Radiation Exposure from the Dark
Florian Niedermann, Martin S. Sloth
We explore the possibility that exotic forms of dark matter could expose humans on Earth or on prolonged space travel to a significant radiation dose. The radiation exposure from d…
New Early Dark Energy as a solution to the and tensions
Florian Niedermann, Martin S. Sloth
New Early Dark Energy introduces a new phase of dark energy that decays in a fast-triggered phase transition around matter-radiation equality. The presence of a trigger mechanism s…
Hot New Early Dark Energy
Florian Niedermann, Martin S. Sloth
New early dark energy (NEDE) makes the cosmic microwave background consistent with a higher value of the Hubble constant inferred from supernovae observations. It is an improvement…
Hot New Early Dark Energy: Towards a Unified Dark Sector of Neutrinos, Dark Energy and Dark Matter
Florian Niedermann, Martin S. Sloth
Hot new early dark energy describes a supercooled, first-order phase transition that takes place at sub-eV temperatures in the dark sector. It lowers the sound horizon, which provi…
Gravitational Atoms
Niklas G. Nielsen, Andrea Palessandro, Martin S. Sloth
Particles in a yet unexplored dark sector with sufficiently large mass and small gauge coupling may form purely gravitational atoms (quantum gravitational bound states) with a rich…
Charged Planckian Interacting Dark Matter
Mathias Garny, Andrea Palessandro, McCullen Sandora +1
A minimal model of Cold Dark Matter (CDM) is a very massive particle with only gravitational interactions, also called Planckian Interacting Dark Matter (PIDM). Here we consider an…
