Gesturing in the early universities.

Dynamis (Granada, Spain), 2000
Research into the oral and literary traditions of scholastic education usually emphasizes the significance of the world in late medieval pedagogy. This paper suggests that coded hand signals provided early university scholars with an important non-verbal means of communication too.

Building the First Galaxies—Chapter 2. Starbursts Dominate the Star Formation Histories of 6 < z < 12 Galaxies

The Astrophysical Journal
We use SEDz* —a code designed to chart the star formation histories (SFHs) of 6 < z < 12 galaxies—to analyze the spectral energy distributions (SEDs) of 894 galaxies with deep JWST/NIRCam imaging by JADES in the GOODS-S field.

Thermalization effects on the dynamics of growing vacuum bubbles

Journal of High Energy Physics
We study the evolution of growing vacuum bubbles. The bubble walls interact with the surrounding fluid and may, consequently, reach a terminal velocity.

What happens when supercooling is terminated by curvature flipping of the effective potential?

Journal of High Energy Physics
We explore the nature of a certain type of supercooled phase transition, where the supercooling is guaranteed to end due to the curvature of the finite-temperature effective potential at the origin experiencing a sign flip at some temperature.

Bubble-wall velocity in local thermal equilibrium: hydrodynamical simulations vs analytical treatment

Journal of High Energy Physics
We perform real-time hydrodynamical simulations of the growth of bubbles formed during cosmological first-order phase transitions under the assumption of local thermal equilibrium.
