Leptogenesis and Planck-scale black hole remnants in a Pati-Salam cosmology
Arnab Chaudhuri, Erdenebulgan Lkhagvadorj, Satyabrata Mahapatra
We study leptogenesis and Planck-scale remnant dark matter from primordial black hole (PBH) evaporation in a minimal Pati-Salam cosmology, with the gauge symmetry broken before inf…
Scalar Portal Verifiable Light Dark Matter and Correlated Gravitational Wave Signatures
Ki-Young Choi, Erdenebulgan Lkhagvadorj, Satyabrata Mahapatra
The lack of signals in direct detection experiments has placed the canonical Weakly Interacting Massive Particle (WIMP) paradigm under severe tension, motivating a shift toward the…
Cosmological Origin of the KM3-230213A event and associated Gravitational Waves
Ki-Young Choi, Erdenebulgan Lkhagvadorj, Satyabrata Mahapatra
We propose a novel cosmological scenario to explain the exceptional KM3-230213A neutrino event reported at an energy scale of ~PeV by the KM3NeT collaboration, al…
Gravitational Wave Sourced by Decay of Massive Particle from Primordial Black Hole evaporation
Ki-Young Choi, Erdenebulgan Lkhagvadorj, Satyabrata Mahapatra
In this article, we investigate the stochastic gravitational waves (GWs) spectrum, resulting from the emission of gravitons through bremsstrahlung, in the decay of particles produc…
Non-thermal WIMPy Baryogenesis with Primordial Black Hole
Ki-Young Choi, Jongkuk Kim, Erdenebulgan Lkhagvadorj
We consider the possibility that the weakly interacting massive particles produced from the evaporation of primordial black hole can explain both the relic density of dark matter a…
Probing sterile neutrino dark matter in the PTOLEMY-like experiment
Ki-Young Choi, Erdenebulgan Lkhagvadorj, Seong Moon Yoo
We study the prospect to detect the cosmic background of sterile neutrinos in the Tritium -decay, such as PTOLEMY-like experiments. The sterile neutrino with mass between 1 eV -…
