  • Wide field high cadence CMB survey designs for Chilean telescopes 
    Ebina, Haruki; Keskitalo, Reijo; Borrill, Julian; Choi, Steve K.; Kisner, Theodore S.; Næss, Sigurd Kirkevold; Niemack, Michael D.; Stevens, Jason R. (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)
    We present new wide field survey strategies for Chilean Large Aperture Telescopes (LAT) measuring the Cosmic Microwave Background (CMB), which we call Sinusoidal Modulated High Cadence Survey Strategies. The strategies ...
  • Wormholes supported by hybrid metric-Palatini gravity 
    Capozziello, S.; Harko, T.; Koivisto, Tomi Sebastian; Lobo, F. S. N.; Olmo, G. J. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)
    Recently, a modified theory of gravity was presented, which consists of the superposition of the metric Einstein-Hilbert Lagrangian with an f(R) term constructed à la Palatini. The theory possesses extremely interesting ...
  • YZiCS: Unveiling the Quenching History of Cluster Galaxies Using Phase-space Analysis 
    Rhee, Jinsu; Smith, Rory; Choi, Hoseung; Contini, Emanuele; Jung, S. Lyla; Han, San; Yi, Sukyoung K. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    We used the time since infall (TSI) of galaxies, obtained from the Yonsei Zoom-in Cluster Simulation, and the star formation rate (SFR) from the Sloan Digital Sky Survey Data Release 10 to study how quickly the star formation ...
