Galaxy Clusters in Dark Matter Window: The Case of the Shapley Supercluster
UniverseDark matter dominates the matter content of the Universe, yet its particle nature remains elusive. Among the promising multi-messenger astronomy dark matter candidates are weakly interacting massive particles and superheavy dark matter, both of which may

Scale-Independent Relations Between Neutrino Mass Parameters
UniverseTheories of flavor operate at various scales. Recently it has been pointed out that in the context of modular flavor symmetries, certain combinations of observables are highly constrained, or even uniquely fixed, by modular invariance and holomorphicity.

Hillas meets Eddington: The case for blazars as ultra-high-energy neutrino sources
Astronomy & AstrophysicsContext. Jetted active galactic nuclei aligned with our line of sight known as blazars are promising high-energy neutrino source candidates. However, leptohadronic models face challenges in describing neutrino emission within a viable energy budget and ...

Gravitational Wave Signatures of Warm Dark Matter in the Gauge Extensions of the Standard Model
UniverseWe studied the left-right symmetric extension of the standard model (LRSM), featuring a TeV-scale, right-handed (RH) gauge boson WR and three RH neutrinos. This setup naturally realizes the type-II seesaw mechanism for active neutrino masses.

Supernova Neutrino Neutrino Astronomy
, 2018 Modern neutrino facilities will be able to detect a large number of neutrinos from the next Galactic supernova. We investigate the viability of the triangulation method to locate a core-collapse supernova by employing the neutrino arrival time differences at various detectors.
