Whispers from the dark side: Confronting light new physics with NANOGrav data

Wolfram Ratzinger et al.

Summary: The NANOGrav collaboration has recently observed first evidence of a gravitational wave background in pulsar timing data, which could be due to new physics. They found that the signal can be well fit with peaked spectra expected from phase transitions or from the dynamics of axion-like particles in the early universe.

More axions from strings

Marco Gorghetto et al.

Summary: Clear evidence of scaling violations in the contribution to QCD axion dark matter abundance from string defects is found, suggesting a large number of axions from strings. Nonlinearities around the QCD scale are shown to play a crucial role in determining the final abundance, resulting in a substantially stronger lower bound on the QCD axion mass in the post-inflationary scenario compared to the naive estimate from misalignment.

Axion miniclusters made easy

David Ellis et al.

Summary: The study presents a modified peak patch excursion set formalism for computing the mass and size distribution of QCD axion miniclusters, based on a fully non-Gaussian initial density field obtained from numerical simulations of axion string decay. Strong agreement with N-body simulations is found at significantly lower computational cost. The method employs a spherical collapse model and provides fitting functions for the modified barrier in the radiation era.
