Directly Probing Neutrino Interactions through CMB Phase Shift Measurements
Gabriele Montefalcone, Subhajit Ghosh, Kimberly K. Boddy +2
Perturbations in the cosmic neutrino background produce a characteristic phase shift in the acoustic oscillations imprinted in the anisotropies of the cosmic microwave background (…
Echoes of Self-Interacting Dark Matter from Binary Black Hole Mergers
Amitayus Banik, Jeong Han Kim, Jun Seung Pi +1
Dark matter (DM) environments around black holes (BHs) can influence their mergers through dynamical friction, causing gravitational wave (GW) dephasing during the inspiral phase.…
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…
