Luminosity Signatures of Dark Sector Particles from Black Hole Evaporation in Neutron Stars
Ioannis Dalianis, Anastasios Irakleous
Microscopic black holes may form at the centers of neutron stars through the accumulation and collapse of dark matter. While Standard Model particles produced by Hawking evaporatio…
High-Energy Neutrinos from Black Hole Evaporation in Neutron Stars
Ioannis Dalianis
We investigate the production of high-energy neutrinos from microscopic black holes formed through the gravitational collapse of asymmetric dark matter accumulated inside neutron s…
Is Gauge Mediation in the Swampland?
Ioannis Dalianis, Fotis Farakos, Alex Kehagias
We note that the typical gauge mediation of supersymmetry breaking is in tension with the global limit of the festina lente swampland bound. The alternatives are mediation/breaking…
Freeze-in baryogenesis and early matter domination
Ioannis Dalianis, Andreas Goudelis, Dimitrios Karamitros +2
The freeze-in mechanism has been shown to allow the simultaneous generation of cosmic dark matter and a viable matter-antimatter asymmetry in the universe. When the underlying inte…
Reheating in runaway inflation models via the evaporation of mini primordial black holes
Ioannis Dalianis, George P. Kodaxis
We investigate the cosmology of mini Primordial Black Holes (PBHs) produced by large density perturbations that collapse during a stiff fluid domination phase. Such a phase can be…
On the Vacuum Structure of the Conformal Supergravity
Ioannis Dalianis, Alex Kehagias, Ioannis Taskas +1
We consider conformal supergravity with an arbitrary holomorphic function of the complex scalar which parametrizes the coset. Assuming non-vanishing…
