    Anna Reckin and Nicola Simpson - Norwich : European Poetry Festival 2024 European Poetry Festival : Norwich - July 4th 2024 at The Forum Auditorium in partnership with National Centre for Writing : https://www.europeanpoetryfestival.co... The 2024 European Poetry Festival visited Norwich, in partnership with the National Centre for Writing to present an evening celebrating poetry, performance and the potentials of collaboration to a bustling audience in the heart of the city. Pairing some of the finest poets of the thriving Norwich poetry scene alongside writers visiting from across Europe, over a dozen poets presented new works made for the night, spanning languages, literatures and the European continent. Featuring Thor Magnus Tangerås and George Szirtes / Helen Ivory and Agnieszka Studzinka / Ane Thon Knutsen and Sam Jordison / Ondřej Macl and Cat Woodward / Philip Terry and Doug Jones / Tim Postovit and Matt Sokulsky / Ko Ko Thett and Adrian Tissier / Anna Reckin and Nicola Simpson / Matthew Gregory et a

    Catastrogenesis: DM, GWs, and PBHs from ALP string-wall networks

    No full text
    Axion-like particles (ALPs), a compelling candidate for dark matter (DM), are the pseudo Nambu-Goldstone bosons of a spontaneously and explicitly broken global U(1)U(1) symmetry. When the symmetry breaking happens after inflation, the ALP cosmology predicts the formation of a string-wall network which must annihilate early enough, producing gravitational waves (GWs) and primordial black holes (PBHs), as well as non-relativistic ALPs. We call this process catastrogenesis. We show that, under the generic assumption that the potential has several degenerate minima, GWs from string-wall annihilation at temperatures below 100 eV could be detected by future CMB and astrometry probes, for ALPs with mass from 101610^{-16} to 106eV10^{6}\,\rm eV. In this case, structure formation could limit ALPs to constitute a fraction of the DM and the annihilation would produce mostly ``stupendously large" PBHs. For larger annihilation temperatures, ALPs can constitute 100%100\% of DM, and the annihilation could produce supermassive black holes with a mass of up to 109M10^9\, M_\odot as found at the center of large galaxies. Therefore our model could solve two mysteries, the nature of the DM and the origin of these black holes.Comment: 26 pages, 5 figures. Matches published versio
