Gravitational waves and tadpole resummation: Efficient and easy convergence of finite temperature QFT
David Curtin, Jyotirmoy Roy, Graham White
We demonstrate analytically and numerically that "optimized partial dressing" (OPD) thermal mass resummation, which uses gap equation solutions inserted into the tadpole, efficient…

Did we hear the sound of the Universe boiling? Analysis using the full fluid velocity profiles and NANOGrav 15-year data
Tathagata Ghosh, Anish Ghoshal, Huai-Ke Guo +5
In this paper, we analyse sound waves arising from a cosmic phase transition where the full velocity profile is taken into account as an explanation for the gravitational wave spec…
