Wash-In Leptogenesis
Valerie Domcke, Kohei Kamada, Kyohei Mukaida +2
We present a leptogenesis mechanism based on the standard type-I seesaw model that successfully operates at right-handed-neutrino masses as low as a few 100 TeV. This mechanism, wh…
Model-independent energy budget for LISA
Felix Giese, Thomas Konstandin, Kai Schmitz +1
We provide an easy method to obtain the kinetic energy fraction in gravitational waves, generated during a cosmological first-order phase transition, as a function of only the wall…
From NANOGrav to LIGO with metastable cosmic strings
Wilfried Buchmuller, Valerie Domcke, Kai Schmitz
We interpret the recent NANOGrav results in terms of a stochastic gravitational wave background from metastable cosmic strings. The observed amplitude of a stochastic signal can be…
Has NANOGrav found first evidence for cosmic strings?
Simone Blasi, Vedran Brdar, Kai Schmitz
The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) has recently reported strong evidence for a stochastic common-spectrum process affecting the pulsar timi…
Leptogenesis and low-energy CP violation in a type-II-dominated left-right seesaw model
Thomas Rink, Werner Rodejohann, Kai Schmitz
We consider leptogenesis in a left-right-symmetric seesaw scenario in which neutrino mass generation and leptogenesis are dominated by the type-II seesaw term. Motivated by grand u…
LISA Sensitivity to Gravitational Waves from Sound Waves
Kai Schmitz
Gravitational waves (GWs) produced by sound waves in the primordial plasma during a strong first-order phase transition in the early Universe are going to be a main target of the u…
