We consider a scenario where the 6×6 neutrino... Read More about From Dirac to Majorana: The cosmic neutrino background capture rate in the minimally extended Standard Model.

Testing high scale supersymmetry via second order gravitational waves (2023)
Journal Article
Flores, M. M., Kusenko, A., Pearce, L., Perez-Gonzalez, Y. F., & White, G. (2023). Testing high scale supersymmetry via second order gravitational waves. Physical Review D, 108, Article 123002. https://doi.org/10.1103/PhysRevD.108.123002

Supersymmetry predicts multiple flat directions, some of which carry a net baryon or lepton number. Condensates in such directions form during inflation and later fragment into Q balls, which can become the building blocks of primordial black holes....

Identifying spin properties of evaporating black holes through asymmetric neutrino and photon emission (2023)
Journal Article

Kerr black holes radiate neutrinos in an asymmetric pattern, preferentially in the lower hemisphere relative to the black hole’s rotation axis, while antineutrinos are predominantly produced in the upper hemisphere. Leveraging this asymmetric emissio... Read More about Identifying spin properties of evaporating black holes through asymmetric neutrino and photon emission.

JUNO as a probe of the pseudo-Dirac nature using solar neutrinos (2023)
Journal Article

It remains a possibility that neutrinos are pseudo-Dirac states, such that a generation is composed of two maximally mixed Majorana neutrinos separated by a very small mass difference. We explore the physics potential of the JUNO experiment in constr... Read More about JUNO as a probe of the pseudo-Dirac nature using solar neutrinos.

Evaporation of primordial black holes in the early Universe: Mass and spin distributions (2023)
Journal Article

Many cosmological phenomena lead to the production of primordial black holes in the early Universe. These phenomena often create a population of black holes with extended mass and spin distributions. As these black holes evaporate via Hawking radiati... Read More about Evaporation of primordial black holes in the early Universe: Mass and spin distributions.

Redshift effects in particle production from Kerr primordial black holes (2022)

When rotating primordial black holes evaporate via Hawking radiation, their rotational energy and mass are dissipated with different dynamics. We investigate the effect of these dynamics on the production of dark radiation—in the form of hot graviton...
