Description

Examining cosmic rays, gamma rays, neutrinos, and gravitational waves, this track focuses on the interplay between particle physics and astrophysics. Discussions will highlight multimessenger astronomy, cosmic origins, and the latest results from observatories and satellite experiments.

  1. 28. Tau neutrino measurement using track sample in IceCube

    At the IceCube Neutrino Observatory, muon neutrinos are identified by characteristic long tracks due to high energy muons through the charged current (CC) interactions. On the other hand, ~17% of tauons resulting from tau neutrino CC interactions decay to muons and produce long tracks. However, energy sharing between hadronic showers and a muon is different between muon neutrino CC interaction...

    The SNO+ Experiment is a versatile liquid scintillator neutrino detector situated at SNOLAB, with the primary goal of searching for neutrinoless double beta decay. In addition to ongoing measurements of reactor antineutrinos, solar neutrinos, geoneutrinos, supernova neutrinos, and other exotic phenomena, the SNO+ experiment is now preparing for an upcoming phase capable of neutrinoless double...

    Neutrinos produced in the highest energy extragalactic phenomena propagate through space, preserving energy and direction. Detection of these ultra-high-energy neutrinos can act as a telescope and as a method to probe physics at a new energy scale. At the EeV energy scale, neutrino-induced electromagnetic showers can be observed via the Askaryan effect. As the shower traverses a dense medium,...

  4. 25. Constraining Fuzzy Dark Matter With Galactic-Center Resonant Dynamics

    Parallel talk

    In this talk I will discuss the influence of axion dark-matter cores on the orbits of stars at the Galactic center. This dark matter candidate condenses into dense, solitonic cores, and, if a supermassive black hole is present at the center of such a core, its central part forms a `gravitational atom'. Here, I will present a calculation of the atom's contribution to the gravitational potential...
