217. Spatial cross-correlation study of IceCube neutrino alerts and high energy gamma-ray cataloguesProf. Pratik Majumdar (Saha Institute of Nuclear Physics)
Since 2019, the IceCube Neutrino Observatory has issued real-time neutrino alerts via the General Coordinates Network (GCN), following the successful identification of a high-energy neutrino event, IceCube-170922A, in association with a multiwavelength flare from the blazar TXS~0506+056. Although many high-energy neutrinos have been observed since then, their astrophysical counterparts remain...

With the help of a full Euler-like block parametrization of the flavor structure for the canonical seesaw mechanism, we present the first general and explicit analytical calculations of the light neutrino mass-squared differences, flavor mixing angles and leptonic CP violation responsible for the primary behaviors of neutrino oscillations. Such model-independent results will pave the way for...

Mergers of neutron stars offer a unique probe of ultra-dense nuclear matter, far beyond the reach of terrestrial experiments. However, fully exploiting the multimessenger nature of these events, combining gravitational waves, electromagnetic counterparts, and dense matter physics, poses a major computational challenge. This burden will become even more pressing with next-generation...

The similarity between dark matter and baryon energy densities suggests the existence of a dark QCD sector analogous to the visible QCD sector. Moreover, small-scale structure issues can be addressed by self-interacting dark matter with a cross section comparable to that of QCD. These two observations together hint at a GeV-scale dark QCD sector. In this talk, I will present how a Chiral...
