Estimating f_NL and g_NL from Massive High-Redshift Galaxy Clusters
Kari Enqvist, Shaun Hotchkiss, Olli Taanila
There are observations of 15 high-redshift massive galaxy clusters, which have an extremely small probability with a purely Gaussian initial curvature perturbation. Here we revisit…
The TeV-mass curvaton
Kari Enqvist, Anupam Mazumdar, Olli Taanila
We consider the constraints for a curvaton with mass m ~ 1 TeV and show that they are not consistent with a purely quadratic potential. Even if the curvaton self-interactions were…
Fast Electroweak Symmetry Breaking and Cold Electroweak Baryogenesis
Kari Enqvist, Philip Stephens, Olli Taanila +1
We construct a model for delayed electroweak symmetry breaking that takes place in a cold Universe with T<<100 GeV and which proceeds by a fast quench rather than by a conventional…
