    Dear all,<br>
    <br>
    On <b>Wed Mar 14, 13:15, room C6:1038</b> we will have a special
    C&G working group session devoted to discussing the <b>EDGES</b>
    detection of the 21-cm signal, and its possible implications for
    physics <b>beyond the Standard Model</b>.<br>
    <br>
    In preparation for the discussion, here is a list of papers related
    to the EDGES detection you might want to look at, divided by topic.<br>

    If you want to stay up-to-date with papers discussing the EDGES
    result and proposing explanations, this might be a good place to
    start:
