Cluster cosmology constraints from the 2500 deg2 SPT-SZ survey: inclusion of weak gravitational lensing data from Magellan and the Hubble space telescope
We derive cosmological constraints using a galaxy cluster sample selected from the 2500
deg 2 SPT-SZ survey. The sample spans the redshift range 0.25< z< 1.75 and contains 343 …

Formation and mass growth of axion stars in axion miniclusters
B Eggemeier, JC Niemeyer - Physical Review D, 2019 - APS
We study the formation and the subsequent mass growth of axion stars inside axion
miniclusters. Numerically solving the Schrödinger-Poisson equations with realistic initial …

Transient radio lines from axion miniclusters and axion stars
Gravitationally bound clumps of dark matter axions in the form of “miniclusters” or even
denser “axion stars” can generate strong radio signals through axion-photon conversion …

Simulations of axion minihalos
The axion, motivated as a solution to the strong CP problem, is also a viable dark matter
candidate. The axion field takes random values in causally disconnected regions if the …
