  1. 1. seminar 1: "First Identification of a CMB Lensing Signal Produced by 1.5 Million Galaxies at z∼4"
    Dr Yuichi Harikane (ICRR)
    05/10/2022, 13:00

    We report the first detection of the dark matter distribution around Lyman break galaxies (LBGs) at the redshift of z~4 through the cosmic microwave background (CMB) lensing measurements with the public Planck PR3 κ map. The LBG sample consists of 1473106 objects at z∼4 that are identified in a total area of 305  deg2 observed by the Subaru/Hyper Suprime-Cam survey. After careful...

  2. 2. Seminar 2: "Searches for Dark Matter with Cherenkov telescopes: Latest results and a glimpse into the future"
    Dr Moritz Hütten
    31/10/2022, 14:45

    The quest for Dark Matter is a since long unsolved puzzle of modern physics. Imaging Atmospheric Cherenkov telescopes, like MAGIC located at Roque de los Muchachos Observatory on La Palma, have so far searched almost 1000 hours of their data for gamma-ray signals from annihilating or decaying heavy (>GeV) Dark Matter particles. Also, the next-generation Cherenkov Telescope Array (CTA) is under...
