Enhanced Matter Power Spectrum from Axion Kination after Big Bang Nucleosynthesis
Raymond T. Co, Nicolas Fernandez, Akshay Ghalsasi +2
Despite stringent constraints from Big Bang Nucleosynthesis (BBN) and cosmic microwave background (CMB) observations, it is still possible for well-motivated particle physics model…
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…
Observational evidence for cosmological coupling of black holes and its implications for an astrophysical source of dark energy
Duncan Farrah, Kevin S. Croker, Gregory Tarlé +16
Observations have found black holes spanning ten orders of magnitude in mass across most of cosmic history. The Kerr black hole solution is however provisional as its behavior at i…
Complementary Constraints on Light Dark Matter from Heavy Quarkonium Decays
Nicolas Fernandez, Jason Kumar, Ilsoo Seong +1
We investigate constraints on the properties of light dark matter which can be obtained from analysis of invisible quarkonium decays at high intensity electron-positron colliders i…
