Exploring non-equilibrium effects in sequential freeze-in
Shiuli Chatterjee, Andrzej Hryczuk
Freeze-in of multi-component dark sectors is governed not only by the interaction with the thermal plasma, but also by their internal dynamics. Full thermalisation within the dark…
Conversions in two-component dark sectors: a phase space level analysis
Shiuli Chatterjee, Andrzej Hryczuk
Conversions between the states in the dark sector affect not only their number densities but also their momentum distributions. In this work we study a phenomenologically motivated…
Faint light of old neutron stars and detectability at the James Webb Space Telescope
Shiuli Chatterjee, Raghuveer Garani, Rajeev Kumar Jain +3
Isolated ideal neutron stars (NS) of age yrs exhaust thermal and rotational energies and cool down to temperatures below K. Accretion of particle dark ma…
Explorations of pseudo-Dirac dark matter having keV splittings and interacting via transition electric and magnetic dipole moments
Shiuli Chatterjee, Ranjan Laha
We study a minimal model of pseudo-Dirac dark matter, interacting through transition electric and magnetic dipole moments. Motivated by the fact that xenon experiments can detect e…
Freezing In with Lepton Flavored Fermions
Giancarlo D'Ambrosio, Shiuli Chatterjee, Ranjan Laha +1
Dark, chiral fermions carrying lepton flavor quantum numbers are natural candidates for freeze-in. Small couplings with the Standard Model fermions of the order of lepton Yukawas a…
