A substantial fraction of stars can be found in wide binaries with projected separations between ∼10 ^2 and 10 ^5 au. In the standard lore of binary physics, these would evolve as effectively single stars that remotely orbit one another on stationa

The spatial distribution of galaxies and their gravitational lensing signal offer complementary tests of galaxy formation physics and cosmology. However, their synergy can only be fully exploited if both probes are modelled accurately and consistentl

The effect of stellar encounters on the dark matter annihilation signal from prompt cusps

Autor: Jens Stücker, Go Ogiya, Simon D M White, Raul E Angulo

Prompt cusps are the densest quasi-equilibrium dark matter objects; one forms at the instant of collapse within every isolated peak of the initial cosmological density field. They have power-law density profiles, $\rho \propto r^{-1.5}$ with central
