Gravitational Wave Emissions from First Order Phase Transitions with Two Component FIMP Dark Matter
Madhurima Pandey, Avik Paul
We explore the emissions of the Gravitational Waves (GWs) from a strong first-order ekectroweak phase transition. To this end, a dark matter model has been investigated in Feebly I…
Addressing -ray emissions from dark matter annihilations in 45 milky way satellite galaxies and in extragalactic sources with particle dark matter models
Ashadul Halder, Shibaji Banerjee, Madhurima Pandey +1
The mass to luminosity ratio of the dwarf satellite galaxies in the Milky Way suggests that these dwarf galaxies may contain substantial dark matter. The dark matter at the dense r…
IceCube PeV Neutrino Events from the Decay of Superheavy Dark Matter;an Analysis
Madhurima Pandey, Debasish Majumdar, Ashadul Halder
Considering the ultrahigh energy (UHE) neutrino events reported by IceCube in the PeV regime to have originated from the decay of superheavy dark matter, the IceCube UHE neutrino e…
Implications of a proton blazar inspired model on correlated observations of neutrinos with gamma-ray flaring blazars
Prabir Banik, Arunava Bhadra, Madhurima Pandey +1
Recent detection of the neutrino events IceCube-170922A, 13 muon-neutrino events observed in 2014-2015 and IceCube-141209A by IceCube observatory from the Blazars, namely TXS 0506+…
Mass and Life Time of Heavy Dark Matter Decaying into IceCube PeV Neutrinos
Madhurima Pandey, Debasish Majumdar, Ashadul Halder +1
Considering that the ultrahigh energy (UHE) upgoing muon neutrino events around the PeV energy region observed by the IceCube are due to the decay of super heavy dark matter to neu…
Effects of Violation of Equivalence Principle on UHE Neutrinos at IceCube in 4 Flavour Scenario
Madhurima Pandey
If weak equivalence principle is violated then different types of neutrinos would couple differently with gravity and that may produce a gravity induced oscillation for the neutrin…
