Multimessenger Constraints on Supermassive Dark Stars and Their Black Hole Remnants
Marco Manno, Thomas Schwemberger, Volodymyr Takhistov
Dark matter (DM) annihilation can power the first generation of stars as long lived dark stars (DSs) that grow to supermassive scales and event…
Clash of the Titans: ultra-high energy KM3NeT event versus IceCube data
Shirley Weishi Li, Pedro Machado, Daniel Naredo-Tuero +1
KM3NeT has reported the detection of a remarkably high-energy through-going muon. Lighting up about a third of the detector, this muon likely originated from a neutrino exceeding 1…
Diffuse Neutrino Signals from Dark Stars Seeding Super-Massive Black Holes
Thomas Schwemberger, Volodymyr Takhistov
Dark stars (DSs) -- first stars powered by dark-matter (DM) heating rather than fusion -- could form in the early Universe. They can grow to masses and col…
Direct detection of primordial black hole relics as dark matter
Benjamin V. Lehmann, Christian Johnson, Stefano Profumo +1
If dark matter is composed of primordial black holes, such black holes can span an enormous range of masses. A variety of observational constraints exist on massive black holes, an…
