1. Long-term dynamics of cosmological axion strings / Kawasaki, Masahiro ; Sekiguchi, Toyokazu ; Yamaguchi, Masahide ; Yokoyama, Jun’ichi
We present the results of a new field-theoretic simulation of cosmological axion strings, which are eight times longer than previous ones. [...]

3. Radio telescope search for the resonant conversion of cold dark matter axions from the magnetized astrophysical sources / Huang, Fa Peng ; Kadota, Kenji ; Sekiguchi, Toyokazu ; Tashiro, Hiroyuki
We study the conditions for the adiabatic resonant conversion of the cold dark matter (CDM) axions into photons in the astrophysically sourced strong magnetic fields such as those in the neutron star magnetosphere. [...]

6. Topological defects and nano-Hz gravitational waves in aligned axion models / Higaki, Tetsutaro ; Jeong, Kwang ; Kitajima, Naoya ; Sekiguchi, Toyokazu ; et al
We study the formation and evolution of topological defects in an aligned axion model with multiple Peccei-Quinn scalars, where the QCD axion is realized by a certain combination of the axions with decay constants much smaller than the conventional Peccei-Quinn breaking scale. [...]
