs ...
  • Revealing the Warm and Hot Halo Baryons via Thomson Scattering of Quasar Light 
    Mas Ribas, Lluis; Hennawi, Joseph F (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    The baryonic content and physical properties of the warm and hot (105 lesssim T lesssim 107 K) phases of the circumgalactic medium (CGM) are poorly constrained owing to the lack of observables probing the requisite range ...
