Primordial Asymmetries, Primordial Equation of State & Primordial Black Holes
Maël Gonin, Julien Froustey, Albert Escrivà +3
We study the thermal history of the primordial Universe in presence of non-zero lepton and baryon asymmetries. Considering different scenarios, we determine the equation of state (…
What could an emerging Big Bang Nucleosynthesis discrepancy be hinting at?
Vivian Poulin, Julien Froustey, Cyril Pitrou +1
The latest measurement of the primordial deuterium abundance is in tension with several state-of-the-art predictions of standard Big Bang nucleosynthesis (BBN), when usi…
Neutrino helicity oscillations in astrophysical environments: a many-body approach
Yiheng Xu, Julien Froustey, George M. Fuller +2
Neutrino rest mass enables left-handed states to "flip" to right-handed states and vice versa. In-medium effects can enhance the probability for such spin-flip. We demonstrate that…
Neutrino transport and flavor instabilities in a post-merger disk
Erick Urquilla, Swapnil Shankar, Debraj Kundu +6
Neutron star mergers are multimessenger sources whose dynamics and signals depend critically on neutrinos and their flavor transformations. We investigate whether fast and collisio…
Fifty shades of grayness: parametrizations of spectral distortions and applications in cosmology
Gabriela Barenboim, Julien Froustey, Cyril Pitrou +1
Thermal distribution functions can only be of the Fermi-Dirac or Bose-Einstein types, whereas distorted spectra encompass any possible deviations from these shapes. It is fruitful…
Neutrino flavor instabilities in neutron star mergers with moment transport: Slow, fast, and collisional modes
Julien Froustey, Francois Foucart, Christian Hall +5
Determining where, when, and how neutrino flavor oscillations must be included in large-scale simulations of hot and dense astrophysical environments is an enduring challenge that…
