Nonperturbative structure in coupled axion sectors and implications for direct detection |
Abstract: Pairs of misalignment-produced axions with nearby masses can experience a
nonlinear resonance that leads to enhanced direct and astrophysical signatures
of axion dark matter. In much of the relevant parameter space,
self-interactions cause axion fluctuations to become nonperturbative and to
collapse in ... | https://export.arxiv.org/pdf/2208.05501 |

Constraining the physical properties of the first lensed $z\sim10-16$ galaxy candidates with JWST |
Abstract: The first deep-field observations of the JWST have immediately yielded a

SED-fitting analysis of the 15 gravitationally lensed $z\sim10-16$ galaxy
