Echo of the Dark: gravitational waves from dark SU(3) Yang-Mills theory

Enrico Morgante, Nicklas Ramberg, Pedro Schwaller

We analyze the phase transition in improved holographic QCD to obtain an estimate of the gravitational wave signal emitted in the confinement transition of a pure SU(3) Yang-Mills…

One $μ$ to rule them all: CMB spectral distortions can probe domain walls, cosmic strings and low scale phase transitions

Nicklas Ramberg, Wolfram Ratzinger, Pedro Schwaller

We present a new probe of purely gravitationally coupled sectors with large anisotropies. These anisotropies are damped via gravitational interactions with the baryon-photon fluid,…
