Tachyonic particle production in strongly supercooled phase transitions
Mateusz Kulejewski, Bogumila Swiezewska, Jorinde van de Vis
In strongly supercooled cosmological phase transitions, which generically lead to strong, observable gravitational-wave backgrounds, the scalar field typically transitions to a val…

Frequency shift and viewing direction variations in gravitational lensing
Mikołaj Korzyński, Mateusz Kulejewski
In a gravitational lensing system, the relative transverse velocities of the lens, source, and observer induce a frequency shift in the observed radiation. While this shift is typi…
