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…

Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory
K. Abe, S. Abe, J. Abhir +491
The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…

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…
