Dark Matter Signatures in the Anisotropic Radio Sky
Le Zhang, Guenter Sigl
We calculate intensity and angular power spectrum of the cosmological background of synchrotron emission from cold dark matter annihilations into electron positron pairs. We compar…

Contraints on radiative dark-matter decay from the cosmic microwave background
Le Zhang, Xuelei Chen, Marc Kamionkowski +2
If dark matter decays to electromagnetically-interacting particles, it can inject energy into the baryonic gas and thus affect the processes of recombination and reionization. This…

The impacts of dark matter particle annihilation on recombination and the anisotropies of the cosmic microwave background
Le Zhang, Xuelei Chen, Yi-An Lei +1
The recombination history of the Universe provides a useful tool for constraining the annihilation of dark matter particles. Even a small fraction of dark matter particles annihila…
