  • A bright-lensed galaxy at z = 5.4 with strong Ly α emission 
    McGreer, Ian D; Clément, Benjamin; Mainali, Ramesh; Stark, Daniel P.; Gronke, Max Balthasar; Dijkstra, Mark; Fan, Xiaohui; Bian, Fuyan; Frye, Brenda; Jiang, Linhua; Kneib, Jean-Paul; Limousin, Marceau; Walth, Gregory (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    We present a detailed study of an unusually bright, lensed galaxy at z = 5.424 discovered within the CFHTLS imaging survey. With an observed flux ofiAB =23.0, J141446.82+544631.9 is one of the brightest galaxies known at ...
  • 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 ...
  • The Connection Between Galactic Outflows and the Escape of Ionizing Photons 
    Mainali, Ramesh; Rigby, Jane R.; Chisholm, John; Bayliss, Matthew; Bordoloi, Rongmon; Gladders, Michael D.; Rivera-Thorsen, T. Emil; Dahle, Håkon; Sharon, Keren; Florian, Michael; Berg, Danielle A.; Sharma, Soniya; Owens, M. Riley; Kjellgren, Karin; Kim, Keunho J.; Wayne, Julia (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Abstract We analyze spectra of a gravitationally lensed galaxy, known as the Sunburst Arc, that is leaking ionizing photons, also known as the Lyman continuum (LyC). Magnification from gravitational lensing permits ...
  • The Cosmic Telescope That Lenses the Sunburst Arc, PSZ1 G311.65-18.48: Strong Gravitational Lensing Model and Source Plane Analysis 
    Sharon, Keren; Mahler, Guillaume; Rivera-Thorsen, T. Emil; Dahle, Håkon; Gladders, Michael D.; Bayliss, Matthew B.; Florian, Michael K.; Kim, Keunho J.; Khullar, Gourav; Mainali, Ramesh; Napier, Kate A.; Navarre, Alexander; Rigby, Jane R.; Remolina González, Juan David; Sharma, Soniya (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    We present a strong-lensing analysis of the cluster PSZ1 G311.65−18.48, based on Hubble Space Telescope imaging, archival VLT/MUSE spectroscopy, and Chandra X-ray data. This cool-core cluster (z = 0.443) lenses the brightest ...
