Model implementations of axion dark matter from kinetic misalignment / Eröncel, Cem (Istanbul, Tech. U. ; Istanbul Aydin U.) ; Sato, Ryosuke (Osaka U.) ; Servant, Géraldine (DESY ; Hamburg U., Inst. Theor. Phys. II ; CERN) ; Sørensen, Philip (U. Padua, Dept. Phys. Astron. ; INFN, Padua)
The axion kinetic misalignment mechanism (KMM) opens the possibility of explaining dark matter for almost any axion mass and decay constant that are not accessible by the standard misalignment mechanism, in particular at low values of the axion decay constant (i.e. large coupling). [...]

Ultrahigh frequency primordial gravitational waves beyond the kHz: The case of cosmic strings / Servant, Géraldine (DESY ; Hamburg U., Inst. Theor. Phys. II ; CERN) ; Simakachorn, Peera (Valencia U., IFIC)
We investigate gravitational-wave backgrounds (GWBs) of primordial origin that would manifest only at ultra-high frequencies, from kilohertz to 100 gigahertz, and leave no signal at either LIGO, Einstein Telescope, Cosmic Explorer, LISA, or pulsar-timing arrays. We focus on GWBs produced by cosmic strings and make predictions for the GW spectra scanning over high-energy scale (beyond $10^{10}$ GeV) particle physics parameters. [...]

Axion cosmological histories / Servant, Geraldine (speaker) (Deutsches Elektronen-Synchrotron (DE))
I will illustrate how we can learn about axion physics by considering axion dynamics in the  early universe and its phenomenological signatures. This can be used to constrain its UV completions. [...]

Cosmology with the Laser Interferometer Space Antenna / LISA Cosmology Working Group Collaboration
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravitational-wave backgrounds and their implications for early universe and particle physics, from the MeV to the Planck scale. However, the range of potential cosmological applications of gravitational wave observations extends well beyond these two objectives. [...]

Higgs In Space! / Servant, Géraldine (CERN ; IPhT, Saclay)
In some classes of WIMP models, the Higgs boson could be copiously produced in association with a photon from dark matter annihilations or decays in our galaxy. The resulting photon spectrum possesses a line whose energy reflects the mass of the Higgs and of the WIMP and whose intensity depends on the WIMP spin and statistics. [...]
