  1. 1. An Absorption Feature in Observations with EDGES Mid-Band
    Prof. Raul Monsalve (Department of Physics and McGill Space Institute McGill University)
    30/03/2020, 14:00

    I will present results from observations with the EDGES Mid-Band system. This instrument measured in 2018 the sky-averaged radio spectrum in the range ~60-120 MHz. It used a blade antenna that is ~30% smaller than the Low-Band antennas used for the measurements in Bowman et al. (2018). Despite the smaller antenna, in the Mid-Band spectrum we identify an absorption feature that is consistent...

  2. 3. Dark Matter in Light of the 21cm EDGES Signal

  3. 12. Complementarity of CMB and 21cm for the study of dark matter properties and exotic reionization
    Prof. Vivian Poulin (Montpellier Univ. )
    30/03/2020, 17:00

    In this talk, I will review how the CMB and 21cm can be used to study dark matter (DM) properties, as well as sources of exotic (early) reionization. I will first discuss how the CMB can provide strong constraints on scattering between DM and baryons, and probe the parameter space suggested by the EDGES anomaly. I will then introduce models that could reconcile the EDGES anomaly while being...

  10. 8. Modeling the 21-cm signal from the Cosmic Dawn
    Prof. Andrei Mesinger (Scuola Normale Superiore)
    01/04/2020, 11:15

    The birth of the first stars, black holes and galaxies heralded the end of the cosmic Dark Ages and the beginning of the Cosmic Dawn. The light from these objects heated and ionized almost every atom in existence, culminating in the Epoch of Reionization: the final major phase change of the Universe. This final frontier of astrophysical cosmology is undergoing a transition from an...
