Pre-inflationary QCD axion stars after moduli domination
Edward Hardy, Noelia Sánchez González, Henry Stubbs +1
The growth of adiabatic density perturbations during an era of early matter domination induces fluctuations in pre-inflationary QCD axion dark matter across a broa…

Metastable cosmic strings are broken at the start
Lorenzo Tranchedone, Ethan Carragher, Edward Hardy +1
We show that metastable cosmic strings break at early times, either via finite-temperature effects or by attaching to pre-existing monopoles during network percolation. The resulti…

Holographic Generalised Gukov-Witten Defects
Pieter Bomans, Lorenzo Tranchedone
Spindle and disc solutions have received significant attention in recent literature. However, it is not entirely clear what these supergravity solutions represent in the dual SCFT.…
