Isocurvature Induced Gravitational Waves at Pulsar Timing Arrays
Yi-Fu Cai, Peizhi Du, Jiahang Zhong
Gravitational waves (GWs) are powerful probes of new physics in the early Universe. In particular, GWs induced by primordial isocurvature perturbations encode information of novel…
Cosmological Constraints on Secluded Dark Radiation
Jae Hyeok Chang, Peizhi Du, Subhajit Ghosh +1
Dark radiation (DR) is ubiquitous in physics beyond the Standard Model (SM), and its interactions with the SM and dark matter (DM) lead to a variety of interesting effects on cosmo…
General Constraints on Isocurvature from the CMB and Ly- Forest
Matthew R. Buckley, Peizhi Du, Nicolas Fernandez +1
Current cosmological data are well-described by the Lambda-Cold Dark Matter (CDM) model, which assumes adiabatic initial conditions for the primordial density perturbations. Thi…
Dark Radiation Isocurvature from Cosmological Phase Transitions
Matthew R. Buckley, Peizhi Du, Nicolas Fernandez +1
Cosmological first order phase transitions are typically associated with physics beyond the Standard Model, and thus of great theoretical and observational interest. Models of phas…
