Non-Cold Dark Matter from Memory-Burdened Primordial Black Holes
Valentin Thoss, Laura Lopez-Honorez, Florian Kühnel +1
Non-cold dark matter particles can arise from the evaporation of primordial black holes (PBHs). In this paper, we further investigate how the memory-burden effect, which delays the…
Inferring the mass and size of 3I/ATLAS from its non-gravitational acceleration
Valentin Thoss, Abraham Loeb, Andreas Burkert
Observations of the interstellar object 3I/ATLAS have revealed a strong production of gas and dust near perihelion, together with rapid brightening. The outgassing from the nucleus…
Detecting dark objects in the Solar System with Gravitational Wave observatories
Valentin Thoss, Abraham Loeb
Dark objects streaming into the solar system can be probed using gravitational wave (GW) experiments through the perturbations that they would induce on the detector test masses. I…
New bounds on Memory Burdened Primordial Black Holes from Big Bang Nucleosynthesis
Arnab Chaudhuri, Kazunori Kohri, Valentin Thoss
Primordial black holes (PBHs) with masses below are typically assumed to have negligible cosmological impact due to their rapid evaporation via Hawking radiation. Ho…
Primordial Black Holes in the Solar System
Valentin Thoss, Andreas Burkert
If primordial black holes (PBHs) of asteroidal mass make up the entire dark matter, they could be detectable through their gravitational influence in the solar system. In this work…
