Hidden Inflaton Dark Matter
Juan P. Beltrán Almeida, Nicolás Bernal, Javier Rubio +1
If cosmic inflation was driven by an electrically neutral scalar field stable on cosmological time scales, the field necessarily constitutes all or part of dark matter (DM). We stu…
Scalar singlet dark matter in non-standard cosmologies
Nicolás Bernal, Catarina Cosme, Tommi Tenkanen +1
We study production of dark matter (DM) in models with a non-standard expansion history. We consider both freeze-out and freeze-in mechanisms for producing the observed DM abundanc…
Phenomenology of Self-Interacting Dark Matter in a Matter-Dominated Universe
Nicolás Bernal, Catarina Cosme, Tommi Tenkanen
We study production of self-interacting dark matter (DM) during an early matter-dominated phase. As a benchmark scenario, we consider a model where the DM consists of singlet scala…
Prospects for indirect detection of frozen-in dark matter
Matti Heikinheimo, Tommi Tenkanen, Kimmo Tuominen
We study observational consequences arising from dark matter (DM) of non-thermal origin, produced by dark freeze-out from a hidden sector heat bath. We assume this heat bath was po…
The Dawn of FIMP Dark Matter: A Review of Models and Constraints
Nicolás Bernal, Matti Heikinheimo, Tommi Tenkanen +2
We present an overview of scenarios where the observed Dark Matter (DM) abundance consists of Feebly Interacting Massive Particles (FIMPs), produced non-thermally by the so-called…
WIMP miracle of the second kind
Matti Heikinheimo, Tommi Tenkanen, Kimmo Tuominen
We study dark matter production in scenarios where a scale invariant hidden sector interacts with the Standard Model degrees of freedom via a Higgs portal . If the…
