Sagittarius as a plausible source candidate for PeV neutrinos
Sabyasachi Ray, Rajat K. Dey
We propose that the recently observed diffuse neutrinos by IceCube with energies above 1 PeV might have originated from Sagittarius located in the galactic dis…
Diffuse flux of PeV neutrinos from centrifugally accelerated protons in active galactic nuclei
Rajat K. Dey, Animesh Basak, Sabyasachi Ray
Evidence for high-energy astrophysical PeV neutrinos has been found in the IceCube experiment from an analysis with a 7.5 year (2010 - 2017) data. Active galactic nuclei (AGN) are…
Newly born extragalactic millisecond pulsars as efficient emitters of PeV neutrinos
Rajat K. Dey, Animesh Basak, Sabyasachi Ray +1
The origins of the diffuse flux of cosmogenic PeV neutrinos detected in the IceCube experiment during 2010 - 2017 remain unidentified. A population of extragalactic newly born fast…
Searching for correlations of geomagnetic activities with high-energy EAS muons
Rajat K. Dey, Sabyasachi Ray, Sandip Dam
The paper aims to explore the asymmetry of the muon content of non-vertical and very high energy Monte Carlo showers due to the influence of Earth's geomagnetic field. Simulations…
Determination of the mass and energy of primary cosmic rays above 100 TeV
R. K. Dey, S. Dam, S. Ray +2
This analysis aims to determine the mass composition and energy of cosmic rays at energies above 100 TeV based on the lateral distribution of extensive air showers. Here, we propos…
Searching for PeV neutrinos from photomeson interactions in magnetars
Rajat K. Dey, Sabyasachi Ray, Sandip Dam
In this paper we estimate the flux of PeV neutrinos and gamma-rays from magnetar polar caps, assuming that ions/protons are injected, and accelerated in these regions and interact…
