The Sound of Dark Sectors in Pulsar Timing Arrays
Amitayus Banik, Yanou Cui, Yu-Dai Tsai +1
A phase transition in the dark sector (DS) presents a promising explanation for the stochastic gravitational wave (GW) signals detected in recent observations by Pulsar Timing Arra…
A cosmological case study of a tower of warm dark matter states: naturalness
Saurabh Bansal, Subhajit Ghosh, Matthew Low +1
In this work, we study the cosmological effects of a tower of warm dark matter states on the cosmic microwave background (CMB) and on large-scale structure (LSS). For concreteness,…
Dark Matter-Radiation Scattering Enhances CMB Phase Shift through Dark Matter-loading
Subhajit Ghosh, Daven Wei Ren Ho, Yuhsin Tsai
A phase shift in the acoustic oscillations of CMB spectra is a characteristic signature for the presence of non-photon radiation propagating differently from photons, even when the…
