  • Gravitational lensing reveals ionizing ultraviolet photons escaping from a distant galaxy 
    Rivera-Thorsen, Thøger Emil Juul; Dahle, Håkon; Chisholm, John; Florian, Michael K.; Gronke, Max Balthasar; Rigby, Jane R.; Gladders, Michael D.; Mahler, Guillaume; Sharon, Keren; Bayliss, Matthew B. (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    During the epoch of reionization, neutral gas in the early Universe was ionized by hard ultraviolet radiation emitted by young stars in the first galaxies. To do so, ionizing ultraviolet photons must escape from the host ...
  • Hubble Constant Measurement from Three Large-separation Quasars Strongly Lensed by Galaxy Clusters 
    Napier, Kate; Sharon, Keren; Dahle, Håkon; Bayliss, Matthew; Gladders, Michael D.; Mahler, Guillaume; Rigby, Jane R.; Florian, Michael (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Tension between cosmic microwave background–based and distance ladder–based determinations of the Hubble constant H0 motivates the pursuit of independent methods that are not subject to the same systematic effects. A ...
  • Small Region, Big Impact: Highly Anisotropic Lyman-continuum Escape from a Compact Starburst Region with Extreme Physical Properties 
    Kim, Keunho J.; Bayliss, Matthew B.; Rigby, Jane R.; Gladders, Michael D.; Chisholm, John; Sharon, Keren; Dahle, Håkon; Rivera-Thorsen, Thøger Emil Juul; Florian, Michael K.; Khullar, Gourav; Mahler, Guillaume; Mainali, Ramesh; Napier, Kate A.; Navarre, Alexander; Owens, M. Riley; Roberson, Joshua (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Abstract Extreme, young stellar populations are considered to be the primary contributor to cosmic reionization. How the Lyman continuum (LyC) escapes these galaxies remains highly elusive, and it is challenging ...
