Non-linear Dynamics and Primordial Black Hole Formation During Kination
Cheng Cheng, Panagiotis Giannadakis, Lucien Heurtier +1
We investigate the effects of large scalar inhomogeneities during the kination epoch, a period in which the universe's dynamics are dominated by the kinetic energy of a scalar fiel…
Indirect detection of the QCD axion
Luca Visinelli, Bradley Johnson, Bradley J. Kavanagh +3
The QCD axion, originally proposed to solve the strong CP problem in QCD, is a prominent candidate for dark matter (DM). In the presence of strong magnetic fields, such as those ar…
Search for a gravitational wave background from primordial black hole binaries using data from the first three LIGO-Virgo-KAGRA observing runs
Tore Boybeyi, Sebastien Clesse, Sachiko Kuroyanagi +1
Using the cross-correlation data from the first three observing runs of the LIGO-Virgo-KAGRA Collaboration, we search for a gravitational-wave background (GWB) from primordial blac…
Interference in Fuzzy Dark Matter Filaments: Idealised Models and Statistics
Tim Zimmermann, David J. E. Marsh, Keir K. Rogers +2
Fuzzy (wave) dark matter (FDM), the dynamical model underlying an ultralight bosonic dark matter species, produces a rich set of non-gravitational signatures that distinguishes it…
What is the origin of the JWST SMBHs?
John Ellis, Malcolm Fairbairn, Juan Urrutia +1
We present a new semi-analytical model for the evolution of galaxies and supermassive black holes (SMBHs) that is based on the extended Press-Schechter formalism and phenomenologic…
Improved Halo Model Calibrations for Mixed Dark Matter Models of Ultralight Axions
Tibor Dome, Simon May, Alex Laguë +5
We study the implications of relaxing the requirement for ultralight axions to account for all dark matter in the Universe by examining mixed dark matter (MDM) cosmologies with axi…
