Observational constraints on supermassive dark stars
Erik Zackrisson, Pat Scott, Claes-Erik Rydberg +6
Some of the first stars could be cooler and more massive than standard stellar models would suggest, due to the effects of dark matter annihilation in their cores. It has recently…
The WIMP capture process for dark stars in the early universe
Sofia Sivertsson, Paolo Gondolo
The first stars to form in the universe may have been dark stars, powered by dark matter annihilation instead of nuclear fusion. The initial amount of dark matter gathered by the s…
Finding high-redshift dark stars with the James Webb Space Telescope
Erik Zackrisson, Pat Scott, Claes-Erik Rydberg +7
The first stars in the history of the Universe are likely to form in the dense central regions of 10^5-10^6 Msolar cold dark matter halos at z=10-50. The annihilation of dark matte…
Gamma rays from ultracompact primordial dark matter minihalos
Pat Scott, Sofia Sivertsson
Ultracompact minihalos have recently been proposed as a new class of dark matter structure. These minihalos would be produced by phase transitions in the early Universe or features…
Accurate calculations of the WIMP halo around the Sun and prospects for gamma ray detection
Sofia Sivertsson, Joakim Edsjö
Weakly interacting massive particles (WIMPs) can be captured by heavenly objects, like the Sun. Under the process of being captured by the Sun, they will build up a population of W…
