Chandrasekhar limit for rotating quark stars
Ashadul Halder, Shibaji Banerjee, Sanjay K. Ghosh +1
The limiting mass is a significant characteristic for compact exotic stars. In the case of quark stars, the limiting mass can be expressed in terms of fundamental constants and the…
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…
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…
Intensification of Gravitational Wave Field Near Compact Star
Ashadul Halder, Shibaji Banerjee, Debasish Majumdar
The gravitational waves (GWs) has been a topic of interest for its versatile capabilities of probing several aspects of cosmology and early Universe. Gravitational lensing enhances…
Speeding up of Binary Merger Due to "Apparent" Gravitational Wave Emissions
Shibaji Banerjee, Ashadul Halder, Sanjay K. Ghosh +2
Gravitational waves from binary black hole pairs have emerged as an important observational tool in current times. The energy of the BH - BH binary pair is radiated in the form of…
