Constraints on ultracompact minihalos from extragalactic γ-ray background
Yupeng Yang, Lei Feng, Xiaoyuan Huang +3
It has been proposed that ultracompact minihalos (UCMHs) might be formed in earlier epoch. If dark matter consists of Weakly Interacting Massive Particles (WIMPs), UCMHs can be tre…
Galaxy Clusters and Gamma-Ray Lines: Probing Gravitino Dark Matter with the Fermi LAT
Xiaoyuan Huang, Gilles Vertongen, Christoph Weniger
If dark matter particles are not perfectly stable, their decay products might be seen in the cosmic-ray fluxes. A natural candidate for decaying dark matter is the gravitino in R-p…
Probing Dark Matter Decay and Annihilation with Fermi LAT Observations of Nearby Galaxy Clusters
Xiaoyuan Huang, Gilles Vertongen, Christoph Weniger
Galaxy clusters are promising targets for indirect dark matter searches. Gamma-ray signatures from the decay or annihilation of dark matter particles inside these clusters could be…
New Constraints on Primordial Minihalo Abundance Using Cosmic Microwave Background Observations
Yupeng Yang, Xiaoyuan Huang, Xuelei Chen +1
It was proposed that the massive compact halo objects (MCHOs) would be produced during an earlier epoch of cosmology if the density perturbations are between and…
