Can we detect Hot or Cold spots in the CMB with Minkowski Functionals?
Eugene A. Lim, Dennis Simon
In this paper, we investigate the utility of Minkowski Functionals as a probe of cold/hot disk-like structures in the CMB. In order to construct an accurate estimator, we resolve a…
Cosmological first-order phase transitions beyond the standard inflationary scenario
Aleksandar Rakic, Dennis Simon, Julian Adamek +1
Motivated by cosmological first-order phase transitions we examine the nucleation and evolution of vacuum bubbles in non-vacuum environments. Non-standard backgrounds can be releva…
On the fate of vacuum bubbles on matter backgrounds
Aleksandar Rakic, Dennis Simon, Julian Adamek +1
In this letter we discuss cosmological first order phase transitions with de Sitter bubbles nucleating on (inhomogeneous) matter backgrounds. The de Sitter bubble can be a toy mode…
Tunneling and propagation of vacuum bubbles on dynamical backgrounds
Dennis Simon, Julian Adamek, Aleksandar Rakic +1
In the context of bubble universes produced by a first-order phase transition with large nucleation rates compared to the inverse dynamical time scale of the parent bubble, we exte…
