FLUMEN: Neural Emulator of an Advanced Stochastic Weak Lensing Model
Galymzhan Baltabay, Ville Vaskonen
Weak gravitational lensing by intervening structure magnifies distant sources and induces scatter in their luminosity distances. We develop an improved stochastic model for the dis…

Axion Misalignment Across First-Order Phase Transitions
Galymzhan Baltabay, Francesco D'Eramo, Ville Vaskonen
When the axion mass is generated during a first-order phase transition and becomes non-vanishing only inside expanding true-vacuum bubbles, the standard picture of misalignment pro…
