Tuning the violins: dark sector phase transition models for the PTA signal
Torsten Bringmann, Thomas Konstandin, Jonas Matuszak +2
First-order phase transitions in a dark sector have been invoked as an intriguing possibility to explain the observed stochastic gravitational wave background at nanohertz frequenc…

Sub-GeV dark matter and nano-Hertz gravitational waves from a classically conformal dark sector
Sowmiya Balan, Torsten Bringmann, Felix Kahlhoefer +2
Strong first-order phase transitions in a dark sector offer a compelling explanation for the stochastic gravitational wave background in the nano-Hertz range recently detected by p…

Dark Matter Line Searches with the Cherenkov Telescope Array
S. Abe, J. Abhir, A. Abhishek +562
Monochromatic gamma-ray signals constitute a potential smoking gun signature for annihilating or decaying dark matter particles that could relatively easily be distinguished from a…
