The IceCube Neutrino Observatory has established the existence of a high-energy all-sky
neutrino flux of astrophysical origin. This discovery was made using events interacting within …

The IceCube observatory located at the South Pole is a cubic-kilometre optical Cherenkov
telescope primarily designed for the detection of high-energy astrophysical neutrinos …

Astrophysical neutrinos are excellent probes of astroparticle physics and high-energy
physics. With energies far beyond solar, supernovae, atmospheric, and accelerator …

We study the detection prospects of relatively light charged scalars in radiative Majorana
neutrino mass models, such as the Zee model and its variants using scalar leptoquarks, at …

The discovery of diffuse sub-PeV gamma-rays by the Tibet AS γ Collaboration promises to
revolutionize our understanding of the high-energy astrophysical universe. It has been …

We systematically study the allowed parameter space for the flavor composition of
astrophysical neutrinos measured at Earth, including beyond the Standard Model theories at …

We discuss a simple non-supersymmetric model based on the electroweak gauge group SU
(2) L× SU (2)'× U (1) B–L where the lightest of the right-handed neutrinos, which are part of …

In view of the IceCube's 6-year high-energy starting events (HESE) sample, we revisit the
possibility that the updated data may be better explained by a combination of neutrino fluxes …

We systematically investigate new physics scenarios that can modify the interactions
between neutrinos and matter at upcoming tau neutrino telescopes, which will test neutrino …

The ANITA balloon experiment has observed two EeV-energy, up-going events originating
from well below the horizon. This is puzzling because (i) no standard model (SM) particle is …
