Freeze-in leptogenesis with sterile neutrino self-interactions
Maria Dias Astros, Stefan Vogl
Sterile neutrinos are a simple yet compelling addition to the Standard Model. For right-handed neutrinos with masses below the electroweak scale, leptogenesis can proceed through C…

Minimal Inert Doublet Benchmark for Dark Matter and the Baryon Asymmetry
María Dias Astros, Sven Fabian, Florian Goertz
In this article we discuss a minimal extension of the Inert Doublet Model (IDM) with an effective -violating operator, involving the inert Higgs and weak gauge bosons, th…

Boosting the production of sterile neutrino dark matter with self-interactions
Maria Dias Astros, Stefan Vogl
Sterile neutrinos are well-motivated and simple dark matter (DM) candidates. However, sterile neutrino DM produced through oscillations by the Dodelson-Widrow mechanism is excluded…
