    Dear All,

    Please see attached and below invitation to a seminar to be presented by Dr Ren?e Hlozek from Princeton University.

    Title: A search for ultra-light axions using precision cosmological data

    Abstract: Ultra-light axions (ULAs) with masses in the range 10^{ -33} eV 10^{ -24} eV, ULAs are indistinguishable from standard cold dark matter on the length scales probed, and are thus allowed by these data. For m < 10^{ -32} eV, ULAs are allowed to compose a significant fraction of the dark energy.

    Kind regards
